Abstract
Field experiment was conducted at EI-Serw Agricultural Research Station (North of Delta, Egypt) during the 2004 and 2005 summer season. The study is concerned with the effect of water table levels (40 to 50 cm and 70 to 80 ern), irrigation water depths (4.5, 9 and 12 cm) and nitrogen fertilizer levels 30,60 and 90 k N fed:') on rice yield, yield components, amount of applied water, actual evapotranspiration (ETa), seepage, percolation losses, and water use efficiency. The early maturing rice cultivar Giza 178 was used in this experiment. A split-split- plot design with four replicates was used. The results indicated that the highest value of water use efficiency (WUE) is 0.76 kg grainl m3 for deep water table (70-80 cm), irrigation water depth 9 cm with nitrogen fertilizer 60 kg fed. ".
