Abstract:

A field study was undertaken to evaluate the performance of 4 lph capacity inline drip emitter in farmer’s field at 0.75 kg/cm2 and 1.00 kg/cm2 operating pressure. The efficient water application through drip irrigation is mainly depends upon the hydraulic parameters of the system, which includes the effect of pressure on coefficient of manufacturer variation, emitter flow variation, emission uniformity, uniformity coefficient, application efficiency and distribution efficiency. The results of the hydraulic parameters evaluation revealed that the coefficient of manufacturer variation, emission uniformity, uniformity coefficient, application efficiency and distribution efficiency were found to be excellent at both 0.75 and 1.00 kg/cm2 operating pressure for all the farmers’ fields. However, among the farmers field, emitter flow variation was observed to be in only for 33.33% farmers’ fields at 1.00 kg/cm2 operating pressure and it was not acceptable at 0.75 kg/cm2 for all the farmers’ fields.
