Abstract

ABSTRACT CORN was irrigated using three (2.5 cm, 5.0 cm and 7.5 cm) net irrigation application depths to de-termine the effect of application depth on grain yield, water utilization efficiency and soil water movement. Grain yields and water utilization efficiencies were not affected by the application depths. The average rate of water removal from a 90 cm soil profile during July and August was 0.54 cm/day
