1/1

Land preparation is the process of preparing the rice field to provide a

soil condition favorable for plant growth. This facilitates water,

nutrient, and pest management.

Dry land tillage

In May to June and November to December, plow and harrow the

field once immediately after harvest or when the soil has dried using a

4-wheel tractor mounted with a rotary or multiple trailing disc plow or

harrow. This is to aerate the soil, reduce weeds and other pests, and

incorporate crop residues into the soil.

Wet land tillage

When water is released by NIA in June and December, flood the field

for one to two days. At 21 days before transplanting (DBT) or direct

wet-seeding (DBS), plow the field once using a hand tractor or

rotavate with 20-40 hp four-wheel tractor.

A week after plowing, harrow the field. Repeat harrowing one week

after using a handtractor. Do the final harrowing and leveling one or

two DBT/DBS using a tractor-drawn wooden plank.
