certified seeds or clean seed from a known source free from admixture of weed
seeds.

- Cleaning seeds by dipping in
2% brine solution (salt solution) helps in the selection of high-density seeds
and separation of floating weed seeds.
- Off-season ploughing after
rice harvest reduces weed seed replenishment.
- Deep summer ploughing once
in three years
