Abstract

Limited water resources and the climatic conditions of Iran are the main problem in increasing agricultural production. DRIP IRRIGATION methods are an ideal solution for the optimal use of water resources due to their high POTENTIAL EFFICIENCY of water distribution. In the present study, the condition and performance of the 8 DRIP IRRIGATION systems implemented in Sarbaz region were evaluated and parameter uniformity coefficient (CU), DISTRIBUTION UNIFORMITY (DU), application POTENTIAL EFFICIENCY of low quarter (PELQ) and application efficiency of low quarter (AELQ), Emission uniformity (EU) and the maximum pressure difference (DP max) calculated in trickle irrigation system were 93.31, 89.51, 68.66, 72.6, 76.5 and 42.85 percent, respectively. In order to better analyze dripper discharge, the variation curve in the lateral pipes on manifold has drawn. In system AW1, there has been excessive irrigation needs. And there was a deepwater loss in the system. While in the rest of the system, the water requirements are far less than the amount of irrigation and deficit irrigation was done unintentionally.In general, it can be said that the key problems of trickle irrigation systems in Sarbaz region are due to the lack of care in design, implementation, management and maintenance of systems, inefficiency of pressure and its inconsistent distribution and lack of wetted area because inefficient trickle layout.
