Abstract

The research was carried out in Southern parts of Karnataka to determine the hydraulic parameters such as coefficient of manufacturer variation, emission uniformity; uniformity coefficient, application efficiency, and distribution efficiency for all irrigation systems of different makes were found to be excellent at both 0.75 and 1.00 kg/cm2 operating pressure for all irrigation systems of different makes. The distribution of water application and discharges from emitters along the lateral was measured using ASAE criteria. On a sub main, one at the inlet, one at the far end, and two in the middle at the one-third and two-thirds positions will be selected. On each lateral, the four dripper sites are tested: one at the input, one at the submain, and one at the outlet. As a result, there are a total of 16 measurement points. This is accomplished by measuring the flow volume collected in a graduated cylinder over a ten-minute period, and repeating the procedure for different pressure range
