Two field experiments were performed in EL-Husain farm, Giza governorate under the condition of sandy soil during 2009/2010 and 2010/2011 seasons, to study the impact of three amount of water irrigation 60, 70 and 90% from evapotranspiration rate (1461 m 3) and three compost rates 2, 4 and 6 ton/fad. on some growth, yield and its components of two wheat varieties (Sakha 93 and Gemmeiza 9). Results of the two seasons showed that ,by increasing the water irrigation amount from 60 to 70 or 90 % of the evapotranspiration (1461 m 3) led to gradually significant increases for leaf area/plant , dry weight /plant, No. of spikes/ m 2 ,weight of grains /spike , No. of grains/spike , weight of 1000 grains, grain yield /fad. and harvest index .Compost rates had significant impacts on previous characteristics, during the two experimental seasons. The best compost rate was (6 ton/fad) which gave the best results for these traits as compared with the lowest rate (2 ton/fad). Results revealed that, Gemmeiza 9 wheat variety exceeded Sakha 93 wheat variety significantly for above mentioned measurements during the two seasons. As for the first and second order interactions between the tested factors, results in the two trial seasons revealed that, most of the interactions had significant effects on that character. It wealthy mentions that significant interaction effect was found between the three factors under testing during the two seasons. The highest values for previous characters were obtained by sowing Gemmeiza9 with adding irrigation quantity of 90% from evapotranspiration and practicing 6 ton compost per fad.
