Barley a members of the Poaceae family is an important grain crop globally. It occupies fourth place in importance after wheat, maize and rice and locally. It is one of the , is one of the important grain crops planted by humans for food thousands of years ago,(The study aimed at estimating crop production costs and expected returns, estimating the productivity and economic efficiency of the water unit, this point will used to irrigate a Feddan of the barley crop by following the new irrigation systems and determining the spray irrigation system, identifying the economic and social characteristics of the farmers in an easy area, that estimation of the economic revenue of the water unit used in irrigating of barley crop Feddan. When using the new irrigation systems (sprinkler irrigation), the farmer achieves a saving in the productivity of the Faddan and the quantity of irrigation water from the barley crop by 16.7% and 25%, respectively, of the average productivity of the Faddan and the user of the irrigation water per Faddan of the barley crop in the case of surface irrigation And the adult at a significant level 0.01 barley yield in the study area, the value of (f) 135.75.195.67.49.76,227.61,160.04, respectively.
