Abstract
Two field experiments were conducted at Shandaweel Agricultural Research Station, during 2002/03 and 2003/04 seasons. Three irrigation regime treatments, i.e , 0.8, 1.0 and 1.2 evaporation pan coefficients with four bread wheat cultivars, Sakha 93, Giza 168, Gemmeiza 7 and Gemmeiza 9 to find out the specific pan-coefficient needed for scheduling irrigation of wheat using class A pan evaporaticn records under different wheat cultivars at Upper Egypt region. The results revealed significant differences among studied cultivars and irrigation treatments in all studied traits in the second season. The irrigation treatment at 1.2 evaporation pan coefficient gave the best results with Gammeiza 7 regarding to vegetative growth traits, grain yield and its components. The irrigation at 1.2 evaporation pan coefficient with Gammeiza7 cultivar produced the highest grain yield (26.66 and 26.10 Ardab/fed) for the first and second seasons, respectively. The irrigation treatment at 1.2 evaporation pan coefficient recoded the highest amount of water consumed more than the other two treatments. Water consumptive uses by wheat were 1582.4, 1796.9 and 2215.9 m³/fed, for irrigation treatments at 0.8, 1.0 and 1.2 evaporation pan coefficients, respectively. The irrigation at 0.8 evaporation pan coefficient gave the highest value of water use efficiency. From these results, it could be concluded that the application of irrigation water at 1.2 evaporation pan coefficient could be recommended with wheat cultivar Gammeiza7 for high production under Upper Egypt conditions.
