Abstract: Field experiment was carried out at Dar El-Ramad farm, Faculty ofAgriculture, Fayoum University, Egypt during 2015/2016 and 2016/2017seasons. The trials aiming at investigating the effects of ridge width asplanting in wide ridges 120 cm (beds), 60 cm ridges and flat planting(basins) and irrigation scheduling regimes, based on 1.0, 0.8 and 0.6coefficients of Cumulative Pan Evaporation (C.P.E.) records on yield, yieldcomponents and some crop - water relations of wheat variety, Giza 168. Asplit plot design with four replications was used in both seasons. Theobtained results showed that planting in 120 cm ridges (beds) and irrigationat 1.0 C.P.E., gave the highest averages of spike number m-2, grains spike-1,1000-grain weight, straw yield (7411 and 7289 kg ha-1), and grain yield(6761 and 6581 kg ha-1) in the two successive seasons, respectively. Thelowest averages of yield and its components were obtained from flatplanting (basins) and irrigation at 0.6 C.P.E., in both seasons. Seasonalconsumptive use (ETC) averages were 42.48 and 41.14 cm in 1st and 2ndseasons, respectively. The highest ETC values were recorded with theinteraction (R3I1), whereas, the lowest values resulted from the interaction(R1I3). Daily ETC rates were low during November and December, thenincreased during January and February, to reach its maximum values duringMarch and then declined again till harvesting at April. The crop coefficient(KC) values (averages of the two seasons) were 0.47, 0.55, 0.65, 0.73, 0.93and 0.51 for, Nov., Dec., Jan., Feb., Mar. and Apr., respectively. Thehighest water use efficiency, i.e., 1.61 and 1.62 kg grains m-3 waterconsumed were obtained from (R1I1) treatments in first and second seasons,respectively.
