Drip irrigation is a affordable irrigation under structured cultivation. Drip irrigation system with high uniformity can be achieved through effective design, maintenance and management of irrigation systems. Nevertheless the design guidelines have not been established for the drip irrigation system products in domestic and imported considering cultivation method and greenhouse environment in Korea.
The objectives of this study were to evaluate the performance of drip irrigation system with uniformity through an experiment. The experiment was conducted to study with nine different types of emitters produced in domestic and imported. Hazen-Williams coefficients were also estimated for the drip emitter through hydraulic simulation for design use. It was found that approximately 91.5 % for 10cm emitter spacing and 96.2 % for 30 cm emitter spacing of statistical uniformity were observed in respectively. Average emission uniformity was decreased as the reduction of emitter spacing. The results would be used in the drip irrigation system design and guideline construction.
