This study carried out to evaluate the water distribution uniformity of micro-sprinkler to improve water utilization efficiency. The water quantity and the water pressure were measured according to the spacing of micro-sprinkler and adjusting the applied water pressure. The results showed that the spacing of the micro-sprinklers a decisive influence on the distribution uniformity, but the change in hydraulic pressure did not have a significant effect. The water quantity was reduced by 22.7 ± 1.6 % when the water pressure dropped 100 kPa. Each micro-sprinkler has different spray pattern. The wetted radius was measured about 4 m. A peak was found within a meter radius from the center of the micro-sprinkler and gentle slope between 2 - 4 m. The appropriate spacing is 2 - 4 m depend on micro-sprinkler and purpose of the system. The results would be used in micro-sprinkler system guideline and design for best water distribution uniformity.
