A field experiment was conducted in two successive seasons to study the effect of drip (DI), low head bubbler (LHBI) and gated pipe (GPI) irrigation systems on yield, water consumption (WC), water use efficiency (WUE) and fertilizer use efficiency (FUE) of grape (Thompson seedless) crop grown in clay loam soil in El-Kanater El-Kheiria district, Qalubia Governorate, Egypt. Yield of the 1st season was lower than that of the 2nd one. Minimum and maximum yield values were 2166; 3776, 1982; 2888 and 2059; 3506 kg/fed under DI, GPI and LHBI systems, in the 1st and 2nd season, respectively. Grape yields under DI and LHBI systems were about 9.3; 30.7% and 3.9; 21.4% higher relative to that under GPI one in the 1st and 2nd season, respectively. According to WC, irrigation systems could be arranged in the following ascending order in both seasons GPI < LHBI < DI. Water consumption increased by 89; 86% and 86; 65% under DI and LHBI systems relative to GPI one in the 1st and 2nd season, respectively. Concerning the mean values of WUE in the 1st and 2nd season, they were 1.49 and 1.97 kg/m3 irrigation water, respectively. Values of WUE under DI and LHBI systems exceeded that under GPI one by 139; 121% and 133; 112% in the 1st and 2nd season, respectively. With respect to FUE values, they were higher in the 2nd season than in the 1st one. For the N, P2O5 and K2O, their FUE under DI and LHBI systems overpassed that under GPI one by approximately 9; 4% and 31; 21% in the 1st and 2nd season, respectively.
