Maize crop is sensitive to both moisture stress and excessive moisture, hence regulate irrigation according to the requirement. Ensure optimum moisture availability during the most critical phase (45 to 65 days after sowing); otherwise yield will be reduced by a considerable extent.

Regulate irrigation according to the following growth phase of the crop. Germination & establishment phase 1 to 14 days Vegetative phase 15 to 39 days Flowering phase 40 to 65 days Maturity phase 66 to 95 days
