Abstract
1 Increasing of water consumptive use efficiency and yield with influences of water stress and Potassium fertilization. 2 Field experiments: El <U+2013> Karda Station <U+2013> Kafer El Sheikh Governorate <U+2013> Egypt. 3 Experimental design: A split plot design with three irrigation treatments at depletion of 25,50 and 75% from Available water with four Potassium fertilizer treatments and four replicates. 4 Water saving with irrigation treatments and Potassium fertilizer treatments. 5 Irrigation application efficiency. 6 Crop and field water use efficiency. 7 Crop coefficient K.C and the nearest value to potential evapotranspiration. 8 Statistical analysis for grain yield and straw. 9 Statistical analysis for Potassium content in grains and straw. 10 Economic evaluation: total return <U+2013> total cost ( Fixed and Variable), and water productivity.
