Thinning
Thinning should be done within 15 to 20 days after sowing by keeping only one healthy plant per hill by keeping one plant 20 centimeters apart in rows.

Earthing up
Five weeks after sowing, when the plants attain knee-high stage, earthing up should be done with the help of local plough or hoe. This provide safe guard against lodging which is likely to occur at cob formation stage due to high wind velocity and also helps to drain out water during rainy season as maize crop can not withstand stagnation of water.

Watching
The crop requires protection against Parrots, Crows and human beings when crop comes in tasseling and cob formation stage as they attack tassels and green cobs. Watching should be continued till crop is harvested. Shooting away the birds from manchas prepared in the field and beating drums are effective methods. Most of the new high yielding hybrids have thick covers and birds cannot do much damage.
