- Irrigate immediately after sowing followed by life irrigation on 5th day after sowing.
- Subsequent irrigation to be done according to the climate and soil condition.
- Ensure irrigation on critical stages namely germination phase (1-15 days), vegetative phase (16-44 days) and flowering phase (85-90 days)
- Acalypha indica, Cyanodon dactylon, Cyperus rotundus, Digera arvensis, Chloris barbata, Trianthema portulacastrum and Parthenium hysterophorus are the major weed species
- Maintain the field weed free during critical stages viz., vegetative and flowering phases .
- Need based manual weeding and stubble mulching with organic materials to control weeds.
