Farm Advisories

Farmers are advised to prepare land thoroughly to obtain successful rice production. It is reminded to prepare land 3 weeks before transplanting; fix all dikes, soak the field for 1 day to soften the soil, then plow to a depth of at least 10 cm to incorporate all weeds and rice stubbles for proper decomposition.

Flood the field after plowing to prevent nitrogen loss from the soil and to hasten decomposition of rice stubbles. Puddle the soil by harrowing 3-5 days after plowing and then begin second harrowing after 5-7 days. Keep the field flooded. Harrowing and final leveling should be finished a day before the scheduled transplanting.
