  • Sowing of sprouted seeds on the raised nursery; protect the seeds from rain

3-5

  • Weed management (if needed). Care is taken so that seedbed won’t dry up nor should give excess water.

10-20

  • Pest / disease management practices and top dressing with 0.3 to 0.6 kg of N for every 100 sq.m.
