Although wet direct-seeded rice (W-DSR) does not save much water compared to D-DSR, this practice is recommended when the late onset of monsoon rain does not allow farmers to sow the crop in time. Application of irrigation water and sprouted seeds can help to sow the crop through the direct seeding method on time and this method uses less water compared to the traditional transplanting.W-DSR involves sowing of pre-germinated seeds (radicle 1- 3 mm) on or into puddled soil through manual broadcasting or tractor-drawn drum seeder. When pre-germinated seeds are sown on the surface of puddled soil, the seed environment is mostly aerobic and this is known as aerobic W-DSR. When pre-germinated seeds are sown/drilled into puddled soil, the seed environment is mostly anaerobic and this is called anaerobic W-DSR.  The W-DSR under aerobic and anaerobic, seeds can either be broadcasted or sown in-line using a drum seeder or an anaerobic seeder with a furrow opener and closer. The yield in W-DSR rice crop is at par with that of transplanted rice when proper management practices are followed. It also increased water productivity by 0.3 to 0.4 kg rice m-3 water.
