Giralt P. E. Maize water requirement.
Research Institute of Irrigation and Drainage, 1984, Havana
Water requirements of maize for two seasons, in Ferrallitic soil at the Irrigation Experiment Station in Havana was determined. Maize sown in spring is harvested from 110 to 125 days, in winter sown the harvest delay from 125 to 140 days. The wet grain corn is harvested between 80 to 90 days in spring and from 85 to 95 days in winter. The dry grain corn requires 330 to 412 mm of water for growing, wet corn grain requires from 250 to 300 mm water.
Maize is a plant with relative tolerance to water deficit, the more critical water requirements are at the stage of seed-germination and the phase formation of the spike-grain milky which should guarantee an adequate water supply. To ensure uniformity of germination must irrigated with soil moisture of 90-95% of field capacity to a depth between 25 and 30 cm., at other stages were irrigated to a depth between 30 and 40 cm., making sure that soil moisture does not drop of 85-80 % of field capacity.
