Abstract
The study evaluated the performance of drip irrigation system under different hydraulic
heads using drip giving set as emitter. A plot was equally divided into three sub-plots and
three lateral each with 2.4m length were laid on the ground. A plastic tank reservoir was
provided to each plot with metal stands which suspended the tank from the ground surface.
The height of the tank were varied from 0.5m, 1.0m, and 1.5m for plots A,B and C
respectively, so as to vary the hydraulic head as well as hydraulic pressure. The system
performance was tested for its water application rate, uniformity coefficient, manufacturing
coefficient of variationand discharge relationship. The study reveal that, the maximum
discharge rate of 0.410,0.210 and 0.200 lt/hr for plot A, b and C respectively were obtained
in the drip arrangement which falls within the acceptable range of 0.2 to20Ltrs/hr as
recommended for micro-irrigation system by many literatures.Coefficient of uniformity of
68, 74 and 99 percent for plot C, B and A respectively were obtained for the system also
falls within the acceptable range except manufacturing coefficient of variation which is
marginal to unacceptable range of drip irrigation system
