Abstract:

A field experiment was conducted in El-Bustan, Beheira, Egypt, in 1998, 1999, and 2000 to study the effects of irrigation method (drip and sprinkler irrigation), rate (50, 75, and 100% water consumptive use or WCU), and interval (irrigation daily and irrigation at three-day intervals) on maize (Single Cross 10) water use efficiency and yield. Higher grain yields were obtained with drip irrigation than with sprinkler irrigation. Irrigation at 100% WCU resulted in higher yields than irrigation at 50 or 75% WCU. Irrigation daily gave higher yields than irrigation at three-day intervals. The cost of maize production unit was lowest under drip irrigation system with 100% WCU applied daily, but highest under sprinkler irrigation system with 50% WCU applied at three-day intervals. Drip irrigation conducted daily resulted in the highest water use efficiency in maize. The actual seasonal irrigation water requirements by maize were lower than the calculated irrigation requirements under sprinkler and drip irrigation systems (by 13.7 and 22.6%, respectively).
