How seed treatment is done in SRI method of rice cultivation?

Healthy and pure seeds are used for seed treatment. Soak the seeds for about 12 hours in water, then drain the water and treat the seeds by using Bavistin (2gm/kg seed) or Trichoderma (3 gm/kg seed). There after transfer the treated seeds to a water-soaked gunny bag and leave it for 24 hours. Then, sprouted seeds are taken to the nursery for sowing seed. Divide the seed into 4 parts and broadcast thinly over the bed or each part at a time to ensure uniform broadcasting. Also, it is better to broadcast seeds in the evening.
