Rice can be directly seeded either through dry or wet (pregerminated) seeding.
Dry seeding of rice can be done by drilling the seed into a fine seedbed at a depth of 2-3 centimeters.
Wet seeding requires leveled fields to be harrowed and then flooded (puddling). The field is left for 12-24 hours after puddling, then germinated seeds (48-72 hours) are sown using a drum seeder.
Seed can be broadcast for either dry or wet seeding, but manual weeding is more difficult. Indeed, weed management is a critical factor in direct seeding.
Timely application of herbicides (timing is dependent on the method of seeding) and one or two hand weedings provide effective control.
