| The current study was carried out at Agricultural and Veterinary Research Station, Faculty of Agriculture and Veterinary Medicine, Qassim University, Kingdom of Saudia Arabia during 2007/08 wheat growing season. The objective of this study is to investigate the effect of sprinkler irrigation uniformity on sprinkler irrigation uniformity coefficient on water losses by deep percolation, wheat crop yield and height, water use efficiency, uniformity coefficient of crop yield and height through field experiments. The other purpose is to obtain the response of wheat crop height yield to seasonal applied water. Treatments consisted of five sprinkler irrigation uniformity: "CUc1" (>90- <95%), "CUc2" (>80- <85%),"CUc3" (>70- <75%), "CUc4" (>60- <65%) and "CUc5" (>50- <55%). The results indicated that sprinkler irrigation uniformity coefficient affected all parameters of this study. By increasing sprinkler irrigation uniformity wheat crop yield, plant height, adequacy of irrigation and water use efficiency were increased while water losses by deep percolation and irrigation insufficient were decreased. High irrigation uniformity enhanced wheat growth, water use efficiency and worse water losses by deep percolation. Uniformity coefficient values for crop height, grain yield and water use efficiency of wheat were higher than the values of sprinkler irrigation Uniformity coefficient. | ||
