Farming Advisories
N AREAS AFFECTED BY ITCZ, EASTERLIES AND MODERATE TO HEAVY RAINS Be alert and extra careful to those living in low lying areas and near mountain slopes due to possible flooding and landslides; inspect farm houses, barns and light-built structures and make repairs; Clean creeks, canals and ditches; store harvested crops in elevated, well ventilated and covered places. Water impounding is advisable during heavy rains for future use. LA NIÑA ADVISORY Continuous wet weather condition brought by La Niña, promotes fungal development and can cause damage to stored farm products, reduce the quality, viability and market price of the grains. Thus, it is advised to keep barns and crop storage rooms to be in good, dry, well ventilated condition. FOR WET (IRRIGATED) AND MOIST AREAS Land and seedbed preparation; planting and transplanting; removal of weeds and cultivation, harvesting of matured crops, use covered vans in delivery of goods in the market; planting of fruit trees to replace the old ones. FOR DRY (RAINFED) AREAS WITH LIGHT TO MODERATE WINDS Watering crops during early morning and evening periods will help alleviate stress on crops. Animal housing must be well ventilated; cogon and nipa as roof materials are advisable. Sun drying of newly harvested rice and corn; watering activities or irrigation using pump in rainfed areas.
Fishing Advisories

Slight to moderate seas will be experience over the whole archipelago. Be reminded to be very careful in going out fishing specially those using small sea craft. Always bring emergency kit. Be updated for the latest weather update and farm advisories

Red Tide Alert
(Courtesy of BFAR, Shellfish Bulletin No. 13, Issued on 01 May 2021)

All types of shellfish and acetes sp. or alamang gathered at coastal waters of Dauis and Tagbilaran City in Bohol; Tambobo Bay, Siaton in Negros Oriental; coastal waters of Calubian in Leyte; Balite Bay, Mati City in Davao Oriental; Lianga Bay and coastal waters of Hinatuan in Surigao del Sur; and Puerto Princesa Bay, Puerto Princesa City in Palawan are still positive for paralytic shellfish poison and not safe for human consumption. Fishermen are advised not to gather, not to sell, not to buy, and not to eat all types of shellfish and acetes sp. or alamang over these areas. Fish, squids, shrimps, and crabs are safe for human consumption provided that They are fresh and washed thoroughly, and internal organs such as gills and intestines are removed before cooking.

10 - Day Regional Agri-Weather Information

DEKAD NO. 13      01 – 10 MAY 2021

Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the low pressure area (LPA), inter-tropical convergence zone(ITCZ), easterlies, and localized thunderstorms.

Partly cloudy to cloudy skies with isolated rainshowers and thunderstorms will likely prevail over the whole archipelago. During the last part of the dekad, cloudy skies with scattered rainshowers and thunderstorms will likely experienced over southern portion of Mindanao.

Easterly to northeasterly winds will blow over the whole archipelago.

Slight to moderate seas will likely prevail over the whole archipelago throughout the forecast period.

La Niña continues to weaken. A transition to ENSO-neutral condition will be likely in May-June-July 2021 season.
Farm Advisories

Please observe the Memorandum Order on Stringent Social Distancing Measures and Further Guidelines for the Management of Corona Virus Disease 2019 (COVID-19)

Rice is best stored as paddy because the husk provides some protection against insects and helps prevent grain quality deterioration. A safe storage system will prevent the grain from getting wet after drying and also give protection from insects, rodents, and birds.

Rice can be stored for longer periods if:
• Moisture content is maintained at less than 14% for grain and 12% for seed;
• Grain is protected from insects, rodents, and birds; and
• Grain is protected from re-wetting by rain or from the surrounding air.

A rule of thumb for seed is that the life of the seed will be halved for every 1% increase in moisture content or a 5°C increase in storage temperature above recommended levels.

For additional knowledge to attain potential crop production, farmers are encouraged to join government projects. These will enable them to learn and experience science-based crops and cropping system technologies and gain from such projects’ activities as sample advisories like planting dates, early warning for pest and disease infestation, water management strategies for specific areas, and daily weather condition notifications are also available (e.g., ACIAR, SARAI projects, etc.).
