Abstract
In this study the runoff collected from catchment area , is utilized directly to irrigated wheat crop to meet its the water requirements with design the micro catchment water harvesting system (ratio catchment C area to crop area CA) based on the climate , crop and soil data. The design rainfall was estimated at 80% probability and crop water requirement by Penman-Monteith. The experiment was divided to three ratioC:CA 3:1 , 8:1 and 10:1 on the area of 25m² , dikes are used on the cropped area with 15 cm height to collect the maximal runoff from the catchment area and use water content in soil profile for increasing yield. The results showed that the grain yield increases from 1260 kg/ha to 1700 kg/ha with the increase in the size of catchment area , and that the water content in crop area and the collected runoff and its percentage of materiel suspended increase with the increase in depth of rain dropping on catchment area.
