| Abstract | ||
| Two field experiments were conducted at Nubaria Agricultural Research Station in two successive seasons 2012-2013 and 2013-2014 to study the performance of wheat cultivars (V1=Misr1and V2= Sids12),four irrigation (I1= irrigation water equals 50% of crop evapotranspiration (ETc), I2 = irrigation water equals 75 % of (ETc) I3= irrigation water equals 100% of (ETc), and I4= irrigation water equals 125% of (ETc) and nitrogen source (N1= Ammonium nitrate and N2 = Ammonia gas )on wheat biological, grain yields, yield components, water requirements and productivity of water. Results showed that, biological and grain yields, plant height, number of spikes /m2, number of kernels / spike and1000 kernels weight were significant affected by the interaction irrigation, nitrogen source and cultivar in both seasons. The highest values of biological and grain yields were 24.333 and 7.500 ton.ha-1 in the first season respectively, while in the second season, values were 26.333 and 9.500 ton.ha-1,which obtained by irrigation with water equals to 100% of ETc, fertilization by gas ammonia with cultivarSids12 (I3 N2 V2). The total applied irrigation water for I3 irrigation were 37.0 and 40.1 cm in both seasons, respectively. The highest values of productivity of irrigation water (PIW) were 2.00 and 2.62kg.m3, in the first and second seasons, respectively. | ||
