Performance Evaluation of Drip Irrigation Systems

The field experiments were conducted to evaluate the performance of drip irrigation systems at protected cultivation unit of College of Horticulture and Forestry, Jhalawar, Rajasthan during 2013-14 and 2014-15. The performance of drip system was evaluated on the basis of parameters like average discharge (Qavg), field emission uniformity (EUf), design emission uniformity (EUd¬), application efficiency (EUa and Ea), coefficient of variance (Cv) and statistical uniformity coefficient (SUC). The distribution efficiency values of 93.63, 93.46 per cent for NVPH and 95.70, 95.38per cent for ECPH environment and SUC values of 92.38, 91.97 per cent for NVPH and 94.46, 94.28 per cent for ECPH during both the year respectively were estimated. As per the ASAE Standards, the Cv is classified as good performance for entire experiment during both the years since calculated Cv is less than 0.10. The designed drip irrigation system was operated excellently as the values of EU were nearly equal or more than to design criteria of 90 per cent in each case.
