Itneeds 450 to 600 mm of water per season, which is mainly acquired from the soil moisture reserves.
About 15,0 kg of grain are produced for each millimeter of water consumed. At maturity, each plant will have consumed 250 lt of water.
It is advisable to follow N: P: K application at the rate of 48:24:20 per acre for best yields.
All P & K and 1/3 of N should be applied as basal dose at the time of sowing.
Balance Nitrogen can be applied in two split doses — first dose between 35-40 days and the second dose at the time of tassels emergence.
Basal application of Zinc Sulphate at 10 kg/acre is also recommended.
Application of organic manure/rotten compost/FYM at the rate of 8mt/acre is most ideal for increased yield.

Grain development stages
It is very essential to maintain moist conditions during pollination to grain filling stage for better disease tolerance and corn yield.
Healthy crop can resist and delay the disease occurrence. In case if the soils are heavy, irrigation should be light & frequent. However adjust the number of irrigations based on environmental conditions.
