Farming Advisories
FOR AREAS AFFECTED BY ASHFALL DUE TO VOLCANIC ACTIVITY: STAY INDOORS, ALWAYS WEAR MASK, CLOSE ALL WINDOWS AND DOORS INCLUSING BARNS. KEEP ANIMALS IN A SAFE, CLOSE STRUCTURE. IF ABLE, ENSURE THAT ALL PRODUCE ARE KEPT IN A CLOSE TIGHT DRY PLACE. EVACUATE IF NECESSARY.
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; CLEAN CREEKS, CANALS AND DITCHES FROM IMPEDIMENTS TO PROVIDE NATURAL FLOW OF WATER SPECIALLY DURING THUNDERSTORMS TO AVOID POSSIBLE FLOODING ; PLANTING OF FRUIT TREES TO REPLACE THE OLD ONES.
FOR (RAINFED) DRY AREAS WITH LIGHT TO MODERATE WINDS: SUN DRYING OF NEWLY HARVESTED RICE AND CORN; WATERING ACTIVITIES OR IRRIGATION USING PUMP; FUNGAL DEVELOPMENT CAN CAUSE DAMAGE TO STORED FARM PRODUCTS, THUS, IT IS ADVISED TO KEEP BARNS AND CROP STORAGE ROOMS TO BE CLEAN,DRY, WELL VENTILATED AND IN SAFE CONDITION; DELIVERY OF GOODS IN COVERED VANS CAN BE DONE. BE VIGILANT AND ALWAYS INSPECT YOUR RICE FIELDS FOR OCCURRENCE OF PESTS AND DISEASES, ASK FOR PRECAUTIONARY MEASURES OR CONSULT THE EXPERTISE OF YOUR LOCAL AGRICULTURIST.

10 - Day Regional Agri-Weather Information

DEKAD NO. 02      JANUARY 11 – 20, 2020

Philippine Agri-Weather Forecast
The weather systems that will likely to affect the whole country are the northeast monsoon, tail-end of a cold front, easterlies and low pressure area.

During the early days of the dekad, cloudy skies with light rains will be experienced over Cordillera, Cagayan Valley, Aurora and Quezon while Metro Manila and the rest of Luzon will experience partly to cloudy skies with isolated light rains brought by northeast monsoon. Likewise, a Low Pressure Area will bring cloudy skies with scattered rainshowers and thunderstorms over Quezon, Bicol Region, Eastern Visayas, and CARAGA. As the LPA dissipates, the tail-end of a cold front will continue to bring cloudy skies with scattered rainshowers and thunderstorms over Cagayan Valley, Aurora, Quezon and Bicol Region. During the last part of the dekad, cloudy skies with scattered rainshowers and thunderstorms will persist over Cagayan Valley, Aurora, and Quezon while the rest of the country will have better weather condition except for isolated light rains over the rest of Luzon and isolated rainshowers and thunderstorms over Visayas and Mindanao.

Northeasterly windflow will prevail over the country except for northeast to northwest winds over the eastern side of Visayas and Mindano as the LPA moves closer to Bicol Region- Eastern Visayas Area. Easterly to northeasterly winds will continue to blow over the whole country for the rest of the forecast period.

The eastern seaboards of the whole country will likely to have moderate to rough sea condition while the rest of the country will have slight to moderate seas.


ENSO-neutral condition still persists and will likely to continue throughout the forecast period.
Farm Advisories

Farmers are reminded that the most suitable rice variety is the one that best meet the farmer and consumer’s need. It may not always give the highest yield and will be influenced by availability of water (either from rain or irrigation), soil type, and field elevation, and whether the rice will be sold or consumed at home. Varieties should be selected based on good yield potential, resistance to disease, good eating qualities, high milling yield, and are suitable for the market.

During transplanting stage, water is critical during the first 10-days after transplanting, as this is the time weed seeds also begin to germinate. Maintaining enough water will suppress the weed growth.

Moreover, during the vegetative stage, when applying a fertilizer, reduce water level to field saturation point, just enough to dissolve the fertilizer. Do not, however, dry the field.
