Micro-sprinkler irrigation has gained considerable importance in recent years for efficient utilization of water resources. Ideally, all micro-sprinkler in the system should discharge equal amount of water. It is necessary to test micro-sprinkler for its uniformity and distribution efficiencies so that the user can select the best suitable micro sprinkler and a system can be designed accordingly. In this study, field experiments were carried out to test the commercially available micro-sprinkler for the parameter such as uniformity coefficient, distribution uniformity, average application depth and sprinkler discharge. The performance evaluation was carried out at varying height and operating pressure such as 1 m and 1.5 m and 1.5 kg/cm2 and 2 kg/cm2 respectively. They were placed at linear as well as point arrangement during the test run and operated at open field condition and the wind speed during the test run was also measured. The results revealed that the uniformity coefficient was maximum at lower riser height and it was also found that the uniformity coefficient decreased with increase in the wind speed. Further comparing the results obtained from point arrangement and linear arrangement showed that the higher uniformity was obtained by point arrangement than the linear arrangement.
