The purpose of this evapuation is to determine the existing efficiencies of the system and finally identify the current situation and thus provide solutions and scientific and practical suggestions to increase the efficiency has been performed based on the guideline of Soil Conservation Service and Measurements in any field were included pressure and discharge of emitters to calculate the parameters of Emission Uniformity, Statistical Efficiency of Low Quarter, check the status of the central control and talk to farmers about the state of the system strategy. The average amounts of the measured indices in A11, B2, D4, C7 and E5 systems were respectively: Emission uniformity 76.31, 61.33, 83.55, 63.85 and 43.62%, Statistical uniformity coefficient 88, 64.03, 91, 63 and 69%, Efficiency reduction factor 0.9, 0.69, 0.96, 0.95 and 0.85, Potential application efficiency of low quarter 62.01, 38.08, 72.18, 54.59 and 33.37% and Application efficiency of low quarter 68.9, 42.31, 80.2, 60.65 and 37.07%. Examining the central control station in the fields, it was found that two systems had good central control station status and the other three systems did not have good condition. Due to the results obtained, the problems of strip drip irrigation systems in these areas included great weakness in the management of operation and maintenance of systems by farmers, inadequate pressure and its uneven distribution in the systems, not-adjustment of inlet valve on manifold, opening the end of latterals for surface irrigation, lack of cleaning filters and clogging of some emmiters
