Abstract: The objective of this study was to evaluate the performance of handmoved sprinkler irrigation systems under semi arid climate conditions by means of field tests conducted in Cumra-Konya (Turkey). The study was done in the sugar beet and dry bean fields irrigated by sprinkler irrigation. Catch can tests were performed to determine the performance of irrigation applied with sprinkler irrigation systems in field conditions. The main factors affecting water application and evaporation and drift losses with these systems were analysed. A set of performance guidelines and recommendations for the design and management of sprinkler irrigation is presented to attain the highest uniformity and efficiency in water application in arid and semi arid areas. In evaluation of performance was considered Christiansen Coefficient of Uniformity (CU) and the potential application efficiency of the low quarter (PAElq). The results of field tests indicated that the average CU for 10x10 m and 10x15 m sprinkler spacing was 86.7 and 80.6%, respectively. For the same spacings, the average PAElq was 70.6 and 62.4%.
