Farming Advisories
LA NIÑA ADVISORY
Prolonged rainfall during La Niña, can proliferate destructive grain-sucking rice-bugs (liptocorisa) which can be abundant and can attack any time, be vigilant and always inspect your rice fields and ask local agriculturist for advice if there are any. 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. During La Niña, choose flood resistant rice varieties which are suitable in your farm or ask the advice and expertise of your local agriculturist.
IN AREAS AFFECTED BY LPA, NORTHEAST MONSOON, TAIL-END OF FRONTAL SYSTEM, AND AREAS WITH MODERATE AND WIDESPREAD RAINS AND THUNDERSTORMS

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. Construction of fishponds is favorable during the rainy days.
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.
Fishing Advisories

Moderate to rough sea conditions will be experienced over northern Luzon. Elsewhere, will have slight to moderate seas. 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.

DEKAD NO. 03      21 - 31 JANUARY 2021

Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the northeast monsoon (NE), tail-end of frontal system, low pressure areas (LPAs), easterlies, intertropical convergence zone (ITCZ) and localized thunderstorms.

During the early days of the dekad, cloudy skies with scattered rainshowers and thunderstorms will be experienced over Metro Manila, Cagayan Valley, Cordillera Administrative Region, Central Luzon, CALABARZON, MIMAROPA, central and western Visayas and Mindanao while the rest of the country will have partly cloudy to cloudy skies with isolated rainshowers. Cloudiness with scattered rainshowers will continue to prevail over Cagayan Valley and will likely affect Ilocos Region. The rest of the country will have fair weather conditions with isolated rainshowers. At the latter part of the forecast period, the eastern section of Luzon, Visayas and Mindanao will experience cloudy skies with scattered rainshowers and thunderstorms while the rest of the country will have partly cloudy to cloudy skies with isolated rainshowers.

During the early days of the dekad, winds coming from southeast to northeast will blow over Luzon while Visayas and Mindanao will have winds coming from east to southeast. Northeasterly winds will then prevail over northern Luzon while easterly to northeasterly winds will blow over the rest of the country. This wind condition will likely to continue to affect the country throughout the forecast period.

During the early days of the dekad, moderate to rough sea conditions are expected over the seaboards of Luzon while slight to moderate seas will be experienced over Visayas and Mindanao. At the mid of the dekad, moderate to rough sea conditions will also be experienced over the eastern section of Visayas and Mindanao. the rest of the archipelago will have slight to moderate seas. At the last days of the dekad, rough to very rough sea conditions will likely affect the eastern section of the country while moderate to rough seas will prevail over the western section of Luzon. Slight to moderate seas will be experienced over the rest of the country.

La Niña is likely to continue across the tropical Pacific through January-February-March 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) Situation)


Nutrient management before transplanting is important in obtaining potential crop production, farmers are reminded, to do the following:

One or two days before transplanting, drain water up to field saturation point and apply basal organic and inorganic N fertilizers before final leveling using the recommended rate per hectare:
Wet Season
- 6 bags 14-14-14
- 8 bags organic
Dry Season
- 6 bags 14-14-14 (may be increased to 8 bags)
- 8 bags organic(homemade compost or animal manure)
- 1 bag 45-0-0
Mix the basal fertilizer thoroughly into the soil.

For zinc-deficient soils, dip seedlings in 2% zinc oxide solution (2g/100 ml water) before transplanting or broadcast 10-20 kg/ha zinc sulfate into the flooded field after the first irrigation.
This is a general fertilizer rate recommendation. In less fertile soils, add 2 bags of 14-14-14 complete fertilizer during the dry season. Determine required NPK through soil analysis or follow local recommendations if there are any.
Use homemade organic fertilizers, such as crop residues and animal manure. A 5-ton palay harvest produces 5 tons or more of rice straws and stubbles, which can be incorporated into the soil three weeks before transplanting for proper decomposition.
Mixing the fertilizer with the soil is important to prevent nitrogen from evaporating, ant to put the fertilizer near the roots of the plants.
It is important to level the field properly to attain uniform water depth in the field. This helps suppress growth of weeds, and maximizes fertilizer availability in the field.
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.).
