Summary
The seasonal consumptive use, Et per day and water use efficiency (kg grain/ha-cm) of corn were determined on a sandyloam soil during winter (rain-free) season. The difference in consumptive use was less among nitrogen levels, but marked between different moisture regimes. Et per day was less in the initial stages of the growing season, attained a peak at 80% of the crop growing season, and declined later on towards maturity. Water use efficiency was found to increase with increase in N level up to 180 kg N/ha. Among the moisture regimes, higher water use efficiency was recorded under 20% ASMD.
