Field experiments were conducted in Al-Hassa, Saudi Arabia, during the 2002/03 and 2003/04 winter seasons, to determine the effect of different irrigation regimes on wheat productivity and water use efficiency (WUE) under subtropical arid conditions. The treatments comprised: irrigation every 5 days at 500 m3/ha (13950 m3/ha/season); irrigation every 10 days at 650 m3/ha (9750 m3/ha/season); irrigation every 15 days at 800 m3/ha (8350 m3/ha/season); and irrigation every 20 days at 950 m3/ha (7650 m3/ha/season). Results showed that the different irrigation regimes significantly affected the grain, straw and biological yields/ha. The grain, straw and biological yields were significantly increased as the volume of irrigation water increased. The 9750 m3/ha irrigation regime recorded the highest WUE for grain, straw and biological yields.
