Before carrying out the field operations, green manure crops like dhaincha (50 kg seeds/ha) or sannhemp (100 kg seeds/ha) should be sown in last week of May and it should be buried into the soil 35-40 days after sowing before flowering with disc harrow or tractor drawn plough. For rapid decomposition of green manure crop, full dose of phosphatic fertilizers should be applied in the soil and about 4-5 cm of water should be given in the field which helps in easy decomposition of green manure as well as weed plants and stubbles of previous crop. Before transplanting, the field should be puddled by three to four runs of puddler in 4-5 cm standing water followed by planking for levelling.

Advantages of puddling
1) Drainage can be reduced as the sub soil layer may become impermeable.
2) Seedlings can set easily in soil.
3) Weeds can be destroyed.
4) Manures and fertilizers can be well mixed in the soil.
