Abstract	Two field experiments were carried out at the Agricultural Production and Research Station, National Research Centre (NRC), El Nubaria Province, Egypt, during the two successive winter seasons 2010/2011 and 2011/2012. The aim of this study was to investigate the effects of fertigation levels and irrigation requirements (IR) on growth, yield and water use efficiency in wheat (Sakha 93 cv). The results showed that decreasing of fertigation levels from 100% to 50% NPK of the recommended fertilizer doses significantly decreased most studied growth characters, yield and yield attributes, protein and carbohydrate contents while, water use efficiency increased. Decreasing the IR from 100% to 50% significantly decreased most of growth characters, yield and yield attributes, protein while, water use efficiency significantly increased. However, decreasing the IR from 100% to 50% decreased grain, straw and biological yield/faddan (one faddan=0.42 ha), from 1.91 to 1.27, from 4.66 to 3.48 and from 6.57 to 4.75 ton/faddan, respectively. The treatment 100% NPK of the recommended fertilizer + 100% IR records the highest values of the studied growth characters, spike length, seed index and biological yield/faddan while, 75% NPK recommended fertilizers + 100% IR surpassed in number of spikelets/spike, number of spikes /m , grain and biological yield/ faddan. 2
