In: Misr Journal of Agricultural Engineering 2013.v.30(1)Summary: The water-use characteristics of wheat were studied in the field under sprinkler irrigation system. Treatments consisted of two sprinkler irrigation systems, solid set sprinklers (S1) and hand move laterals (S1), arid three irrigation frequencies (IF1: once per week; IF2: twice per week, IF3: three times per week). Total irrigation amount values varied from 4558.160 to 5094.992 m3.ha"1 in 2009-2010 and 4792.457 to 5471.243 m3.ha-1 in 2010-2011. The highest seasonal ET was obtained from the S2IF3 treatment in 2010-2011 (5417.073 m3.ha-1); the lowest value was observed in the S1IF1 treatment in 2009-2010 (4513.029 m3.ha-1). On average, the S1IF3 treatment gave the highest grain yield (6000 kg.ha-1), whereas S2IF1 treatment gave the lowest grain yield (3332.500 kg.ha-1). The highest irrigation water use efficiency (IWUE) values were obtained from S1IF3 1.179 kg.m-3 and 1.151 kg.m-3 in 2009-2010 and 2010-2011, respectively, while the lowest values were obtain~d from S2IF1 0.710 kg.m-3 and 0.699 kg.m-3 in 2009-2010 and 20l0-2011, respectively. The highest water use efficiency (WUE) values were obtained from S1IF3 1.191 kg.m-3 and 1.163 kg.m-3 in 2009-2010 and 2010-2011, respectively, while the lowest values were obtained from S2IF1 0.717 kg.m-3 and 0.706 kg.m"3 in 2009-2010 and 2010-2011, respectively. The highest nitrogen use efficiency (NUE), phosphor use efficiency (PUE) and potassium use efficiency (KUE) were obtained under S1IF3 and the lowest value was obtained under S2IF1. Soil water content varied apparently in the 0-40-cm soil layer. For winter wheat in the El-Nubaria, the recommended sprinkler system and irrigation frequency for each event is solid set sprinkler (S J) and irrigation three times per week (IF 3). Key words: Irrigation frequency, solid set sprinkler, hand move laterals, wheat, IWUE, WUE, soil moisture content.
