Using vermicompost and vermitea increases rice yield and generates higher income, according to Magsasaka Siyentista (MS) Rene Sebastian in a recent technology field day and forum held in this town. MS Sebastian attributed these positive results to his application of science and technology (S&T)-based interventions in his farm in Barangay Sto. Cristo. [caption id="" align="alignnone" width="500"]vermicompost photo Photo by jeffschuler [/caption] Sebastian also reported that his farm became a source of quality seeds. His clients include the Department of Agriculture and farmers from adjacent barangays. The S&T interventions According to Sebastian, he produces his own vermicompost and vermitea. He also does not burn rice straw, instead he transforms it into organic matter by adding in chicken manure and some microorganisms. As to the other S&T interventions, he plants the recommended NSIC-Rc 18 rice varieties; applies 25 bags of vermicompost in the last harrowing; and uses inorganic fertilizer, 5?7 days before panicle initiation. He also uses vermitea as foliar fertilizer. Further, he applies pesticide at 40 liters/ha within a two-week interval, from transplanting time to panicle initiation. For the first crop cycle, he incurred an additional cost of P4,500 for the 14.5 bags of vermicompost; however, an additional amount of  P3,000/0.5 ha too was gained from the S&T intervention compared with his traditional farming practice.  He expects higher income in the next cropping cycle as organic matter builds up. On the same occasion, Dr. Cielito A. Beltran, a technical expert from the Tarlac College of Agriculture (TCA), further discussed the science behind the practice of MS Sebastian. He presented the procedure of making vermicompost and vermitea.  Vermicompost is the material that worms consume that is converted into cast with large quantities of nutritional organic compounds.  On the other hand, vermitea is formulated from worm castings, which are soaked in water for 24 hours and oxygenated. Dr. Beltran pointed out that the use of vermicompost and vermitea is a biological method of fertilization and pest control that can increase rice productivity up to 28%. At the same time, these organic products can reduce the cost of production by more than 50% through continuous application. In closing, he emphasized the readiness of TCA in providing training to all interested farmers. However, because of its limited finances, TCA requires farmers to provide counterpart funds. The conduct of technology field day and forum was a collaborative undertaking of the Municipal Agriculture Office of Concepcion, Tarlac, TCA, Central Luzon Agriculture and Resources Research and Development Consortium, and PCARRD.

The battle against Brontispa continues

The enemy creeps in silently, attacking unopened young fronds. As the spear unfurls, it moves on to its next victim. Brontispa longissima (Gestro) or coconut leaf beetle entered into the Philippines through the shipments of ornamentals. With the palms as its point of interest, the insect chews leaflets causing the young leaves to appear scorched as a result of damage. In the Philippines, Brontispa feasted on the most ubiquitous palm, the coconut. From August 2007 to March 2011, Brontispa longissima, with its invasive and destructive infestation, has already affected more than three million coconut trees. Thus, the silent pest made a resonant impact to the coconut industry – a threat that cannot be allowed to intensify. The coconut industry is one of the leading sectors of the Philippine agricultural economy. A total area of 3.26 million hectares (M ha) is devoted to coconut. Being the leading export agricultural commodity, it ranks as the second largest contributor to Gross Value Added (GVA) equivalent to 6%. As reported, 3.5 million farmers/farm workers are directly employed and 25 million Filipinos are being supported through diversified income source. With the alarming situation, the Philippine Coconut Authority (PCA) spearheaded the Brontispa Action Program. The program seeks to determine the extent of infestation and level of damage of Brontispa in the country. PCA initiated an aggressive and sustained information campaign; conducted emergency control activities using pesticides; and trained personnel and farmers on available control strategies. However, the application of pesticides provided only temporary relief since recurrence and re-infestation occur as soon as the effect wore off. Such observation, considering the economics and environmental impact, paved the way for the use of biological control as an alternative approach that can effectively and sustainably manage Brontispa population. Building on earlier R&D outputs and field experiences, the research team of Ms. Cynthia Gallego of PCA-Davao Research Center proposed a project titled “Development of an Integrated Pest Management (IPM) against Brontispa longissima (Gestro), an invasive pest of coconut and other palm species”. This is in collaboration with PCA’s Albay Research Center (PCA-ARC) and the Philippine Nuclear Research Institute. The project consists of six component studies, namely: Survey and mapping of Brontispa longissima (Gestro) occurrence, its hosts and indigenous natural enemies; Mass production of promising natural enemies of Brontispa longissima (Gestro); Crop loss assessment due to Brontispa longissima (Gestro) infestation; Field testing and integration of control strategies against Brontispa longissima (Gestro); Information campaign and IPM promotion in Brontispa-infested areas in the Philippines; and Effects of gamma irradiation on the sterility of Brontispa longissima (Gestro). The three-year project is expected to develop and promote application of cost-effective, environmentally sound IPM strategies against Brontispa longissima that are technically feasible and socio-economically acceptable at the farm level. Coconut farmers, decision makers, researchers, and local government units are expected to benefit from this project. Incidentally, the project will be funded by the Department of Science and Technology (DOST) and will be coordinated and monitored by DOST-PCARRD.

A module titled "Profitability Analysis: Coconut Sap Sugar Production," published by PCARRD explains the process of producing coconut sap sugar. The module was based on information adopted by PCARRD from the Philippine Coconut Authority. The production process is ideal in the farm level and can produce a high-value product from the sap of the coconut inflorescence. It involves a natural process of heat evaporation to convert liquid sap to solid form of sugar granules. coco sugar The process consists of six stages: selection of tree and mature inflorescence for tapping; collection of coconut sap; heat evaporation;conversion of sap syrup to coconut sap sugar; sieving and drying; and weighing and packaging. Step 1. Selection of tree and mature inflorescence for tapping 1. Select bearing trees with healthy unopened inflorescence for tapping. 2. Bend the mature unopened inflorescence downwards for one week to allow the flow of the sap for tapping. 3. Tie the inflorescence with plastic twine and slowly pull them downwards. 4. Using a sharp knife, tap the inflorescence by slicing at least 6 mm to cut the tissues and eventually allow the surge of the sap. When the tip of the unopened coconut inflorescence is cut out, the sap slowly flows out. Step 2. Collection of coconut sap 1. After slicing the unopened inflorescence, collect the liquid sap oozing out with the use of a plastic vessel. The collected sugar liquid has about 12–18% sugar content. Coconut sap is known to contain important amino acids, minerals, and vitamins. 2. To avoid the fermentation of the fresh sap, start its collection five hours after tapping. A total of 850 liters of sap ready for processing can produce 100 kilo of sugar. Step 3: Heat evaporation 1. Boil the collected sap up to 115°C using a brick-fabricated oven locally known as "pugon." The oven has improvised chimney where smoke will be emitted to ensure smoke- free smelling sugar. 2. When the liquid is already boiling, the scum will come out and this has to be removed to avoid the formation of dark residues on the final product. 3. The boiling of the sap will take about 3–4 hours to remove water, leaving the sugar content of the coconut sap. Step 4: Conversion of sap syrup to coconut sap sugar 1. Transfer the liquid to food grade stainless wok when it turns into syrup. 2. Stir the syrup continuously to avoid burning and to ensure granulation. At this phase, the liquid will change into solid form, hence, temperature change is critical. Stirring allows air to enter the sticky syrup that will cause the gradual cooling resulting to granulation. 3. Remove wok from the fire and transfer it to a wooden trivet. Stir until the sugar granules are formed. Step 5. Sieving and drying the coconut sap sugar 1. Let the sugar cool off and continue pressing to break the lump. 2. Sieve the sugar to have a uniform particle size to produce quality product. 3. Put the sugar granules in a food grade stainless tray and let dry for one hour to lessen the moisture content. Step 6. Weighing and packaging 1. Collect the sugar in a big container and store overnight. 2. Weigh and pack the sugar using the commercially available transparent polyethylene plastic bag (.03 in x 8 in x 5 in). Compared with refined cane sugar, coco sugar has a lower glycemic index (GI), which makes it suitable for use by health buffs and diabetics. Having a low GI means that people who consume coco sugar will not experience sudden spikes in their blood glucose or blood sugar levels. Packed coco sugar is sold at P200 per kilo. With a production cost of P153.50, including labor, management, and packaging cost, students earn P46.50 per kilo. Source: PCARRD. Profitability analysis: Coconut sap sugar production module.

The Philippines ranks 12th among the top producers of mango in the world, with 2% share in production (FAO, 2012). It is also the third most important fruit crop based on export volume in the Philippines, next to banana and pineapple.  It has very high potential as fresh or processed export product to other untapped export destinations.  However, mango production in the Philippines is still constrained by a number of problems that limit its full potential. These include occurrence of pests and diseases, poor soil nutrition, low adoption of improved technologies, and high post-harvest losses, that cause substantial reduction in fruit yield and quality.

The Industry Strategic S&T Program (ISP) for mango aims to address identified problems in the mango technology chain by providing science solutions in the form of science and technology (S&T) interventions with corresponding resources to achieve desired targets. The ISP for mango aims to increase yield by 90% (from 5.82 mt/ha to 11.11 mt/ha), reduce postharvest losses by 50% (from 40% to 20%), and enhance the capability of mango growers on Integrated Crop Management (ICM), Postharvest Quality Management (PQM), and Good Agricultural Practices (GAP).

Two major programs on mango were crafted to come up with holistic approach in addressing identified gaps. Some of the outputs of the National Science and Technology Program for ‘Carabao’ Mango (NSTPCM) include the putative mango hybrids with target traits such as red blush and thick skin, and resistance to pests and diseases; optimized management strategies against mango pests; developed geodatabase, suitability and vulnerability maps; and produced diagnostic kit for identification of true-to-type ‘Carabao’ mango variety. Under the Advancing the Philippine Mango Industry: Production of Export Quality Mangoes Program or APMI:PEQM, pre- and postharvest equipment such as mechanical fruit picker, low-volume power sprayer, and model integrated postharvest facility have been developed. Mango growers, contractors, and LGUs were trained on ICM, PQM and GAP for mango.

The ISP for Mango, among other ISPs, as a program, has been conceived by the government through the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD) in 2012. The Program seeks to provide the vision and direction for all actors and key players in the agriculture, aquatic, and natural resources sectors in the Philippines. DOST-PCAARRD will showcase the ISP for mango including other science and technology (S&T) agri-aqua research and development (R&D) outputs on March 2-4, 2016 during the SIPAG FIESTA at its headquarters in Los Baños, Laguna. SIPAG, a technology transfer strategy, embodies the Council’s commitment to DOST’s Outcome One in a bid to ensure that the fruits of R&D activities for the agri-aqua sectors will be a blessing for every Juan. by Allan B.

Seaweed is one of the most important aquaculture commodities in the Philippines. Seaweed farmers usually enjoy a good harvest from January to June, which are considered peak months for seaweed farming. The most popular and commercially cultured species is the Eucheuma cottonii due to its fast growing characteristics and high market price. Seaweeds are exported either in raw form (fresh or dried seaweeds) or processed form (carrageenan and kelp powder). The major products derived from the utilization of seaweeds are: agar, algin or sodium alginate, and carrageenan. Carrageenan is a natural gum used as additive, binder, and emulsifier on food, pharmaceutical, beverage, and cosmetic industries. I. Materials 1,250 kgs. Eucheuma seedlings 1 unit Dugout banca 1 unit Stainless steel knife 5 units Wooden basket/seedbin 12 rolls Nylon rope #10 10 rolls Plastic straw 12 pieces Bamboo poles 12 pieces Anchor bar 25 pieces Empty sacks II. Procedure Eucheuma has two types: the cottonii (or guso) and the spinosum (or agar-agar). Both of them can be exported in dried forms. Of these two, cottonii grows faster and is easier to farm. 1. Site Selection * Choose a body of water where seaweeds are endemic; algae eel grasses and sea animals are abundant. * The sea bottom should be of hard sand or rocks with the water moving and holding the seaweed loosely. * Water depth should be at 1 or 2 feet at low tide and at least 7 feet at high tide. Depth should be determined so that seaweeds will not be overexposed to sunlight and air during low tide and will be exposed to enough sunlight penetration during high tide. * Seawater temperature should be between 27° and 30° Centigrade. 2. Acquisition of Permit to Farm * The proposed area must be surveyed by a geodetic engineer to determine the area's bearings and the exact size intended for the business. * After the survey, the applicant should acquire an official application form from the Bureau of Fisheries and Aquatic Resources (BFAR) and prepare all the necessary requirements as provided for by law. * Guidelines promulgated by the BFAR must be followed to the fullest to avoid cancellation of the application. * It should be noted that the application should be approved first before a permit is issued and before commercial farming commences. 3. Culture Preparation * Prepare the necessary materials and install the needed structures prior to planting. * Source out quality seedlings from the vicinity to ensure easy transport to the farm site; seedlings must be protected from direct exposure to sun and rain. * Transport container like styrofoam box is recommended although ordinary jute sacks will suffice. * Seedlings must be immersed in seawater upon arrival, preferably in the seedling bin. Seaweeds get their food from seawater brought in by water current, so once they are off the water for more than 12 hours and without pouring seawater into them in-between, seedlings will die. If the seedlings are placed in a container with inadequate ventilation, packed with too much pressure or if there is an increase in temperature in the container, seaweed seedlings will die. * Seedlings to be planted must be around 100-200 g. each. Choose healthy and strong branches; these are usually found at the center and near tips of a healthy plant. * Use a clean, sharp, stainless steel knife for cutting branches to leave a smooth surface. 4. Preparation of Materials * Prepare a measuring stick made of bamboo about 0.64 cm. (1/4 inch thick), 7.6 cm. (3 inches wide) and 20.3 cm. (8 inches) long. * Wind the plastic straw 25 times around the stick. * Insert a sharp knife and cut the straw at one end. * Cut similarly the straw at the other end. * Get one strip and tie it tightly around one end of the strips to make a bundle. * Split each strip into two and make a tight knot at each tip. * One strip is sufficient to tie one cutting (planting material). Tie nylon lines to stakes. * After clearing the area, measure the exact dimensions of the farm. * Commence posting by using the anchor bar. Position the stakes such that nylon lines will be parallel to the water current. Bamboo poles/wooden posts are driven to the bottom, half a meter between rows. * The lines are tied at both ends of the posts parallel to each other and 20-25 cm. from the bottom. 5. Maintenance * Visit the farm regularly. * Keep plants clean by removing mud and rough seaweeds. * It is essential to remove fish and other sea animals that may feed on the seaweeds. * Check and prune the disease-infected portion of the plants. 6. Harvesting * Harvesting may be done by pruning the branches and leaving portions of the plant to grow again or by taking all the plants and replacing them with new cuttings, which is best done before each plant reaches 1 kg. or after 45-60 days. * From the harvested plants, the best-looking plants are selected for use as seedlings for the next planting. * These may be stored in the seedbed if these cannot be planted immediately. * Harvested seaweeds are placed in bamboo baskets in the banca then sold raw at the market or dried for added value. 7. Drying * Seaweeds should be dried immediately after harvest, kept clean, and not allowed to come in contact with fresh water. * Solar drying is the most popular and low cost option, taking 2-3 days under ideal conditions. Spread thinly harvested plants on a raised platform or cemented pavement with mesh net, dried coconut fronds, or sawali. Overturn the seaweeds regularly to facilitate drying. * After drying, prepare the dried seaweeds for washing. Place them in a basket and wash in seawater by stirring and shaking the basket. * Spread washed seaweeds on the drying area for about 6-8 hours. 8. Marketing It is advisable to cultivate seaweeds through contract growing or trader financing to ensure a ready market. Buying and selling usually take place within the seaweed growing area. Seaweeds can also be sold to the nearest wet market. Estimated Annual Cost and Return of a 1/2 hectare Seaweed Farm A.

Mass producing the fragrant Kamuning

$

Kamuning or Murraya paniculata is a small tree that is famous for its fragrant white flowers that smell like jasmine. Native to Southeast Asia, China and the Malay peninsula, kamuningor Orange Jasmine has pear-shaped leaflets that are dark green and glossy. After each blooming period, its white blossoms turn into orange and scarlet fruits. murraya-paniculata-kamuning Before, kamuning was usually planted as a hedge or accent shrub for landscaping purposes. Today, its glossy evergreen foliage is more popular as fillers in flower arrangements. Recent surveys show that fillers now occupy a substantial share in the cutflower business. A recent survey says that cut foliage or fillers make up almost a third of bouquets compared to 5% 10 years ago. To meet the increasing demand for foliage plants, the Institute of Plant Breeding of the University of the Philippines at Los Baños (IPB-UPLB) has identified techniques to mass produce kamuning successfully. There are two ways to mass propagate kamuning, either through stem cuttings or seeds.

Propagation by stem cuttings

  • Preparation of stem cuttings
Secure healthy and woody 13-20 cm long stem cuttings. Remove 5-8 cm of the terminal stem to allow faster rooting. Choose cuttings with mature leaves. Place the newly harvested cuttings in polyethylene plastic bags then sprinkle with water to prevent from drying. Seal the bags with rubber bands.
  • The kulob method
Kamuning stem cuttings root faster in the kulob method wherein the whole system is enclosed in a polypropylene plastic bag. This method helps to maintain the humidity needed to initiate rooting. For extensive rooting, use appropriate media and rooting hormones. The steps involved in this method are as follows:
  1. Prepare rooting medium composed of an equal mixture combination of sand and coirdust. Drench with 1 tbsp fungicide dissolved in 4 liters of water.
  2. Dip cuttings either in "quick root powder" or in 50 ppm alpha napthalene acetic acid (ANAA) or Hormex for 30 minutes.
  3. Stick the cuttings, 4 cm deep, in a 6x6x11 plastic bag containing the medium. Use bigger pots if more cuttings will be planted. A maximum of 4-6 cuttings can be planted in a 6x6x11 plastic pot.
  4. Enclose the whole system with a polypropylene plastic bag and seal with rubber bands.
  5. Place the kulob plants under shade.
  • Transplanting
After 6-8 weeks, roots are already established. Transplant rooted cuttings as follows:
  1. Transplant individually in 6x6x11 plastic bags containing either an equal mixture of sand and coir dust or soil and coir dust.
  2. Acclimatize transplanted plants under partial shade for one week before exposing them to full sunlight. Well-established kamuning plants can tolerate both partial shade and full sunlight conditions.
  3. After one week, apply complete fertilizer (14-14-14) at 2 tbsp in 4 liters of water. Repeat every other week. Apply urea (46-0-0) at 1 tbsp. dissolved in 4 liters of water once a month. Slow release fertilizer (17-17-17) could be applied once in every three months. Plants that are transplanted should not be fertilized too often.
  4. Water the plants daily during the dry season and minimally during the rainy season.

Propagation by seeds

  • Preparation of seeds
  1. Harvest ripened seeds from the mother plant. Ripe seeds may be orange/red orange to deep red depending on the variety or strain of the plant.
  2. Soak the seeds in water for 3 days . After 3 days, remove the pulp of the seeds and wash with clean water.
  3. Air-dry the seeds for a few hours before sowing.
  • Germination
  1. Sow the seeds by spreading them evenly in a polyethylene bag containing an equal combination of either the following mixture: sand + coconut coirdust or burnt ricehull + sawdust.
  2. Cover the seeds with 1 cm layer of the medium and place in a shaded area.
  3. Water the seeds only when the surface of the medium appears dry.
  • Transplanting
  1. Kamuning seeds usually germinate 2-8 weeks after sowing. Transplant seedlings one week after germination or when the first pair of leaves emerges.
  2. Transplant individually in a 2.5x2.5x5 plastic bag containing an equal combination of any of the following medium: - garden soil + coirdust - sand + coirdust - burnt ricehull + coirdust.
  3. Keep the newly transplanted plants in the shade for at least one month. Kamuning seedlings grow best under partial shade. Direct sunlight causes yellowing and scorching of the leaves.
  4. Apply complete fertilizer (14-14-14) two weeks after germination at 1 tbsp/4 L of water. Repeat every other week. Urea (46-0-0) at 1 tbsp/4 L of water should also be applied once a month.
  5. Water the plants daily during the dry season and minimally during the rainy season.

LGUs pressed to adopt ‘carbon credit-eligible’ charcoal briquetting as a Solid Waste Management approach

$
0

Local government units (LGUs) have been pressed by the Ecosystems Research and Development Bureau (ERDB) to adopt a solid waste management system through charcoal briquetting that can earn for them equivalent “carbon credits.”
   Charcoal briquetting will also enable many LGUs to comply with the Solid Waste Management Act (SWMA).  Many LGUs have not yet complied with SWMA of year 2000, also Republic Act 9003, almost 20 years now since it was ratified.
   An intensive training and a possible supply chain linkage is offered by ERDB to LGUs through a charcoal briquetting program. 
   This produces charcoal without having to cut trees.  Thus, it can earn for LGUs equivalent “carbon credits” under possible new carbon finance schemes of the United Nations Framework Convention on Climate Change or UNFCCC.
   ERDB Executive Director Dr. Henry A. Adornado expressed satisfaction that ERDB’s research on the production of charcoal briquette has reached a success level for small communities including one in Barangay Lower Bicutan C6, Taguig City.
   "We are open to sharing the technology to any sector interested in learning from us. We provide trainings and free demo as part of our collaborative program in technology transfer and extension," said Adornado.
   LGUs can raise funding specifically from this program which fits under a potentially new UNFCCC (United Nations Framework Convetion on Climate Change) financing incentive for reducing deforestation. 
   It is called Reducing Emissions from Deforestation and Forest Degradation (REDD) Plus expected to be approved by end-2015.
   The need for fuelwood in many Filipino households has led charcoal-fuelwood producers to cut trees.  They destroy forests including virgin forests, consequently emitting carbon dioxiode.  
   The ERDB initiated training for a program on charcoal briquetting in Brgy. Lower Bicutan C6 that has generated jobs for persons with disability (PWDs).
   "We're glad that this success story can inspire many other grassroot communities to venture into charcoal briquetting. If persons with disabilities can succeed in it, why can't anyone else?" said Adornado.
      The PWDs are now renting a small charcoal briquette factory in an estimated 200 square meter site in Taguig City.
    Members of the Samahan ng May Kapansanan sa Taguig (SAMAKAT) are using ERDB’s charcoal briquetting technology as an environment friendly way to supply wood for cooking in Taguig parish communities.
   After an intensive skills training, SAMAKAT PWDs  acquired the ERDB-developed machinery through the financial assistance of Pondo Pinoy of a Taguig Catholic parish.
   The machineries are a carbonizer, mixer, briquettor, and dryer. Among the jobs for 12 PWDs raw material gathering and simple machinery operation.
   Women PWDs also get hired for packaging. A 24-piece briquettte is sold at P20 per pack and generates an income of around P100 per day for each PWD, according to SAMAKAT President Mario Galvez
   The ERDB charcoal is more cost efficient than ordinary charcoal and emits a steady heat with low clean flame. The charcoal is easy to ignite.
 
   "Charcoal briquetting has given new lives for people like us. Now, persons with disability can look up because they have a contribution to society," said Galvez, himself an orthopedic PWD.     
   A training session on producing environment-friendly charcoal was held three years ago by ERDB Researcher Engr. Santiago Baconguis Jr.
   Baconguis introduced the techniques on how to come up with charcoal briquettes from various biodegradable waste materials. These waste materials have now become of huge economic value.
   Among the waste materials that SAMAKAT uses are from buko juice merchants and water hyacinth (water lily) directly gathered from the Laguna Lake.
   Compliance to the SWMA has been a challenge for many municipal, city and provincial governments.
   And ERDB could be of assistance in managing their wastes using DENR-ERDB’s CBT.
 
          ###
 
BACKGROUNDERS
 
ERDB charcoal briquettes
 
   The carbonized charcoal of ERDB is more efficient.  A three-meal Filipino household needs only 1.69 kilos of ERDB charcoal compared to 3.5 kilos of ordinary charcoal.
   Charcoal briquettes of the ERDB technology can be considered a renewable energy  (RE)similar to biomass which mostly comes from waste materials.  It should receive incentive from RE programs.
   Charcoal briquettes are more cost efficient than unprocessed fuelwood.
   Unlike fossil fuel (petroleum) energy sources that can be depleted, charcoal production can be replenished much as other RE (solar, wind, biomass).
   An ERDB study indicated “charcoal briquettes from wood and non-wood biomass wastes such as leaves, twigs, branches and other cellolusic biomass can lessen wood and wood charcoal consumption of poultry farms, households and domestic business.”
   In a project study involving use of 300 kilos per day of  biomass waste, ERDB reported investment here results in a 100 percent internal rate of return, making it a very viable business.
   “Positive externalities are the potential for carbon sequestration (1.53 million kilos in 10 years), landscape amenities it will provide, protection of biodiversity (flora and fauna), among others,” ERDB said.
  The charcoal production  from this project is 5.4 million cubic meters (cu.m.) per year fuelwood from the forest and woodlands or an equivalent charcoalof 1.35 million metric tons.
    This project will spare 6,970 trees yearly.
 
 
REDD Plus ‘Carbon Credits’
 
   Philippines’ renewable energy (RE) projects such as the Bangui wind plant in Ilocos Norte have benefited from carbon credits from UNFCCC-initiated agreements.
   LGUs and other entities may earn new financing from a program being introduced by UNFCCC negotiators called the REDD Plus (Reducing Emissions from Deforestation and Forest Degradation). 
   The original carbon credits gave financing for projects that reduce emissions of carbon dioxide and other greenhouse gases. 
   The REDD Plus is specifically targeted at giving potential financial incentives for reducing deforestation. It is expected to be approved by end-2015.
 
Kaingin
 
    Fuelwood in general is extensively used not only in Filipino households but in small rural businesses such as bakeries and restaurants based on a study.
   However, this has caused massive forest degradation through a highly destructive technique “kaingin” (burning of forests).
    It was estimated that the country’s charcoal consumption is 2-4 million metric tons yearly.  For total fuelwood (including freshly gathered wood) andcharcoal, estimated yearly consumption is 25–35 million metric tons yearly.
   Charcoal production from waste materials can reduce forest degradation.
   Studies indicated much of forest destruction is due to the need for cooking fuel.
   For instance, in Cebu, cutting of trees wasted noted to e a major cause of deforestation particularly of primary forests.
    “The province of Cebu is now in the stage where firewood is becoming scarce. The situation is so severe that the remaining forest resources are exploited at least three times their sustainable yield,” according to a DENR report.  ###

Philippine government pressed to put policies to bring GM crops like Vitamin A-rich rice to help solve worsening global hunger, malnutrition

The Philippines needs to put policies needed to bring to the poor genetically modified (GM) crops like the Vitamin A-rich rice to help solve worsening hunger problem globally. Food production needs to be raised by 70 to 100 percent in the next 30 years according to the Food and Agriculture Organization (FAO). This is as population is seen to rise to nine billion by 2050 from the present seven billion. And GM technology can raise food production and nutrient level in crops, making it possible to meet the increasing food demand, according to Dr. Wayne Parrott of the University of Georgia-Institute of Plant Breeding, Genetics, and Genomics. Parrott visited the Philippines last week in the aftermath of the uprooting of Golden Rice plants under field trial in Camarines Sur. While GM crops are a positive development, the government has to make decisions that will determine whether this increase in food production will happen. “We have the technology to meet the need of the future. What we don’t have yet is the will power, the regulatory system to allow use of the technology that we need,” Parrott said. The Philippines is liable to the poor of the world in helping solve hunger and malnutrition problems. The Philippines is host to the field trial of the Vitamin A-enhanced Golden Rice being conducted by the International Rice Research Institute based in Los Banos, Laguna and the state-run Philippine Rice Research Institute. The country is also host to the field trial of the GM Bacillus thuringiensis (Bt) eggplant by the state-run Institute of Plant Breeding of the University of the Philippines Los Banos. Rice is the most consumed food in the world. The nutrient content in rice determines whether hunger and malnutrition are reduced as it is a staple of around 50 percent of global population particularly developing countries in Asia. Eggplant is the most consumed vegetable in Asia including developing countries as Philippines, Bangladesh, and India. “The recent destruction (of Golden Rice plants) that took place in the Philippines attracted global attention. The global spotlight is now on the Philippines because Golden Rice gets more positive press in the world,” said Parrott. Golden Rice efficacy The National Institutes of Health in Maryland reported that Golden Rice contains up to 35 micrograms of betacarotene and is“effectively converted to Vitamin A in humans.” Golden Rice is enough to eliminate symptoms of Vitamin A deficiency just by a regular intake of 50 grams per day. [caption id="attachment_6103" align="alignnone" width="600"]Vitamin A-rich Golden Rice Beams in Rich Yellow Vitamin A-rich Golden Rice Beams in Rich Yellow[/caption] Golden Rice’s bioavailability or its conversion into Vitamin A in the human body has been tested favorable on the target Vitamin A-deficient patients. “If it’s approved, the Helen Keller Foundation for the blind will do monitoring of Golden Rice (efficacy),” Parrott said. “There are 500,000 cases of irreversible blindness each year. It doesn’t stop there. If you’re Vitamin A deficient, you’re predisposed to other diseases. There are two million deaths from complications due to Vitamin A deficiency. And we can do something about it,” he said. Consumers should look at GM crops as a way to help solve food shortage. “GM technology is part of the solution, not part of the problem. We’re better off if we consider it as a way to solve the problem to be solved,” he said. Bt eggplant Filipino scientists developing the Bt eggplant assert the safety to the environment and human of the protocol used to test it. That is amid a “writ of kalikasan” stopping field trials issued by the Court of Appeals. “We have put in place for the last 12 years a protocol. We have had so many field testing with no proof or evidence that that it has harmed the environment or the Filipino people,” Dr. Desiree M. Hautea, Bt eggplant project leader. The protocol is of international standard agreed upon between countries under the Cartagena Protocol on Biosafety. Bt eggplant was developed to solve infestation problems of fruit and shoot borer (FSB) causing harvest losses in eggplant. FSB prompts farmers to spray pesticides on eggplant 25 to 80 times spray during a 120 to 170-day growing season. [caption id="attachment_6104" align="alignnone" width="600"]Eggplant on the right infested with pest compelling farmers to spray up to 80X per season, Bt eggplant (left) is clean Eggplant on the right infested with pest compelling farmers to spray up to 80X per season, Bt eggplant (left) is clean[/caption] Spraying harms farmers, and eating the eggplant brings bigger harm to consumers. Farmers do not always observe international food safety standard that fruits should be harvested 30 days after the last pesticide spray. Some farmers in Pangasinan were found to even be dipping eggplants in a bucketful of pesticides in order to ensure these are not FSB-infested. Malnutrition The increasing global population poses worsening hunger threats if newer technology is not introduced. It is a specifically a problem in tropical countries like the Philippines. “There were one billion people who were hungry (malnourished) in 1960 when the world had three billion population. One of three people was hungry. Now the world has one billion people who are hungry when the population is seven billion. The percentage of hunger has gone down but total numbers have not,” said Parrott. Ten years in the decade, people are eating more than what is produced globally, thus the worldwide crisis in food. Receding farm land Numerous challenges face policymakers and scientists in solving the problem. There is not much land and much water to feed the world. There was 4.3 hectares per person of arable land in 1960 when there was only three billion population. But arable land has been receding to 2.2 hectares per person in 2000 and lower to 1.8 hectares per person in 2011. It is projected to further reduce to 1.5 hectares per person by 2027 when population will have reached eight billion. Preserving biodiversity is another challenge. GM crops may contribute to preserving biodiversity. GM crops require less land to yield the same amount of production or higher. Bt corn, for instance can yield seven to 10 metric tons (MT) per hectare compared to conventional crops yielding three to five MT per hectare. Another challenge is agriculture uses too many insecticides and pesticides that harm human and the environment. GM papaya The GM ring spot virus-resistant papaya has been one of the earliest GM crops consumed by human and has long been proven safe. In ring spot virus-resistant papaya, the only difference from conventional papaya is just one gene. “In Hawaii, papaya (or pawpaw) is their main agricultural export. This virus is attacking their papaya. It’s GM papaya that saved the industry. It was a collaborative effort between Cornell, University of Hawaii, and USDA (US <a class="StrictlyAutoTagAnchor" href="http://businessdiary.com.ph/tag/department-of-agriculture/" title="View all articles about Department of Agriculture here">agriculture/" title="View all articles about Department of Agriculture here">Department of Agriculture),” said Parrott. Small farmers It’s small farmers that benefit from GM technology. “There are about 17 million farmers around the world that use GM, about 16 million or 90 percent are classified as smallholders (tilling) 2.5 hectares or less,” he said. “Why will they invest in it? It’s profitable, and it makes life easier for them.” A study of PG Economics of London indicated that from 1996 to 2011, GM crops have generated $98.216 million in “value added” economic benefits. Countries that earlier adopted GM crop had higher economic benefits. Among the highest value added earners over the period were US, $43.38 billion; Argentina, $13.97 billion; China, $13.07 billion; India, $12.6 billion; and Canada, $3.98 billion. Philippines had $264 million in value added from Bt corn. Of the value added benefit, 50.5 percent came from higher yield and 49.5 percent from lower costs including omission of labor and pesticide spray. The higher 51 percent of the benefit went to developing countries, 49 percent to industrialized countries. “In China, India, Burma, Pakistan, Burkina Faso, South Africa, Paraguay, these are primarily smallholder farmers,” he said. “Farmers spend $53 per hectare for increased seed costs. But they save $52 per hectare for not having to use more insecticides. That’s only an extra dollar a hectare to switch from conventional to GM corn. They earn $202 per hectare in extra income,” he said. “In Honduras for every dollar smallholder farmers invest in GM technology, it gives them a return of $5.05.” In five major global crops – corn, cotton, soybean, bean, and potatoes-- some 20 to 30 percent is lost every year to pests and diseases. Simply stopping losses will go a huge way towards raising food supply. GM also has a way to reduce post harvest losses. There are non-browning potato and apple. These fruits do not easily get the oxidation effect of turning brown upon harvest compared to conventional fruits. GMOs Genetically modified organism (GMO) in food products are already part of the everyday human diet. There are GMs in “vitamins and supplements, insulin, modern vaccine, most beers and wines made with yeast, cheese, and artificial sweeteners.” “Yeasts are all over the world. And it’s not a cause for concern anymore. It’s only when we get to the GMO crops that people start to worry. But there is no difference in these two categories,” he said. Genetic modification is part of an agricultural system similar to how humans’ forefathers have selected superior crops based on certain characteristics such as nice-looking fruits and desirable taste or bigger yield. “We have been changing DNA (deoxyribonucleic acid-- the molecule that determine genetic traits) for many centuries even though we don’t realize what we’re doing. It’s impossible to change what the crops look without changing the DNA underneath them,” he said. If the disease resistance against the pest corn borer, for instance, is not in a wild relative of the corn plant, the gene may be obtained from another specie. In the particular case of Bt corn, the disease resistant gene Bt was obtained from Bacillus thuringiensis which is a bacteria naturally occurring in the soil. Bt is actually considered an organic pesticide used traditionally by organic farmers to weed pests and is totally safe to human. [caption id="attachment_6105" align="alignnone" width="600"]Clean GM Bt corn-- The clean one on top is GM Bt corn, the borer-infested below is conventional corn. Clean GM Bt corn-- The clean one on top is GM Bt corn, the borer-infested below is conventional corn.[/caption] Parrott himself had 25 years of research on genetic engineering. “It is sometimes easy for mere consumers to conclude GM crops are harmful. What they don’t know are the problems facing farmers everyday,” he said. These are pests like soybean leaf with aphids, Asian rust in soybean, sooty mold in citrus, powdery mildew in beans, squash or tomatoes. “That’s what farmers face in the field every day—pests. It’s easy to understand why farmers want GM technology.” Farmer health risks Farmers themselves are exposed to health risks by using insecticides and pesticides. Yearly, three to four million farmers poison themselves annually and about 300,000 die from pesticide practices. “It’s not only an environmental concern but a public health concern,” he said. GM crops have been successfully planted on a cumulative 17 billion hectares over the last 17 years with proven safety record. Planting involved more than 17 million farmers in 30 countries. “That means when people ask questions about GMO or express concern, we can answer based on real experience. We don’t need to be guessing. We don’t need to be speculating. We’ve got the answers,” he said. However, there are some 160 countries on earth, “leaving a large number that has no access to GMO and can’t experience it first-hand.” “Half of the population is in cities. They haven’t seen GMO in person and really don’t know what they’re talking about,” said Parrott. Many GM crops Herbicide-tolerant GM crops enable farmers to omit plowing, reducing their labor costs. It also restores the soil and the environment. “No tillage” or conservation tillage is possible with GM. “All farmers do is punch a hole on the ground. The dead weeds are protecting the soil. In Central America where they have torrential rains, this is preventing soil erosion. It prevents soil from washing away,” he said. With herbicide tolerant crops like those in corn, farmers may use herbicide without killing the food crop itself. Only the weeds are killed. Moreover, with Bt corn that kills only the target pests, friendly insects like bees and butterflies proliferate and become part of the healthy biodiversity. Cancer-causing fungi A serious problem linked to the activity of pest earworms on corn is the growth of cancer-causing fungi on corn. But GM technology has solved this fungi problem on crops by preventing pest resistance in seeds. People have to resort to eating infested corn when there is little yield even if it poses health risks. “The wounds that earworms make on corn become infected by a fungi. Depending on the type of fungus, fungus can do a lot of toxins. In areas like China, Africa, Central America where these toxins exist, they have high rate of liver cancer,” he said. And the most affected by this fungus and health risks are smallholder farmers such as those in Honduras. “In South Africa, they get 20 percent increase in yield simply by switching to Bt corn. In Latin America, caterpillars can do a lot of damage. But there is an insect resistant soybean. There’s also a rootworm resistant maize,” he said. Climate change As climate change persists, one of the predictions is it will be dryer in many areas with a smaller amount of rainfall. GM crops can resist drought, heavier rainfall, and other environmental stresses. “Last year, America had one of the (worst) droughts ever. Engineered corn had gotten through the drought.” In Brazil, the government co-developed the GM Brazilean bean that is resistant to golden mosaic virus. “Their staple crop for the countryside is dry beans. What’s impressive is it has higher yield for farmers. They’re investing in this to promote food security,” he said. The US Agency for International Development (USAID) funded the moth-resistant potato. Other GM crops being developed are the pod borer-resistant cowpea in Nigeria, bunchy top virus resistant banana in the Philippines, water efficient maize (corn) for Africa, and the mosaic virus-resistant-cassava in Africa.

Lettuce (Lactuca sativa L.) is the most popular salad vegetable. Its high fiber but low nutrient value makes it an ideal vegetable for those who watch their diet. [caption id="" align="alignnone" width="500"]lettuce photo Photo by Cara St.Hilaire [/caption] There are many types of lettuce. The most popular locally is the crisphead type which includes green and red iceberg varieties. The loose-leaf type includes grand rapid type varieties. Oakleaf and Lollo Rossa. Other types are Romaine/Cos and the Butterhead/Boston and Bibb lettuce. Production Management
Type Variety Leaf Color Maturity
Ice berg Great Lakes 54 green 45-50
 Great Lakes 659 green 45-50
West Lake green 45-50
Romaine/Cos Lital dark green 50-60
Noga green 50-60
Parris Island green 50-60
Loose-leaf Samantha red 45-60
New Red Fire red 45-60
Climatic Requirements Lettuce is a semi-temperature vegetable requiring cool temperatures of 15-20oC. The iceberg varieties will not form heads in hotter areas. It can also be planted in low elevations during November to December. The quality is best in high elevations (1000 m asl). Seedling Production About 150-200 g of seeds is required per hectare. The best method of seedling production is by line sowing in seed boxes or nursery beds with a soil mixture of 2 parts garden soil, 2 parts manure and 1 part rice hull charcoal. Water before sowing. Make lines 7-10 cm apart. Sow 200-400 seeds/m. Cover with the same mixture and mulch with rice hull of fine rice straw. Water daily and prick to nursery trays with the same soil mix after germination. Maintain under partial shade and harden by exposure to full sunlight one week before transplanting. The seedlings are ready for transplanting 3-4 weeks from sowing. Land preparation Prepare the land thoroughly. Make beds 0.75 - 1.0 m wide. Incorporate generous amounts of animal manure at 10-20 t/ha. Use rice hull to improve soil texture. Transplanting Water the beds properly before transplanting. If rice straw is available, mulch the beds and transplant at 30-40 cm x 30-40 cm, 2-3 rows/bed. It is best to intercrop onion, chives or garlic in the beds with marigold. Irrigation Water the plants regularly. Use furrow irrigation, if available. Mulching helps conserve soil moisture. Fertilization Apply sufficient animal manure at transplanting. Use tea manure or legume tea once a week, or as needed. Prepare tea manure by soaking manure in plastic drum. After two days, the resulting mixture, tea manure, is used as fertilizer to boost plant growth. Legume tea is prepared by soaking leaves of ipil-ipil or madre de cacao in water. The mixture is ready after 6-10 days. At transplanting, use 10g 14-14-14/hill as basal fertilizer side-dress with 5-10 g urea (46-0-0)/plant at 2-3 weeks after transplanting. Pest and Disease Management Lettuce has few significant pests and diseases. In case of cabbage looper and aphids, use botanical pesticides or soap solution. Bacterial rot can be minimized by sanitation. Harvesting and Postharvest Harvest iceberg lettuce at 45-60 days from transplanting, when heads are firm. Harvest loose leaf lettuce as needed, preferably before bolting. For large-scale planting, sort the heads in the field and pack immediately in perforated carton boxes. If available, vacuum cooling at 1oC is best. Transport at 4oC. Lettuce is the most important salad crop grown in most homes and school gardens throughout the country. Its leaves are eaten raw as an ingredient of salad. It is also used as decoration for other food preparations. The varieties commonly grown are Boston, Black Seeded Simpson, Iceberg, Grand Rapids and Great Lakes. This vegetable is planted anytime of the year provided there is an abundant supply of water. It thrives best, however, from September to February when the climate is relatively cool. HOW TO PLANT Sow the seeds in seed boxes or seedbeds. The developing seedlings are fertilized with ammonium sulphate. These seedlings are ready for transplanting 20 to 30 days after sowing. Plow and harrow the field until the soil is reduced to a very fine tilt. The land is divided into plots one meter wide and at any desired length. Provide a working path of about 40 cm between plots. Apply six to ten petroleum capfuls of mixed compost for every ten plots. Transplant the seedlings when two pairs of true leaves have developed at intervals of 30 cm each way. Transplant during cloudy days or late afternoon. Water immediately after transplanting and everyday thereafter for the plant's rapid continuous growth. Weed with bare hands or use a garden hoe. Lettuce can be harvested in 60 to 70 days from planting. Lettuce grown for home use can be harvested when plants are big enough for use. Aphids are the primary pests of lettuce. The most common diseases of lettuce are Bottom Rot, Gray Mold Rot, Brown Blight and Downy Mildew. Practice crop rotation and cleanliness. For the control of these pests, consult the nearest Bureau of Plant Industry office. Cabbage (Brassica oleracea L. var. capitata L.) is considered an important part of a well-balanced diet. It is usually eaten fresh or combined with other foods. Source: da.gov.ph

Mussaenda blooms year-round

Now, flower enthusiasts and gardeners can enjoy the spectacular display of Doña Aurora (Mussaenda philippicavar aurorae) and Doña Luz (Mussaenda erythrophylla) for they now bloom any time of the year. Scientists from the Institute of Plant Breeding of the College of Agriculture (IPB-CA) at the University of the Philippines Los Baños (UPLB) have made this possible with the new technology they developed that induces flowering in potted Mussaendas even if it is off-season.

Characteristics of Mussaendas

Mussaendas' spectacular beauty comes from its colorful bracts in large trusses- Dona Luz has large dark pink bracts, peach or pink bracts while Doña Aurora has white bracts with small yellow flowers in the center. Their leaves are pale-green and hairy. Both varieties are named after former first ladies. Aside from being a showstopper, Mussaendas are versatile plants that are relatively easy to grow. Most Mussaendas need lots of sun and thrive well in sandy soil. They can grow up to three meters. Mussaendas become dormant by shedding their leaves between December and April. At this time, they look dried up and dead. This happens when the temperature starts going down in the last week of December. Dormancy has also been linked to rainfall pattern and soil moisture.

Controlling the time of flowering by pruning

To induce Mussaendas to bloom even during the dormant period, the scientists single-pruned the seedlings leaving three healthy pruned stems per plant. The plants were fertilized once a week with urea and complete fertilizer alternately for a month. Dona Aurora and Dona Luz seedlings pruned in November flowered after 5 to 9 Weeks. Also, Mussaendas pruned in April and May took 4 to 5 weeks to flower while those pruned in June and July bloomed after 5 to 7 weeks. After the experiment, the scientists developed a protocol for producing small-potted flowering Mussaenda using cuttings of flowering shoot tips as the propagation materials. Backyard growers/cooperators in Los Baños were trained on the production of small-potted Mussaendas using the protocol below.

Protocol for producing small-potted flowering Mussaenda

  1. Harvest shoots at stage 1 flowering
  2. Cut the basal end of the cuttings
  3. Apply hormone at the basal end of the cuttings
  4. Plant cuttings in pots with a mixture of 1 part sand, 1 part coir dust and 1 teaspoon Multicote
  5. Place the cuttings in a misting chamber for 4 weeks
  6. Transfer rooted cuttings from the misting chamber to a place with partial shade for hardening
  7. Condition cuttings under partial shade
The mass propagation trial using the protocol was successful. The first flowering shoots were harvested in the first week of November 2001 and sold to Ayala Property Management Corporation. A cost and return analysis showed that the venture could be profitable for grower-cooperators. This is good news for farmers and entrepreneurs who are interested in selling Mussaendas especially during the Christmas season when these show-stoppers could be used to substitute the poinsettias that adorn many a Filipino home and workplace.

Organic Fertilizers from Farm Waste Adopted by Farmers in the Philippines

$

0

The Philippines' Department of Agriculture has been promoting the production of High Value Crops (HVCs) in order for farmers to earn higher income. Instead of using inorganic fertilizers, however, vegetable and fruit growers had been taught to use indigenous microorganisms (IMO) and fermented farm products as part of a nutrient management component based on the Korean Natural Farming (KNF). This is a system of farming which has been practiced in over 30 countries. This paper discusses the methods of preparing the common fermented farm inputs, particularly the Fermented Plant Juice (FPJ) and the Fermented Fruit Juice (FFJ). It likewise examines the variations in materials and processes and how these organic fertilizers from farm wastes are used in different areas in the Philippines.   Introduction The Oil Crisis of 2008 created a big stir in the agriculture sector mainly due to the escalating prices of inorganic fertilizers. With prices of fertilizers tripled, farmers were forced to look for alternative sources (as always) of nutrients in which the Department of Agriculture (DA), through the bureau of Soils and Water Management (BSWM) responded with the Project on Rapid Composting as a part of the DA's National Organic Agriculture Program addressed mainly to rice farmers. The project involves training and provision of shredders to capacitate farmers to produce their own organic fertilizers The High Value Crops (HVCs) sector however, has been taking a slightly different tact. Vegetable and fruit growers had been using indigenous micro organisms (IMO) and fermented farm products as a part of Nutrient Management based on Korean Natural Farming (KNF) through the assistance of NGOs and SCUs in various training and extension programs. "Korean Natural Farming" is a system of farming being practiced in over 30 countries. The basic premise in KNF is that farmers can generate most, if not all, of the necessary inputs to food production onsite. It is also the premise in the Philippine National Standard for Organic Agriculture. KNF is a holistic approach to farming that utilizes the nature's powers for maximum performance rather than human intervention. "Natural materials instead of chemicals as its unique inputs. Materials are locally available and cheap, and the farming inputs are made by the farmers instead of being purchased from the market; thus lowering cost for the farmers and converting waste into resources. Being "farmer-friendly," it is also being used as a tool to improve the living of the poor farmers in the third world." (Cho Han Kyu President of Janong Natural Farming Institute March, 2004). He attributed Natural Farming to three formless teachers and three human teachers. The three formless are God, Nature, and conscience. As now being regarded by many, the gains from `Green Revolution' is instant but the outcome is short term. We are now seeing the adverse effects of chemical fertilizers and pesticides not only on the soil that becomes acidic and low in organic matter, ground water contamination, adverse health effects but also on social and economic decay the latter due to the concentration of wealth on a few big companies. In contrast, Natural Farming is a sustainable way of farming making use of all inputs from natural materials, observes the law of Nature and respects the rights of crops and livestock. It heals the soil damaged by chemicals, herbicide and machines. In the words of the farmer practitioners… "The soil becomes virgin again". And " With chemical agriculture they get sick before harvesting the rice paddies, now not anymore". Common Fermented Farm Inputs Fermented Plant Juice (FPJ) Fermented plant juice (FPJ) or Bless Green Soup or Tenkei Ryokujyu is made by fermenting plant parts in brown sugar. Sprouts and baby fruits with high hormone concentration, full grown fruits, flower abundant in honey, and any plant with strong vigor are good ingredients. (http://www.janonglove.com/janong/bbs/board.php?bo_table=e_JN5 ). It is an ingredient in bokashi production and can also be used by applying directly to soil and plants. FPJ is produced by the fermentation of plant leaves, grasses, thinned crop plants, auxillary buds and/or young fruits and flowers (Jensen et al, 2006). It contains plant growth hormones and micronutrients that stimulate the growth of beneficial microorganisms. The common materials being used in the Philippines are kangkong (Ipomoea aquatica), sweet potato (Ipomoea batatas) and kakawate leaves (Gliricidia sepium). Materials (FPJ) Plant materials: leaves, grass, buds, young fruits, etc. Raw sugar or molasses at the rate of 1/3-1/2 of the plant material Procedure (FPJ) 1. Collect the materials early in the morning. Chop and finely mix these with sugar or molasses. 2. Place the mixed material in a suitable container such as earthen jar, or plastic drum if prepared in big volumes 3. Cover the pot or drum with paper or cheese cloth 4. Store in a cool dark place for 7-10 days to allow fermentation. The juice will change color from dark green to yellow brown or brown and would smell sweet and alcoholic. 5. After 7-10 days filter the material to extract the juice. Net bag can be used for small scale production. For big scale FPJ production, an improvised extractor or press can be used. 6. The FPJ can be stored in a glass or plastic bottle in a cool, dark place for up to 6 months. It is important not to tighten the cap completely on the bottle to allow aeration. Shake the bottle once a week to provide air to the microorganisms. Application method (FPJ) Dilute FPJ at the rate of 2 table spoonful per liter of water. Spray to plants or drench to the soil. Fermented Fruit Juice (FFJ) Fermented fruit juice (FFJ) is prepared in a similar manner to fermented plant juice (FPJ). It is used as a foliar spray to enhance fruit quality, as a feed supplement for animals, and as a food supplement for humans. In general, FFJ is generally used more during the flowering and fruiting stage. Materials (FFJ) Fruit peelings, over ripe fruits such as banana, papaya, watermelon, pineapple Raw sugar or molasses Procedure (FFJ) 1. Chop the over ripe fruits and peelings 2. Mix the materials with ½ part raw sugar or molasses. Other practitioners use 1:1 ratio. 3. Follow the same fermentation procedure as for FPJ. 4. Collect and store following the same procedure as for FPJ. Application method (FFJ) Use 1 tsp/5L water (minimum application rate for plants in healthy soil) or 1-2 tsp/L water (for plants in soil that is being rehabilitated) (Jensen et al, 2006). Apply to plants as a foliar spray. Fish Amino Acid (Faa) Fish amino acids are a good source of nitrogen for crop plants and may be used to supplement compost and manures in coastal regions which have a good supply of inexpensive fish byproducts. Some local government units (LGUs) such as Bayawan City in Negros Oriental is collecting fish trashes from the market for free and process this into FAA. Materials (FAA) Uncooked fish trash such as gills and intestines. Raw sugar or molasses Procedure (FAA) 1. Mix equal parts fish trash and brown sugar or molasses. Lactic acid bacteria serum (LABS) may be added to minimize the foul smell. 2. Place in earthen jar or any convenient container, cover with paper and allow the fish juice to extract and fermentation to occur for 14 days. 3. Filter out the solids and retain the liquid fish amino acids. 4. Store in glass or plastic bottles. Do not completely close the cap on the bottle. 5. Shake the solution weekly and add sugar to it every month (20% of the volume) as is done for IMO. Application method (FAA) Use 1-2 tbsp/L water and apply as soil drench or foliar spray weekly or depending on the vigor of the plants. High dosage can have adverse effects on plants. Calcium Carbonate (Caco3) Preparation from Egg Shells The main ingredient in eggshells is calcium carbonate. The shell itself is about 95% CaCO3 (which is also the main ingredient in sea shells) (Powrie, 1972). The remaining mass is composed largely of phosphorus and magnesium, and trace amounts of sodium, potassium, zinc, manganese, iron, copper and others, 27 in all. The CaCO3 is not in soluble form. To convert it into soluble form heat or acid treatment is needed. The common method in KNF is the combination of the two agents, heating and use of natural vinegars. Materials (CaCO3) Egg shells or sea shells including snail shells. Natural vinegar (made from coconut sap, sugar cane, pineapple or banana). Procedure (CaCO3) 1. Burn or roast the shells in open fire or over a hot tin sheet until the color changes from brownish to black in color. 2. Grind or pound the shells to a powder consistency. 3. Place in a suitable jar or plastic container. 4. Add 5-10 parts natural vinegar. Shake to produce bubbles indicating a good reaction between the shell and the vinegar. The bubbles are due to CO2 being released. 5. Cover with paper and store in a cool dry place. The concoction may be shaken from time to time to speed up the reaction. 6. The water soluble calcium is ready in 7-14 days when there is no more bubbling. 7. Filter the preparation and put it in a new container (a glass jar). 8. CaCO3 has a long shelf life and can be stored for up to a year. Do not shake or add sugar to the CaCO3 solution during storage. Application method (CaCO3) Use 1-2 tablespoon per liter as foliar spray or soil drench specially at the start of flowering to improve fruit set and fruit quality. Variations in Materials and Process 1. Materials in FPJ Different materials are being used by farmers in preparing FPJ. The most common and easiest to use is banana pseudo stem, particularly the Saba or Cardaba variety. A high FPJ yield is obtained using this material. Some practitioners are using just the roots of banana (var. saba) and using spring water to dilute the FPJ. 2. Materials in FFJ In FFJ, the materials being used are generally the most commonly available in the locality. In the case of the SOBAGROMCO squash and banana are the materials being used. Others use cucumber fruits, pineapple peelings, tomato and eggplant. 3. Materials in Caphos The common material is egg shell for CaPhos but in areas where sea shells are abundant these are also being used. The shells of Golden Snail (Pomacea canaliculata Lamarck) is also commonly used. In SOBAGROMCO the animal bones from slaughter houses are collected and converted into organic inputs. 4. Process and Ingredients There are generally two variations in the preparation of the fermentation products. The first one is just using the plant or fruit substrate and raw sugar or molasses. The second one involves the addition of one (1) part unchlorinated water. Water is added to hasten the fermentation process. Raw sugar or molasses is also adjusted to 1 part of the plant/fruit material. To save on raw sugar or molasses, the rate of this ingredient is also being reduced by some growers to as low as 1/6-1/10 of the plant/fruit parts. 5. Application The usual application rate is 1-2 tbs/liter of water applied as soil drench or as foliar spray. The combination of the different ingredients is based on the stage of plant growth. The KNFA recommends growth management on the basis of the Nutrioperiodism theory, which was developed and advocated by a Japanese horticulturist, Yasushi Inoue, in the 1930s. They emphasize the different nutritional requirements of crop plants at different growth stages. In Bayawan City, the proportion of the different preparations is 60:30:10 ratios depending on the stage of the plant. During the vegetative stage, it is 60% FAA, 30% FPJ and 10% FFJ. During the change-over, it is 60% FPJ, 30% FAA and 10% FFJ. During the fruiting stage, it is 60 % FFJ, 30% FPJ and 10% FAA. Utilization of the Fermented Farm Products 1. Organic Banana In organic banana production, the general guidelines in nutrient management are as follows: 1. Organic manure should only be seen as an additional fertilizer, and not as the main source of nutrients; 2. Regular application of organic material gained from cutting/pruning work helps to maintain a layer of humus and activity in the soil; 3. This includes adding dead leaves and pseudo-stems grown on the plantation as mulching material; 4. It is important that the material is spread evenly throughout the entire plantation; 5. These measures will suffice to maintain the fertility of the soil on sites suited to growing bananas, despite continual harvests. The organic inputs are the foundation of organic banana production in Toril, Davao City by the Sibulan Organic Banana Growers Multi-Purpose Cooperative (SOBAGROMCO) and in Tupi, South Cotabato by the Sta Teresita Multi-Purpose Cooperative. Both cooperatives are using the different natural farm inputs and have made modifications suitable for their conditions. The proximate analysis of the fermented inputs in SOBAGROMCO is given below. The rate of application depends on the soil analysis and target banana yields. In Toril, Davao City for Bungulan, the fertilization protocol is as follows: Basal application- 3kg compost, 2kg vermi compost Side dress- 20kg compost/6 months, 2kg vermicompost/3 months Soil drench (Hinubig)- FAA, FPJ, FFJ, IMO at 60 ml/mat/month (pure) 2. Organic Pineapple Among the HVCs, pineapple is probably the most difficult to grow organically specially for variety MD-2, which is the favorite variety for fresh pineapple for export. In organic pineapple production, FPJ and FFJ are being used as source of nutrients in addition to vermicompost and seaweed extract. The material for FPJ started with the use of swamp cabbage and muscovado sugar. But FPJ yield is low and cost is high. The material being used now is banana pseudo stem with molasses instead of muscovado sugar. The other materials being used include wild sunflower and lemon grass which is also being used for pest control. The materials for FFJ includes banana and pineapple. They have also made an improvised press to facilitate the extraction of the liquids. 3. Organic Vegetables Bacolod In Bacolod City, the organization that is pushing forward organic agriculture is the Negros Island Sustainable Agriculture and Rural Development Foundation Inc. (NISARD). Established as a result of a Memorandum of Agreement between the provinces of Negros Oriental and Negros Occidental, NISARD, is a non-stock non-profit foundation organization. Among the crops being produced organically by the members are lettuce, tomato, herbs, beans, sugarcane, banana and citrus (calamansi). Among the fermented farm inputs being used are FPJ, FFJ, Caphos, seaweed extract. An assorted of raw materials are being used as substrate for FFJ and FPJ. Bayawan City In Bayawan City, Negros Oriental, the LGU itself is producing the natural/organic farm inputs. They collect the vegetable trimmings and over-ripe fruits from the market for FPJ and FFJ. Fish trashes are also collected from the market for FAA and they use LABS to minimize the foul smell in the FAA. The farmers make CaPhos using both egg shell and shells of the golden snail. These products, FPJ, FFJ, FAA and CaPhos are sold to farmers at PhP 50/liter. Preparations in Bayawan City for the fermented farm inputs has a slight variation in that water is used in both FPJ and FPJ, generally at about 30% by weight. Surallah, South Cotabato The organic farmers in the Municipality of Surallah are being assisted by The Don Bosco Foundation for Sustainable Development, Inc. (DBFSDI), formerly the DonBosco Diocesan Youth Center, Inc. (DBDYCI). The basic production system is based on Biodynamic Farming but parts of KNF are also being practiced as well as Agnihotra. Agnihotra is a healing fire from the ancient science of Ayurveda. It is a process of purifying the atmosphere through a specially prepared fire performed daily during sunrise and sunset. It heals the environment and is being used for gardening and farming. For fruits and vegetables FPJ, FFJ and CaPhos are also being used. Looking Forward While these fermented farm inputs have been adopted by many organic farmers and the number is increasing, the academe has been slow in integrating these in their research and development agenda in improving production systems, largely content mainly on the elemental and inorganic chemistry of nutrient and pest management. Use of the natural inputs is sometimes regarded as unscientific. But science is actually just catching up. Several government agencies and universities are slowly warming up to organics in general and are now including the natural farm inputs in their research and development programs as well as in extension. However in research, there is still the tendency to just `evaluate' and `confirm' the effects of FPJ and FFJ, etc. The research should be at a higher level to contribute positively to the improvement of these natural farm inputs. These can be through the use of locally available plant materials with specific growth promoting effects or addition of other naturally occurring materials/micro organisms to enhance specific effects. An intriguing possibility is the integration of the preparation of natural farm inputs with the concepts in Biodynamic Farming. Such integration will not only enhance organic or biodynamic farming but will also remove the barriers of jargon and perception of exclusivity. Although these preparations can be easily made by farmers themselves, it would also help more farmers if the preparations can be made commercially available. While some LGUs are already investing on these, the numbers are still too few. Several members of the private sector have also started investing on these natural farm inputs. But a few failed because of some technical problems on product shelf life and efficacy. Government support in such undertakings can help a long way in pushing this system of production so that agriculture can regain the lost virginity of the soil and purity of the environment.

Philippines’ biggest hybrid rice seed firm SL Agritech Corp. (SLAC) is targeting the planting of hybrid rice on two million hectares in five years in its aim to help boost Philippines’ rice sufficiency and potential rice export. staple food As the agriculture/" title="View all articles about Department of Agriculture here">Department of Agriculture (DA) aims to hit 22.73 million metric tons (MT) of paddy rice production by 2016 based on its Food Staples Sufficiency Program (FSSP), SLAC is aligning its targets with it. “In three to five years, SLAC is aiming to feed 50 million people. By that time two million hectares must be planted to SLAC hybrid rice varieties,” said SLAC Chairman Henry Lim Bon Liong. Convenors of the First Hybrid Rice Congress in the Philippines held in April this year supports the FSSP program that allocates some 400,000 hectares for hybrid rice by 2014. By 2015 to 2016, this area is foreseen to grow to 500,000 hectares. As SLAC supports DA’s FSSP target to also expand production of other staples like banana, cassava, sweet potato, and corn, SLAC believes rice will remain to be the staple of many Filipinos. Providing for hybrid rice expansion will be a major answer to meeting sharply increasing food demand that may result in any food shortage. SLAC’s specific target is to plant hybrid rice on 500,000 hectares. “If 500,000 hectares are planted to hybrid rice, this can give an incremental yield of three to four tons per hectare. That would equate to an additional two million tons of paddy rice. At 65 percent milling recovery, this can feed 10 to 13 million people at 100 kilo per capita consumption,” said Lim. Higher income SLAC has been part of the Aquino government’s rice export program which is hoped to enable Filipino farmers to earn higher from rice planting. The export program involves export only of premium quality rice, bringing an export price of at least $1,000 per MT compared to just around $500 per MT for regular rice. As hybrid rice gives a high average yield of 7.5 MT per hectare compared to inbred’s four MT, farmers also benefit significantly from higher income. His income can reach a net of P50,000 to P100,000 per hectare. Inbred rice farmers only earn a net of P15,000 to P30,000 per hectare. Of the estimated 400 MT rice export for the year, SLAC accounts for more than 100 MT of the rice shipped to Dubai, Singapore, and the United States. The company has been partnering with local government units, including Cagayan, Bohol, Isabela, and Nueva Ecija in the aim to raise hybrid rice production. In order to achieve its five-year target, SLAC is entering into Private Public Sector Partnership or PPP. It is collaborating with private seed companies, traders and millers, input providers (fertilizer and pesticide suppliers), credit and insurance providers, and DA agencies. SL-8H areas Lim said SLAC would not want the Philippines to be left behind in the global hybrid rice technology’s progress. This is amid SLAC’s own leadership in hybrid rice industry in South East Asia. SL-8H seeds are targeted to planted on 410,000 hectares outside of the Philippines. These are 150,000 hectares, Bangladesh; 200,000 hectares, Indonesia, and 60,000 hectares, Vietnam. The country’s hybrid rice area peaked to 360,000 hectares in 2005 at the height of the hybrid rice seed subsidy program of the government. However, in 2011, when the subsidy was removed, hybrid rice area declined to 180,000 hectares. While the Philippines was among Southeast Asian pioneers in hybrid rice technology since this was introduced early in the last decade, the country is now third from the last among eight identified countries. The biggest hybrid rice areas as of 2011 were in India, two million hectares; Bangladesh, 700,000 hectares; Indonesia, 650,000 hectares; Vietnam, 595,000 hectares; United States, 439,000 hectares. The last three countries (and continent) were Philippines, 180,000 hectares; Myanmar, 78,000 hectares; and Latin America combined, 70,000 hectares. FSSP The FSSP set a target area for the planting of high quality hybrid seeds plus nitrogen. This is 250,000 hectares for 2013, 400,000 hectares for 2014 and 500,000 hectares for 2015-2016. From a target of 20.04 million MT in paddy rice production for 2013, DA’s FSSP has targeted rice production to increase to 21.5 million MT in 2014, 22.13 million MT in 2015, and 22.73 million in 2016. Targeted area from irrigated system (where hybrid rice is mostly grown) is 16.3 million MT in 2013, 17.78 million MT in 2014, 18.37 million MT in 2015, and 18.9 million MT in 2016. From non-irrigated ecosystems, it will be 3.75 million MT in 2013, 3.72 million MT in 2014, 3.75 million MT in 2015, and 3.83 million MT in 2016. National yield average is projected to increase from 4.23 MT per hectare in 2013, 4.43 MT per hectare in 2014, 4.48 MT per hectare in 2015, and 4.53 MT per hectare in 2016. Target area for high quality inbred seeds plus nitrogen including those that will use Integrated Crop Management is 742,500 hectares in 2013, 937,500 hectares in 2014, 1.137 million hectares in 2015, and 1.237 million hectares in 2016. Dona Maria In its own contract growing arrangements for the Dona Maria Premium Quality Rice, SLAC also plans to expand in Visayas and Mindanao. These two major islands have high potential growth with the urbanization of major cities like Iloilo, Bacolod, Dumaguete, Tacloban, Davao,and General Santos. SLAC’s top yielder-farmers have demonstrated that SL-8H can be a far superior rice variety than inbreds. Its highest yielding farmers’ records are 17.28 MT per hectare, Severino Payumo, Nueva Ecija; 17.2 MT, Aida Badong, Camarines Sur; 14.57 MT, Freddie Dalisay, Occidental Mindoro; and 14.02 MT, Severino Velasquez, Nueva Ecija. ### For any questions, kindly contact Ms. Joh Dungca (SLAC), 09175586508; for interview requests, Ms. Analiza C.

The Ecosystems Research and Development Bureau of the Department of Environment and Natural Resources (ERDB-DENR) will hold the Second ASEAN Congress on Mangrove R&D with the theme “Sustainable Management of Mangroves in the course of Climate Change”.

The conference comes in light of evidence that mangroves are proven to reduce the impact of disasters.

“Mangrove habitats represent both a vulnerable resource and a potential deterrent to the effects of climate change. Sea level rise poses a major threat to mangrove ecosystems as it induces erosion and weakening of root structures, increased salinity, and mangrove inundation,” according to ERDB.

Mangroves have been recognized to play an important role in combatting storm surges as what has been observed to be severely destructive during the Yolanda typhoon.

“Mangroves are also known to attenuate waves by as much as 75% through its vast underground root networks and high vegetation structural complexity,” according to “Storm Surge Reduction by Mangroves” authored by a team led by Anna L. Mclvor.

Dr. Henry A. Adornado, ERDB Director, said that the Congress will serve as an avenue for the sharing of best practices on mangrove conservation and plantation management among the ASEAN countries.

We will strengthen collaboration and linkages among environment researchers who are now playing a crucial role in this big task of managing the coastal resources and climate change” Adornado said.

Mangrove practitioners, government officials, scientists, and academicians who have conducted research in the ASEAN region will convene to discuss the following major themes: 1) mangrove Ecology, Functions, and Fisheries, 2) Mangrove Restoration and Rehabilitation, 3) Climate Change Adaptation and Mitigation, and 4) Valuation and Socio-economic studies.

Coastal disasters have occurred as a result of tropical cyclones, tsunamis, landslides, and storms among which are Haiyan (Yolanda) in the Philippines and Tropical Cyclone Komen that caused deaths in the Bay of Bengal affecting Myanmar, India, and Bangladesh in 2015.

“Five hundred sixty three (563) million people in Southeast Asia are concentrated along coastlines measuring 173,251 kilometers long, leaving it exposed to increasing risks including coastal erosion due to climate change and sea level rise,” according to ERDB.

Mangroves are known to protect communities for as long as these have an extent of one kilometer.

"General MacArthur, Eastern Samar, had only less than 100 people died (from Yolanda) due to the mangroves in the area which served as barrier against storm surge,” according to “Saved by the Mangroves:  A Philippine town dodges Haiyan’s storm surge.”

Disaster prevention has become a primary program of ASEAN countries with reports of trends on rising temperature in the region by 1-0.3 degrees Celsius per decade from 1951 to 2000 as reported by the Intergovernmental Panel on Climate Change or IPCC.

With warmer temperature comes higher sea levels.

“Rainfall has been trending down and sea levels up (at the rate of 1–3 millimeters per year), and the frequency of extreme weather events has increased: heat waves are more frequent,” according to ERDB.  (Growth Publishing for ERDB)


Japanese agency adopts BAR’s Edible Landscaping program

A Japanese humanitarian agency has adopted Bureau of Agricultural Research’s (BAR) edible landscaping (EL) program that encourages home-based organic vegetable planting to help reduce imports, enhance the environment, and raise food security. The EL, a partnership between BAR and University of the Philippines Los Banos (UPLB), has generated adopters including the Organization for Industrial, Spiritual, and Cultural Advancement (OISCA) of Japan. Its aesthetic value and food security aims are hoped to have a significant impact locally. edible landscaping “Edible landscaping may not be totally for commercial profitability. But it will raise consumption of vegetables and enhance food security. And we have an organic growing system that’s good for health and environment,” according to UPLB EL Project Leader Farnando C. Sanchez Jr. BAR had budgeted P1 million for the first phase of the technology promotion of EL which initially had its site at the UPLB CA-Agripark. “Instead of planting just ornamental plants, we want to encourage more households to plant vegetables in their front and back yards so we may provide for our homes’ basic needs, and we may be able to reduce our imports of vegetables,” said BAR Director Nicomedes P. Eleazar. A United Nations data quoted by the Factfish indicated that as of 2012 the Philippines had vegetable imports of $3.013 million (P142 million). This project can have extensive livelihood opportunity wherever people want to keep healthy and eat fresh, organic vegetables. “It offers an opportunity for about 34.2 percent of the total household population or 5.2 million families of the country that live below the poverty threshold especially for families in the cities that cannot afford the high cost of basic needs as food,” according to a BAR-UPLB report. Value addition OISCA, a Tokyo-based organization established by Rev. Yonosuke Nakano, has already been engaged in vegetable planting even before it took up EL. Its EL farm is in Tiaong, Quezon. OISCA had a value addition in its vegetable farming from BAR-UPLB’s EL as the beautification function of its farm enhances attraction of young farmers into agriculture. EL also enhances the environment as the greeneries avert emission of more carbon dioxide that contributes to global warming and climate change. When it was founded in the Philippines in 1961, OISCA’s aim was to bring Japanese agriculturists to the Philippines to train Filipinos on agriculture. OISCA as of 1983 had sent 336 Japanese agricultural experts to the Philippines and 245 Filipinos to Japan. The EL’s two phases were implemented from November 2009 to September 2012. Economic value Aside from potentially helping reduce the country’s vegetable imports, the EL has economic value for agritourism. Agritourism sites can charge visitors an entrance fee. One agritourism model is that of the Benguet State University (BSU) which generates around P2 million yearly from its tourist site in its campus in Benguet. It is planted with organic strawberry and Arabica coffee. BSU charges P50 per entrant. Aside from OISCA, the EL of BAR-UPLB has been demonstrated in the gardens of several institutions. These include a Rotary Club of Los Banos-assisted public school, UP Rural High School, and even at BAR’s own office site on Visayas Avenue, Quezon City. Since EL was introduced by UPLB in 1999, EL was also adopted by a Laguna provincial program called “Food Always in the Home” which popularized vegetable gardening. “Sooner some private companies adopted the same concept for their model nurseries. A real estate developer incorporate dthe concept for its farm lot subdivision in Tarlac, “ according to the BAR-UPLB’s “Technology Promotion and Commercialization of Edible Landscaping” (TP-CEL). In Antipolo, in an aim to orient children who are now mostly ignorant on agriculture, a resort has also used edible landscaping as a better alternative to planting ornamental plants. The concept of EL was presented at the Flora Filipina Conference in Manila in January 2009. Malnutrition BAR has been supporting projects that boost consumption of vegetables in the country which is known to be among the lowest in Asia. The World Health Organization (WHO) indicated the Philipines’ vegetable consumption of 60 kilos per person per year in 2007 was one of Asia’s lowest, reported the UN Office for the Coordination of Humanitarian Affairs This results in chronic malnutrition especially in children with shortage in people’s intake of vitamins and minerals. The National Nutrition Survey (NNS) of 2008 reported 33 percent of Filipino children less than 10 years old were too short for their age classification. Stunting also affects 29 percent of five-year-olds. NNS reported the Philippines’ average daily consumption per person of 110 grams of vegetables as of 2008 was lower than the 145 grams consumption in 1978. Furthermore, consumption of fruits was also lower as of 2008 at 54 grams per person per day compared to 104 grams in 1978. BAR and the Department of Agriculture previously had campaigns on raising Philippines’ vegetable consumption. One of these was the “Oh My Gulay” which was implemented with the East and Southeast Asia of the World Vegetable Centre (AVRDC) based in Taiwan. This program aimed to support health programs on reduction of incidence of vitamins and minerals that are linked to contraction of heart diseases, cancers, diabetes, and other degenerative disease. The country’s vegetable consumption is even far lower than WHO’s recommendation of 400 grams of vegetables and fruits per person per day or 150 kilos per year. High-priced One of the reasons for low vegetable consumption may be the high price of vegetables. Most vegetables are produced in farflung upland areas like Baguio and Nueva Vizcaya so that most urban residents do not have access to affordable vegetable. “Vegetables and fruits can be more expensive than fish in the Philippines, and their prices fluctuate a lot,” according to Sheila Aclo de Lima of the AVRDC. “With these (space-friendly) methods (like container farming), underprivileged families can produce for themselves, and their vegetable and fruit consumption is resilient to weather and food crises.” Design The EL project is not only about how to grow organic vegetables but on planning, design, and implementation of a landscape architecture program. “Edible plants can provide the texture, color, and mass that we like to see in our garden as some of them are fine, dainty and lay, bright and attractive, tall growing or in prostate forms,” according to the TP-CEL report. EL farms may have different shapes for the plots rather than just rectangular. These may be shaped as a circle, moon-shaped, square, or heart-shaped. “A trellis does not need to be flat on top. Rather it can be in arch form or tunnel form to inject some novelty and excitement.” An EL farm does not have to be very big. At the UPLB CA AGripark, the technology demonstration area was 2,900 square meters. At BAR’s building, the area only covered 10 by four meters or a total of 40 square meters. A staff member has to be hired to maintain the gardens at the CA AGripark. They have been trained to implement in the EL farms calendared planting, soil amendment, composting, companion cropping or best crop combinations, seedling production, chemical-free or organic vegetable production, and horticultural practices. Pinakbet The CA Agripark had a Pinakbet Garden planted with the vegetables Ilocanos love like eggplant, ampalaya, camote. It had a Sinigang Garden planted with radish, okra, eggplant, tomato, gabi, and kangkong. It had a Kamote Kaleidoscope with different kamote varieties of different colors and interesting shapes, and Salad Republic (lettuce, tomato, chives, celery, chicharo and onion). A Fruit Tree Miracle garden had miracle fruits like kalamansi, guava, chico, kalamias, and papaya. The Herbs Garden had basil, tarragon, mint, viola, oregano, gainura, and gotokola. Urban gardening or container gardening is encouraged in EL so that city dwellers may take advantage of the technology. Any commercially available recyclable plastic container, clay pots, coconut shells, and other commonly available materials were used as pots to demonstrate to many that one does not have to have rich resources to put up this garden. Those planted in these containers are lemon grass, gainura, lettuce, mustard, and pechay. To enhance beautification, the perimeter fence at CA AGripark was planted with different vines like ampalaya, upo, patola, cucumber, and singkamas. Factors Factors to consider in the choice of plants are nutrition, preference, color, texture, scent and attractive physical characteristics. While one expects to see mostly plants in EL particularly vegetables (called softscapes), hardscapes are needed to beautify an EL farm. These are trellises, signage, pots and containers, waterfalls, and lights. The TP-CEL had listed several indigenous fruit trees in the country that have potential use for EL. These are abiu, alingaro, ambarella, araza, ardisia, bago or melinjo, batuan, bitungol, black palm, Brazil cherry, chico-mamey, eleagnus, galo, guava, mulberry, Indian, Philippine chestnut, pitomba, and raspberry bush, among others. Versatile While one initially thinks EL may have limited applications, as he investigates he is surprised that it has vast applications. It includes that for home, commercial, and humanitarian purposes. It can be in homes, parks, schools, business and government offices, and industrial sites. Instead of chemical fertilizers, organic fertilizers are recommended in EL sites. To repel some types of insects, marigold, onion, and garlic are planted around the garden such a on walkways or around perimeter walls. Some insects are also repelled with the use of chili and soap sprayed on plants. Bagging of fruits using paper, plastic, and other innovative materials is encouraged to prevent infestation. Pruning or thinning out of flowers, fruits, and leaves not only enhances plant shape but also its fruiting productivity. Ratooning, retaining the plant from new emerging roots, is also practiced as it saves replanting and fast growth compared to growing plants from new seeds. Kangkong is one of those that are being rationed. Commercial farms aim to harvest massive plants at the same time in order to achieve economies of scale. However, EL is ideal for staggered harvesting which is ideal for small consumption in families. ### (BAR Press Release) Image: bar.gov.ph

Getting familiar with Yambo, an indigenous fruit delight

In a world that is truly rich and diverse in natural resources, new discoveries and breakthroughs take place anytime and anywhere. yambo Segue to agriculture: man continues to discover various flora and fauna that can be used for food or serve other purposes. Older species are being rediscovered with their potential to feed the ever-growing consumer populace. In the Philippines, the agriculture/" title="View all articles about Department of Agriculture here">Department of Agriculture (DA) is now deep in the venture to make the country self-sufficient in food. One approach is through optimizing the production of staples that can supplement rice and through tapping the potentials of other relatively unknown but equally-valuable crops. Before 2013 began, DA Secretary Proceso J. Alcala called on all Pinoys to support our farmers through buying and preparing various indigenous fruits that are healthy and delicious as they celebrate the hope of New Year. One of the indigenous fruits mentioned by the Secretary is the delectable rose apple, locally known as yambo. yambo1 Knowing the native yambo Even though it is widely known as rose apple, yambo is not related at all to the apple fruit. Yambo (Syzygium jambos) belongs to the Myrtaceae family also known as the myrtle family, where other underutilized fruits such as binoloan, dayopod-mabolo, grumichama, eugenia fruits, guava, psidium fruits, jaboticaba, kamanla and tulanan belong. Native to Southeast Asia, yambo was introduced to other regions, where it now bears new names like Malabar plum, plum rose, jambosier, water apple, pommarosa, and pomme rose. The yambo fruit is round to oblong, resembling its close relative, guava. Its thin skin is pale yellow which may or may not have a faint, pinkish pigmentation. Inside, the yellowish flesh is uniquely crisp and doughy and has a sweet, mixed apple and watermelon taste with a rosy flavor which amplifies its rosy scent. The center is a hollow cavity that contains one to four brown, slightly round and hard, rough-coated seeds. When the fruit is shaken, the seeds easily detach, leaving seed coat fragments affixed to the cavity wall. The yambo tree is a small tropical evergreen that grows up to 7.5 to 12 meters tall. When mature, it has a thick canopy of wide-spreading branches and leathery leaves. What’s interesting is that the canopy’s width can exceed the tree’s height, which makes it a good shade provider. Yambo thrives best in tropical to semi-tropical agro-climatic conditions on a loamy type of soil. It can also grow in other soil types such as sand and limestone. The peak season of yambo is between June and September. Like some fruits, yambo is highly perishable and is easily bruised which is why it is not so popular in areas far from where yambo is grown. This characteristic limits the fruit’s marketability and its culinary, industrial, and medicinal potentials . Beneficial uses and functions In areas where yambo is grown, this fruit is popularly consumed as a fresh fruit dessert but it can also be processed into jam, jelly, stews and preserves. The yambo fruit contains protein, iron, fat, carbohydrates, calcium, calories, ash, magnesium, phosphorus, sodium, potassium, carotene, thiamine, riboflavin, niacin, ascorbic acid and fiber which make it a health food. According to research conducted in other countries, yambo is said to be beneficial for the liver and brain as it boosts the vigor of these major organs. The fruit also has a diuretic function while the flower, when sweetened, has the ability to reduce fever. The leaf decoction can be used to relieve sore eyes and rheumatism. Meanwhile, the seeds can aid in dysentery, catarrh (inflammation/irritation of the mucous membrane), diarrhea, and diabetes. However, it has been found that the seeds, roots, stems, leaves and bark contain certain levels of toxic elements, which then require that precautionary procedures be followed before these are further processed and utilized. The essential oil found in the leaves can be distilled and the properties derived can be utilized in the industry of perfume. The brown to dark red heartwood can be used in crafting furniture, boat parts, light structures, packing cases and musical instruments. The yambo tree has flexible branches which can be weaved into baskets and casks. Tapping the potentials of yambo Many Filipinos, just like many people from all over the world, are only aware of the popular typical fruits that are produced in quantity in order to meet escalating demands for these commodities. What we should know is that our country is a bountiful melting pot of various fruit crops, either introduced or native. Our generation and the following generations should know that there are other equally healthy and valuable fruit crops aside from mango, banana, pineapple, and ponkan, among others. The Bureau of Agricultural Research (BAR), as the R&D arm of the DA, will look at the potentials of underutilized fruits like yambo that can thrive well in our lands and can potentially aid in the ultimate goal of “no more hungry Pinoy”. ---------- Sources: 1.

Cabbage (Brassica aleracea L. var. capitatacruciferae) is a leafy green vegetable grown densely-leaved heads. Closely related to other Cole crops such as broccoli, cauliflower and Brussels sprouts, it descends from B. oleracea var. oleracea, a wild field cabbage. Cabbage heads generally range from 1 to 8 pounds (0.45 to 3.6 kg), and are found in green, purple and white. Smooth-leafed firm-headed green cabbages are the most common, but crinkle-leafed savoy cabbages are also found. [caption id="" align="alignnone" width="500"]cabbage photo Photo by RSCJ Photos [/caption] Cabbage is locally known as “repolyo”, grown for its firm, compact, round to flat heads. It belongs to a group of cultivated varieties of the species B. oleracea called “cole crops”. It is the most widely grown crucifer locally.Cabbage ranks as one of the most economically important vegetable crop in the highlands. In the country, an area of 8,502 hectares was planted with cabbage and 123, 443 metric tons of cabbage was harvested in 2007. (BAS) In the Cordillera Administrative Region a total of 5,526 hectares were planted with cabbage and 99,957 metric tons were harvested in 2007(BAS). Cabbage is one of the major cash crops of vegetable producers in the Cordillera and one of the leading vegetable crops in the world. Cabbage, is rich in minerals, specially sulfur compounds and magnesium. It is sometimes used in the treatment of mineral deficiencies and is restores vitality and fitness. It is also effective in calming the nerves and promote relaxation and sleep. It has been recommended as an herbal treatment for hyperthyroidism, headaches, migraines, arthritis, varicose ulcers, constipation, and mineral deficiency. It is a good source of beta-carotene, vitamin C and fiber. It is a cruciferous vegetable, and has been shown to reduce the risk of some cancers, especially those in the colorectal group. This is possibly due to the glucosinolates found in cole crops, which serve as metabolic detoxicants, or due to the sulphoraphane content, also responsible for metabolic anti-carcinogenic activities. Purple cabbage also contains anthocyanins, which in other vegetables have been proven to have anti-carcinogenic properties. Along with other cole crops, cabbage is a source of indole-3-carbinol, a chemical that boosts DNA repair in cells and appears to block the growth of cancer cells. Research suggests that boiling these vegetables reduces their anti-carcinogenic properties. Variety Requirement Pointed head (Scorpio) is preferred over round to flat head in Luzon however, in Visayas and Mindanao flat varieties that are not compact but have long shelf life are preferred. Main Varieties 1. Green Smooth: Ramgo, RV Cross, Scorpio, Rare Ball, Blue Dynasty; It has smooth, green outer leaves and pale interior leaves. 2. Red: Red Acre, Red Dynasty, Red Jewel; Round, compact and heavy for its size, it boasts dark-red thick and pliable shiny leaves. The color of this cabbage has an effect on its slightly peppery flavor. The darker the red, the better the taste. Chefs prize it for adding vivid color to salads and cooked dishes.Red cabbage gets its color because it contains pigment molecules called anthocyanins. These same plant pigments produce red, pink, violet and magenta colors in different parts of several types of plants. 3. Savoy: Curly leaves are the most tender and sweet of the cabbage varieties with a deliciously distinctive flavor; in addition it lacks the sulphur-like odor that is associated with so many cabbage varieties when they are being cooked. Its crinkly leaves are quite pliable and therefore it lends itself very well to making stuffed cabbage. It is tender enough to be eaten raw in salads. A drawback of its tender nature is that it does not have the keeping quality of its sturdier cousins. A week is generally the longest a head of Savoy cabbage will stay fresh in the refrigerator. A good head of Savoy cabbage will be solid in the center, somewhat conical shaped and heavy in relationship to size, with deep blue-green outer leaves and a pale green center.

Climatic Requirement Cabbage grows best in a relatively cool and humid climate but can successfully grow in the lowlands during the cooler months. Leaves are more distinctly petiole and the quality of the head is impaired in drier atmospheres .The delicate flavor is also lost under these conditions. Yield and quality are poor in summer and it is also difficult to control insect pests. The optimum temperatures for growth and development are from 18 °C to 20 °C. It is fairly resistant to frost and can survive temperatures as low as - 3 °C without damage. Cabbage is also adapted to a wide variety of climatic conditions and can be grown throughout the year in most regions. Soil Requirement Cabbage grows well in deep, well drained soils high in organic matter with an optimum pH range from 6.0 to 6.8. The soil also requires Boron and Molybdenum with moisture level not less than 2.5 cm deficit. Culture and Management 1. Sowing of Seeds. From 1/5 to 1/4 kg. of seeds is required per hectare. For limited scale of gardening, seedlings are raised in seed boxes, containing soil rich in humus and free from diseases and other harmful soil organisms. In extensive gardening like in Benguet Province, farmers grow seedlings in variant beds provided with a portable glass or plastic roofing's. The beds are watered with a solution of ammonium sulphate (3 to 4 tablespoonfuls ammonium sulphate dissolved in one kerosene can of water) to serve as starter. The optimum age of seedlings for transplanting ranges from 25 to 35 days after sowing. “Hardening” is essential to reduce high mortality and cost of replanting. This is achieved by suspending irrigation of the beds a few days before transplanting. 2. Soil Preparation. The planting area should be cleaned from weeds or debris from previous crop before planting. If the land is being operated for the first time, it should be plowed twice or dug twice for a two-week interval to minimize and control weed growth. 3. Planting. Seedlings should be transplanted as soon as they reach the desired size and only well-hardened, young, stocky plants should be used. Transplanting is done on moist soil. The soil around the roots should be firm and irrigated as soon as possible after the seedlings set. In wet areas, cabbage should be planted on raised beds or ridges to reduce water-logging and stem or root rot diseases. After plots/beds have been properly leveled to desire height for (elevated beds) holes should be established spaced with 30-35 cm in rows and 30-35 cm also between rows. Plant only one seedling per hill. During planting, the seedling shoot apex should be higher than the ground level of the bed. Plant population and spacing influence head size, head shape and yield. Cabbage plant populations vary according to the target market for a particular crop. Cabbage forms smaller and slightly more pointed heads when they are spaced closely. It is recommended that large-headed cultivars should be planted 600 to 700 mm apart between rows and 450 mm apart within rows. Smaller-headed varieties are planted 600 X 300 mm apart. 4. Fertilization. Cabbage is a heavy feeder and requires supplemental fertilization in the form of manure or compost, nitrogen, phosphorus and potassium (Animal dung or chicken dung 2-3 tons/ha). Cabbage requires 200 to 250 kg nitrogen per hectare. The first application is made together with phosphorus and potassium. The remainder is side-dressed two to three weeks after transplanting and again three weeks later or applied once at about six weeks. Cabbage also needs micronutrients for proper growth and development. 5. Irrigation. Cabbage should be irrigated immediately after sowing or transplanting. Thereafter, irrigation should be applied at intervals of 10 to 12 days in heavysoils or eight days in light soils and the schedule should be followed until the heads are fully developed and firm. Young plants should receive enough water for vegetative growth before forming heads. Excess moisture when the heads have formed may cause them to crack. 6. Weed control. Weeds are controlled mechanically or by hand as well as chemically through the application of registered herbicides. Mechanical cultivation should be done during land preparation until the plants are about half-grown. The first cultivation should be done two to three weeks after transplanting. 7. Pest and Disease Control a. Aphids (several kinds). Cabbage is attacked by several aphids but the grey cabbage aphid (Brevicorynebrassicae) and the green peach aphid (Myzuspersicae) are the mostcommon. Damage is caused when they suck sap from the plant and contaminatethe edible product. Feeding of the cabbage aphid causes a chlorosis and malformation of the leaf. Natural Enemies. Predators like lady beetles, wasps, spiders, Syrphids, lacewings and some parasitic fungi. Management. Use yellow pan trap and a layer of aluminum foil under plants reflects light to underside of leaves making them an undesirable habitat for aphids. b. Cabbage Butterfly or Cabbage worm (PieresrapaeL). The larva feeds on the leaves by making large holes and leaving several black feces. The old larvae move upward and eat the growing shoot. Natural Enemies.Parasitic wasps like braconids, chalcid, ichneumonids and trichogramma and predators like earwigs, syrphids and spiders. Management. Catch the adults with nets during daytime. c. Cabbage Center Grub (HellularogatalisHulst). It makes holes on the shoots Feeding is concentrated at the heart of young plants or inside a developed head. Natural Enemies.Predators like ants, earwigs, pentatomid bugs, spiders, beetles and syrphids and parasitoids like wasps and nuclear polyhedrosis virus. Management. Trap the adults with light traps during night time. Flooding the soil may also be done to kill the larvae. d. Diamond-black moth (Plutellaxylostella). The larvae make holes on the leaves preferably on the underside and not including the leaf veins. The holes become biggeras the plant grows. Severely damaged crops have skeletonized leaves and fail to produce heads. The larvae also feed on the shoots of young plants. DBM I is the most serious pest of cabbage. Growth and yields can be seriously reduced by heavy infestation. Natural Enemies.Parasitoid wasps like Diadegma and Trichgramma and predators like syrphids, spiders earwigs, ladybeetles’ Trichomalopsis, green and white muscardine fungus disease. Management. Diadegma, is readily available at BPI-BNCRDC and BSU. Release the Diadegma according to the recommendation of the agency where you got the stock. There are Diadegmain the fields where pesticides are not usually used and they should be conserved. To conserve them apply the recommended insecticides only if the average number of DBM larva from 10 plants is two (2) from transplanting to head formation. The use of BT insecticide is recommended so that the Diadegma will not be killed. “Rainbird” irrigation will also prevent the adult diamond back moth tolay eggs on the plants. a. Cabbage looper (TrichoplusianiHubner). Damaged plants show irregularly holes on the veins and midribs of the leaves Natural Enemies Wasps like Apanteles and nuclear polyhedrosis virus parasitize the larvae and another wasp called the Brachymyria sp.Parasitize the pupa. Management 1. Be sure to purchase only clean transplants or raise your own in clean greenhouse settings in order to avoid all three species. 2. Cruciferous weed control. 3. After harvesting early season brassica crops, the crop debris should be tilled into the soil to destroy larvae and pupae that could lead to higher populations on later brassica crops. 4. Trap crops have had variable success. Trap crops are plants that are more attractive to moths for egg laying; however one has to be careful that populations that build up on the trap crop do not spill over to the cash crop. b. Greater cabbage moth (Crocidolomiabinotalis) The larvae spin a thin web over their feeding places. Damage is severe during early attacks when they destroy the growing point of the plants. Natural Enemies. Predators like earwigs, pentatomid bugs and spiders and parasitoid wasps like ichneumonids, braconids and trichgramma. Management. Trap adults with light during night time c. Flea Beetle (Phyllotreta sp.). The adult feeds on leaves by chewing, making many small round holes. They may also feed on stems. The larvae feed on the roots of the plant. Natural Enemies. Earwigs and Carabid Beetles Management. Trap the adults with sticky yellow trap and flooding. d. Leafminer (Liriomyzahuidobrensis Blanchard). The larvae makes serpentine or curled mines on the leaves. The mines start to appear on matured leaves, first on the lower mature leaf then towards the upper leaves as the plant mature. The female adult also makes pinholes on the leaves. Natural Enemies. Wasps such as icheneumonids and braconids including earwigs and short winged beetles. Management. Use yellow sticky traps apart from the cultural management practices. A community wide use of sticky traps is recommended. e. Cutworm (Agrotis spp.). The larvae feeds on the stem as a result the stem is cut. Plants with cut stems fall and dry up during daytime that is why it is easy to determine if there are cutworms in the field. The surrounding soil where the cutworm also stays dry up. Some larvae climb up to the leaves and make holes or bore into developing heads of cabbage. Natural Enemies.Earwigs, spiders, pentatomid bugs and wasps like ichneumonids, braconids and trichogramma. Management. Trap the adults with light during night time. Removal of weeds before planting is also recommended. f. Slugs. The young and adult chew irregular holes with smooth edges on the leaves and they cut young shoots and stems. Look for the silver mucous trails to confirm damage caused by slugs. Natural Enemies. Ground beetles, frogs birds and lizards Management. Trap the adults by placing fermented substance like beer in shallow containers at night near the bottom of the plants to attract, drown and kill the adults. Adding molasses or flour will make the trap attractive to slugs. g. Nematodes. Plants are stunted and there is premature wilting and slow recovery to improved soil moisture conditions, leaf chlorosis (yellowing) and other symptoms characteristic of nutrient deficiency. Plants exhibiting stunted or decline symptoms usually occur in patches of non-uniform growth rather than as an overall decline of plants within an entire field. Root symptoms induced by root-knot may cause swollen areas (galls) on the roots of infected plants. Gall size may range from a few spherical swellings to extensive areas of elongated, convoluted, tumorous swellings which result from exposure to multiple and repeated infections. Management. Control measures such as crop rotation, using resistant cultivars, cultural and tillage practices and use of transplants, and preplantnematicide treatments. Damping off (Altenaria spp., Rhizoctoniasolani, Pythium spp.).Infected seedlings wilt, turn purple and die, and often have no lateral roots. Management • Use treated seed • Sterilize the seedbed before planting • Remove infected plants when symptoms appear h. Sclerotonia rot or white mold (sclerotiniasclerotiorum.). The disease is favored by cool, wet conditions and it can survive for two to three years in the soil. Above-ground parts of infected plants may be covered with a white cottony growth. The tissue beneath the mould turns soft and watery. Management • Crop rotation • Plant on ridges or raised beds • Remove and destroy infected crop residues • Good water management aimed at keeping the soil dry • Avoid using susceptible annual legumes as cover crops. • Control broadleaf weeds. • Promote air circulation by increasing row spacing. • Maintain proper nitrogen fertilization. i. Clubroot (Plasmodiophorabrassicae.). The disease is soil-borne and the spores can survive for up to 20 years in the soil. It is most severe on acid soils or moderate pH soils that are poorly drained or have high clay content. Infected plants are characterized by stunting, wilting and purpling of leaves. The roots change into a mass of large, elongated or rounded swellings or clubs. The clubs rot and form bad smelling wet masses Management 1. Practice sanitation 2. Crop rotation 3. Grow transplants in fumigated beds 4. Apply lime n. Fusarium wilt or cabbage yellows (Fusariumoxysporumf.conglutinans). Fusarium wilt is more prevalent in summer and the fungus persists indefinitely in the soil. Initially the symptoms appear as yellow foliage, often mainly on one side of the plant. The leaves become distorted and gradually turn brown and drop prematurely. The vascular area also discolors. Management 1. Planting resistant cultivars 2. Plant on soils free of disease 3. Soil fumigate before planting 4. Crop rotation 5. Practice sanitation o. Black rot (Xanthomonascampestris). The disease is introduced to fields in seed and its spread is very rapid under hot, rainy, windy conditions. The disease survives for three to five years in fields and in the stems of host plants. The symptoms first appear as yellow to light brown patches at the margins of leaves and later a network of black veins develops within these areas. Affected areas turn brown and dry out and often leave a characteristic triangular-shaped lesion on the leaf margin, with one point of the triangle directed towards the midrib. Older infected leaves also drop and the vascular tissue turns brown as the bacteria move into the main veins and vascular system. Plants infected at the seedling stage may die or remain stunted. Management 1. Plant resistant cultivars 2. Use disease-free seed or seed treated with hot water 3. Crop rotation 4. Control cruciferous weeds 5. Avoid the use of sprinkler irrigation 6. Increase the interval between irrigation 7. Deep-ploughing of all infected plant material p. Downy mildew (Peronosperaparasitica). Downy mildew is common in cool, humid weather. The fungus survives in debris and is spread by air-borne spores in large numbers. Infected leaves appear as if they have been lightly sprinkled with pepper. The leaves become yellow around the pepper spots. Lesions merge to cover large areas of leaves. Fine, fluffy white mould appears on the lesions on the underside of the leaf during humid conditions. Management 1. Plants should not be irrigated after 3:00 pm and before 10:00 am. 2. Treat seedlings with fungicides. 3. Fumigate the seedbed. 4. Good seedbed preparation. q. Black leg (Phoma lingam). Black leg is seed-borne and it can infect the whole seedbed when an infected seed germinates. The whole plant wilts when infected. White to light brown lesions with a purple to black margin develop on the stem and on leaves. The lesions have small black dots in the centre. The centre of the lesion gets woody and cracks. Management 1. Use seedlings grown in seedling boxes. 2. Fungicide treatment of seedbed. 3. Seedbeds should be situated far from old production fields. 4. Seedbed should be destroyed if leaf lesions are found. 5. All cabbage material remaining in seedbeds should be removed. 6. Removal of cruciferous weeds from production fields. 7. All debris should be removed after harvesting. r. Cabbage Soft Rot. Leaves turn yellow (chlorotic) beginning at margins and spreading inwards. Veins within area are turn. Infections enter main stem turning the inside black. Plants either die or are dwarfed when young, become defoliated if more mature. Management. Plant resistant varieties and rotate crops from year to year. s. Bacterial leafspot (Pseudomonas syringaepv. maculicola). Bacterial leafspot is more severe in cool, moist weather. The symptoms initially appear as small, faint, water-soaked areas on the underside of leaves. The affected areas develop into brownish to purplish grey necrotic spots, fairly irregular after a few days. They may coalesce to form large irregularly shaped spots. The leaf becomes wrinkled and the tissue may tear when the lesions are many. Management 1. Chemical control. 2. Plant resistant cultivars. 3. Use disease-free seed or seed treated with hot water. 4. Crop rotation. 5. Avoid using sprinkler irrigation. 6. Increase the interval between irrigation. 7. Control cruciferous weeds. 8. All infected plant material should be deep-ploughed. t. Alternaria leaf spot (Alternaria spp.). The disease is common during cool, rainy weather. Initially, symptoms appear as small, dark areas and they rapidly enlarge to form large circular lesions that develop a bull’s-eye pattern or target spot. The lesions are dark brown during wet periods. A brown, velvety, spore-bearing growth can be noticed on the older lesions. Management 1. Use disease-free or treated seed 2. Removal of plant refuse 3. Chemical control 8. Harvesting. The crop is harvested when the heads attain their full size and become firm and hard but tender. The color of the head is sometimes used as a maturity index. A fully developed head has a lighter shade of green. If harvesting is delayed, the heads may split and rot while the heads harvested early may be soft. The crop for the fresh market is harvested by hand with a knife or sickle. The heads should be cut off in such a way that a few of the large, open wrapper leaves are left for protection around the heads. Harvesting should be such that bruising of the heads is avoided as this makes them unattractive. Most of the stem should be left on the head if the crop is to be stored. 9. Post-harvest Handling. Harvested produce should always be removed from direct sunlight and transported to the packing shed as soon as possible. Cabbage and leafy greens are particularly susceptible to wilting and other damage from high temperatures. When there is a delay of more than an hour or two between harvest and packing, a water drench or spray arrangement can help prevent dehydration and overheating. 10. Sorting and Grading. The injured leaves should be removed. 11. Packing. Cabbage is packed in mesh pockets or sold loose. 12. Storage. The optimum storage temperature for cabbage is 0 °C and relative humidity of 90% to 95%. Cabbage to be stored should be mature and disease-free and should not have been exposed to prolonged frost or cold. Further trimming may be necessary, mainly to remove the discolored butt upon removal from storage. 13. Transport. Care must be taken such that trucks are not overloaded on the bottom layers of produce, otherwise they will be crushed. Generally, the produce should be covered with a sheet to prevent frosting or desiccation, but on warmer days, when sweating and heating might occur, the sheet should be left off. Utilization 1. An important ingredient of coleslaw or mixed salads. 2. Consumed fresh, cooked, boiled, steamed, stir-fried, pickled or dehydrated. 3. Locally served in pancit, chopsuey, lumpiang sariwa and meat dishes like nilaga and pochero. 4. Used in salad, rolls, sauerkraut or fermented cabbage. 5. Eaten raw before meals in Rome to prevent hang-over. 6. Provide pain relief for breast feeding mothers. 7. Juice used for treatment of ulcer.

Coconut Embryo Culture for the Propagation of Macapuno Seedlings

$

The coconut embryo culture technology is now being successfully applied in the rescue of Makapuno embryos. The Makapuno embryo does not develop normally because the endosperm, which supports the germination of the embryo, is abnormal and rots when the nut matures. The embryo culture technique is the only means known to germinate the Makapuno embryo to produce a pure bearing Makapuno palm. Successfully grown Makapuno palms produce from 75-100% Makapuno nuts if planted together and/or isolated from other coconut palms by a pollen barrier. In contrast, palms grown from normal nuts of a Makapuno-bearing palm can produce only 2-20% Makapuno nuts because they are heterozygous for the Makapuno character. With financial assistance from PCARRD/DOST, several embryo culture satellite laboratories have been established to mass produce Makapuno seedlings for interested coconut growers. These are located in Albay, Pangasinan and Cavite (in Luzon), Leyte (in the Visayas) and Davao and Zamboanga( in Mindanao).

The pineapple also known botanically as Ananas comosus plant is a terrestrial herb 2 1/2 to 5 ft (.75-1.5 m) high with a spread of 3 to 4 ft (.9-1.2 m); a very short, stout stem and a rosette of waxy, straplike leaves, long-pointed, 20 to 72 in (50-180cm) 1ong; usually needle tipped and generally bearing sharp, upcurved spines on the margins. pineapple Four major varieties of pineapples: • Smooth Cayenne • Queen Victoria • Red Spanish • Pernambuco Several varieties of pineapple are available in the Philippines. One is the Smooth Cayenne or Hawaiian, which is the heaviest, most popular, and best for canning. The Queen or African Queen or Formosa is the sweetest. The Native Philippine Red or Red Spanish is cone-shaped and considered of medium quality. It is also grown for its fiber. The Cabezona is the largest, measuring approximately 8-12 inches long when fully matured. Other varieties include the Buitenzorg or Java, Sugar, Loaf and Abakka. Climate The pineapple is a tropical or near tropical plant limited (except in greenhouses) to low elevations between 30°N and 25°S. A temperature range of 65°-95°F (18.33-45°C) is most favorable, though the plant can tolerate cool nights for short periods. Prolonged cold retards growth, delays maturity and causes the fruit to be more acid. Altitude has an important effect on the flavor of the fruit. Between 4500 and 5700 ft (1371-1738 m) the flavor is most suitable for canning. The pineapple is drought tolerant and will produce fruit under yearly precipitation rates ranging from 25 to 150 in (650-3,800 mm), depending on cultivar and location and degree of atmospheric humidity. Soil The best soil for pineapple culture is a well-drained, sandy loam with a high content of organic matter and it should be friable for a depth of at least 2 ft (60 cm), and pH should be within a range of 4.5 to 6.5. Soils that are not sufficiently acid are treated with sulfur to achieve the desired level. The plant cannot stand waterlogging and if there is an impervious subsoil, drainage must be improved. Pure sand, red loam, clay loam and gravelly soils usually need organic enrichment. Filter presscake from sugar mills greatly enhances plant vigor, fruit yield, number of slips and suckers. Propagation Most beginners start pineapple growing by planting the tops of shop bought pineapples. However, it's a slow way to grow pineapples. Tops take at least 24 months to flower, and then it takes another six months for the fruit to mature. Suckers and slips grow up and fruit a lot quicker. Suckers are little plantlets that grow between the leaves of the mature pineapple. Slips are the tiny plantlets that grow at the base of the fruit on the fruit stalk. Culture The land should be well prepared at the outset because the pineapple is shallow-rooted and easily damaged by post-planting cultivation. Fumigation of the soil contributes to high quality and high yields. Planting: In small plots or on very steep slopes, planting is done manually using the traditional short-handled narrow-bladed hoe, the handle of which, 12 in (30 cm) long, is used to measure the distance between plants. Crowns are set firmly at a depth of 2 in (5 cm); slips and suckers at 3 1/2 to 4 in (9 10 cm). Butts, after trimming and drying for several days, are laid end-to-end in furrows and covered with 4 in (10 cm) of soil. Double-rowing has been standard practice for many years, the plantlets set 10 to 12 in (25 30 cm) apart and staggered, not opposite, in the common rows, and with 2 ft (60 cm) between the two rows. An alley 3, 5 1/2 or 6 ft (.9, 1.6 or 1.8 m) wide is maintained between the pairs, allowing for plant populations of 17,400, 15,800 or 14,500 per acre (42,700, 37,920 or 33,800 per ha) respectively. Close spacing gives highest total crop weight—e.g.. 18,000 plants/acre = 28.8 tons (43,200 plants/ha = 69.12 tons). However, various trials have shown that overcrowding has a negative effect, reducing fruit size and elongating the form undesirably, and it reduces the number of slips and suckers per plant. Some plantings are mulched with bagasse. In large operations, asphalt-treated paper, or black plastic mulch is regarded as essential. It retards weeds, retains warmth in cool seasons, reduces loss of soil moisture, and can be laid by machines during the sterilization and pre-fertilization procedures. Mulch necessitates removal of basal leaves of crowns, slips and suckers and the use of a tool to punch a hole at the pre-marked planting site for the insertion of each plantlet. The mulch is usually rolled onto rounded beds 3 1/4 ft (1 m) wide. Mechanical planting: Research on the potential of machines to replace the hard labor of planting pineapples was begun in Hawaii in 1945. A homemade device was first employed in Queensland in 1953. Early semi-mechanical planters were self propelled platforms with driver and two men who made the holes in the mulch and set the plants in place. With a 2-row planter, 3 men can set 7,000 plants per hour of operation. Frequent stops are necessary to reload with planting material. With improved equipment, mechanical planting has become standard practice in large plantations everywhere. The most sophisticated machines have attachments which concurrently apply premixed fertilizer and lay a broad center strip of mulch, set the plantlets along each edge, and place a narrow strip along the outer sides. The only manual operation, apart from driving, is feeding of the plantlets to the planting unit. With this system, up to 50,000 plants have been set out per day. Fertilization: Nitrogen is essential to the increase of fruit size and total yield. Fertilizer trials in Kenya show that a total of 420 lbs N/acre (471.7 kg/ha) in 4 equal applications during the first year is beneficial, whereas no advantage is apparent from added potassium and, phosphorus. Puerto Rican studies have indicated that maximum yields are achieved by urea sprays supplying 147 lbs N/acre (151 kg/ha). In Queensland, total yield of mother plants and ratoons was increased 8% by urea spraying. Normal rate of application is 3 1/2 gals (13.3 liters) per 1,000 plants. On acid Bayamon sandy clay in Puerto Rico, addition of magnesium to the fertilizer mix or applying it as a spray (300 lbs magnesium sulfate per acre—327 kg/ha) increased yield by 3 tons/acre (7 tons/ ha). On sloping, stony clay loam high in potassium, Queensland growers obtained high yields of 'Smooth Cayenne' from side dressings of NPK mixture 5 times a year. On poor soils, nitrogen and potassium levels of the plants may become low toward the end of the crop season. This must be anticipated early and suitable adjustments made in the application of nutrients. Potassium uptake is minimal after soil temperatures drop below 68°F (20°C). On fine sandy loam in Puerto Rico, the cultivar 'P.R. 1-67' performed best with 13-3-12 fertilizer applied at the rate of 1.5 tons/acre (3.74 tons/ha). In this expertmeet, 13,403 plants/acre (32,167/ha) produced 9,882 fruits/acre (23,717/ha), weighing 31.28 tons/acre (75 tons/ha). In Venezuela, 6,250 medium-size fruits per acre (15,000 fruits/ha) is considered a very good crop. Fruit weight has been considerably increased by the addition of magnesium. Fruit size and total yield have been enhanced by applying chelated iron with nitrogen; also, where chlorosis is conspicuous, by accompanying nitrogen with foliar sprays of 0.10% iron and manganese. Some growers thin out suckers and slips to promote stronger growth of those that remain. Irrigation: Irrigation is desirable only in dry seasons and should not exceed 1 in (2.5 cm) semi-monthly. Weed Control: Manual weeding in pineapple fields is difficult and expensive. The use of paper or plastic mulch and timely application of approved herbicides are the best means of preventing weed competition with the pineapple crop but the use of coir dust has a deleterious effect on the crop, delaying or preventing flowering. Flower Induction: Pineapple flowering may be delayed or uneven, and it is highly desirable to attain uniform maturity and also to control the time of harvest in order to avoid overproduction in the peak periods. In 1874 in the Azores it was accidentally discovered that smoke would bring pineapple plants into bloom in 6 weeks. The realization that ethylene was the active ingredient in the smoke led to the development of other methods. As far back as 1936, compressed acetylene gas, or a spray of calcium carbide solution (which generates acetylene) were employed to expedite uniform blooming. Some growers have merely deposited calcium carbide in the crown of each plant to be dissolved by rain. A more advanced method is the use of the hormone, a-naphthaleneacetic acid (ANA) or B naphylacetic acid (BNA) which induce formation of ethylene. In recent years, B-hydroxyethyl hydrazine (BOH) came into use. Treatment is given when the plants are 6 months old, 3 months before natural flowering time. The plants should have reached the 30 leaf stage at this age. Spraying of a water solution of ANA on the developing fruit has increased fruit size in 'Smooth Cayenne' in Hawaii and Queensland. In West Malaysia, spraying 'Singapore Spanish' 6 weeks after flowering with Planofix, an ANA-based trade product, delayed fruit maturity, increased fruit size, weight and acidity. Similar results have been seen after hormone treatment of 'Cayenne Lisse' on the Ivory Coast. Trials with 'Sugarloaf' in Ghana showed calcium carbide and BOH equally effective on 42-to 46-week-old plants, and Ethrel performed best on 35-to 38-week-old plants. 'Sugarloaf' seems to respond 10 days earlier than 'Red Spanish'. Ethrel, or the more recently developed Ethephon, applied at the first sign of fruit ripening in a field will cause all the fruit to ripen simultaneously. It brings the ratoons into fruit quickly. There is a great saving in harvesting costs because it reduces the need for successive pickings. Plants treated with naphthaleneacetic acid produce long, cylindrical, pointed fruits, maturing over an extended period of time, ripening first at the base while the apex is still unripe. Ethylene treatment results in a square shouldered, shorter fruit maturing over a shorter period and ripening more uniformly. Pests Nematodes (Rotylenchulus, Meloidogyne, Pratylenchus, Ditylenchus, Helicotylenchus, and other genera) cause stunting and degeneration in pineapple plants unless soil is fumigated. Mealybugs (Pseudococcus brevipes and P. neobrevipes) attack leaf bases and cause wilt. The leaves turn orange-brown and wither due to root rot. Prevention requires spraying and dusting to control the fire ants (Solenopsis spp. ) which carry the mealybugs from diseased to healthy plants. Control is difficult because there are many weeds and other local plants acting.as mealybug hosts. Some success was achieved in Florida in combatting mealybugs with the parasitic wasp, Hambletonia pseudococciaa Comp., though the general use of insecticides limits the activity of the wasp. The pineapple mite, or so-called red spider (Dolichote-tranychus (or Stigmacus) floridanus (Banks) also attacks leaf bases and is troublesome during prolonged droughts, heavily infesting the slips. The pineapple red scale (Diaspis bromeliae) has been a minor pest in Florida. Since 1942 this scale has spread to many pineapple districts in southeastern Queensland, with occasional serious infestations. Natural predators afford about 40% control. The palmetto beetle (Rhynchophorus cruentatus), which feeds on palm logs, enters the bud and lays eggs in young fruits and the fruit stalk. The sap beetle (Carpophilus humeralis) is one of the main enemies of pineapple fruits in Puerto Rico, Hawaii and Malaysia and is especially attracted to fruits affected by gummosis. Populations have been diminished by sanitary procedures and growing of cultivars resistant to gummosis, and chemical control is being evaluated. In Brazil, larvae of the large moth, Castnia licus, and of the butterfly, Thecla basilides, damage the fruit. The latter is a problem in other parts of tropical America also and in Trinidad. Cutworms eat holes in the base of the immature fruit. Fruit fly larvae do not pupate in 'Smooth Cayenne' but new hybrids lack resistance and may require treatment. In New South Wales, poison baits are employed to combat fruit damage by crows, rats and mice. Rats may eat the base of the stem and destroy ratoons and suckers. Rabbits in winter eat the leaves as high as they can reach. Diseases In Queensland, top rot and root rot are caused by the soil fungi Phytophthora cinnamomi and P. nicotianae var. parasitica which are most prevalent in prolonged wet weather in autumn and winter. Improved drainage helps reduce the risk and monthly spraying with fungicide gives good control. P. cinnamomi may also cause rot in green fruit on ratoons. These diseases are largely prevented by the use of paper or plastic mulch on raised beds. Base rot is caused by the fungus Ceratocystis paradoxa, especially where drainage is poor. The imperfect form (conidial state) of this fungus, known as Thielaviopsis paradoxa, causes butt rot in planting material, also soft rot or breakdown of fruits during shipment and storage. If 1/4-ripe 'Red Spanish' fruits are kept at temperatures between 44.6° and 46.4°F (7°-8°C) while in transit, soft rot will not develop. Fusarium spp. in the soil are the source of wilt. Black heart is a physiological disorder not visible externally, usually occuring in winter particularly in locations where air flow is inadequate. Highest incidence in West Africa has been reported in midsummer. It begins as "endogenous brown spot" at the base of the fruitless close to the core. Later, affected areas merge. It has been attributed to chilling or low light intensity from dense planting or cloudiness. It can be controlled by one-day heat treatment at 90° to 100°F (32°-38°C) before or after refrigerated storage. In 1974, the microorganism Erwinia chrysanthemi was identified in Malaya as the cause of bacterial heart rot and fruit collapse. Yellow spot virus on leaves is transmitted by Thrips tabaci Lind. Black speck and water blister are mentioned among other problems of the pineapple. A condition called Crookneck is caused by zinc deficiency. It occurs mainly in plants 12-15 months old but is also frequent in suckers. The heart leaves become curled and twisted, waxy, brittle, and light yellowish-green. Sometimes the plant bends over and grows in a nearly horizontal position. Small yellow spots appear near the edges of the leaves and eventually merge and form blisters. Later, these areas become grayish or brownish and sunken. Treatment is usually a 1% solution of zinc sulfate. Many growers use a combined spray of 10% urea. 2% iron sulfate and 1% zinc sulfate. If burning occurs. the proportion of urea should be changed to 5%. Excessive use of urea for this or any other purpose can lead to leaf tip dieback and yellowing of older leaves due to the biuret content in urea. Copper deficiency is evident in concave leaves with dead tips and waxiness without bloom on the underside. Sunburn or sunscald develops when fruits fall over and expose one side to the sun, though 'Abacaxi' may sunburn even when erect. Affected fruits soon rot and become infested with pests. They must be cut as soon as noticed and safely disposed of where they will not contaminate other fruits. Dry grass, straw, excelsior or brown paper sleeves may be placed over fruits maturing in the summer to prevent sunburn. Harvesting It is difficult to judge when the pineapple is ready to be harvested. The grower must depend a great deal on experience. Size and color change alone are not fully reliable indicators. Conversion of starch into sugars takes place rapidly in just a few days before full maturity. In general, for the fresh fruit market, the summer crop is harvested when the eye shows a light pale green color. At this season, sugar content and volatile flavors develop early and steadily over several weeks. The winter crop is about 30 days slower to mature, and the fruits are picked when there is a slight yellowing around the base. Even then, winter fruit tends to be more acid and have a lower sugar level than summer fruit, and the harvest period is short. Fruits for canning are allowed to attain a more advanced stage. But overripe fruits are deficient in flavor and highly perishable. Some people judge ripeness and quality by snapping a finger against the side of the fruit. A good, ripe fruit has a dull, solid sound; immaturity and poor quality are indicated by a hollow thud. In manual harvesting, one man cuts off or breaks off the fruits (depending on the cultivar) and tosses them to a truck or passes them to 2 other workers with baskets who convey them to boxes in which they are arranged with the stems upward for the removal of bracts and application of a 3% solution of benzoic acid on the cut stem of all fruits not intended for immediate processing. The harvested fruits must be protected from rain and dew. If moist, they must be dried before packing. All defective fruits are sorted out for use in processing. If the work is semi-mechanized, the harvesters decrown and trim the fruits and place them on a 30-ft conveyor boom which extends across the rows and carries the fruits to a bin on a forklift which loads it onto a truck or trailer. Some conveyors take the fruits directly into the canning factory from the field. In most regions of the world, pineapples are commonly marketed with crowns intact, but there is a growing practice of removing the crowns for planting. For the fresh fruit market, a short section of stem is customarily left on to protect the base of the fruit from bruising during shipment. Total mechanical harvesting is achieved by 2 hydraulically operated conveyors with fingers on the top conveyor to snap off the fruit, the lower conveyor carrying it away to the decrowners. After the fruit has been conveyed away, the workers go through the field to collect the crowns (where they have been left on the tops of the plants) and place them on the conveyors for a trip to the bins which are then fork lifted and the crowns dumped into a planting machine. Life of plantation In Florida, 'Abakka' fields were maintained for 2, 3, or 4 crops. Some plantings of 'Red Spanish' were prolonged for 25-26 years. In current practice, after the harvesting of the first crop, workers trim off all but 2 ratoons which will bear fruit in 15-18 months. Perhaps there may be a second or third ratoon crop. Then the field is cleared to minimize carryover of pests and diseases. The method will vary with the interest in or practicality of making use of by products. In Malaya, fields have been cleared by cutting the plants, leaving them to dry for 12-16 weeks, then piling and burning. Spraying with kerosene or diesel fuel makes burning possible in 9 weeks. Spraying with Paraquat allows burning in 3 weeks but does not destroy the stumps which take 3-5 months to completely decay while new plants are set out between them. Field practices will differ if pineapples are interplanted with other crops. In Malaya, pineapples have been extensively grown in young rubber plantations. In India and Sri Lanka the pineapple is often a catchcrop among coconuts. Venezuelan farmers may interplant with citrus trees or avocados. Storage Cold storage at a temperature of 40°F (4.44°C) and lower causes chilling injury and breakdown in pineapples. At 44.6-46.4°F (7-8°C) and above, 80-90% relative humidity and adequate air circulation, normal ripening progresses during and after storage. At best, pineapples may be stored for no more than 4-6 weeks. There is a possibility that storage life might be prolonged by dipping the fruits in a wax emulsion containing a suitable fungicide. Irradiation extends the shelf life of half- ripe pineapples by about one week. Sources: http://www.hort.purdue.edu/newcrop/morton/pineapple.html
