• It needs 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.

Fertilizer Management:

• 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.

Critical Stages:

• Just after germination
• Knee height stage
• Pollination stage
• Grain development stages

Note:

• 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.
