In recent years, due to the rapid growth of solid set sprinkler irrigation system with moving sprinklers, it is necessary to continuously evaluate and monitor the implemented systems and use the results to improve their performance in the country. In this study, the performance of a solid set sprinkler irrigation system was evaluated in the number of farms of Fars province. Based on experimental data, changing the system from surface irrigation to sprinkle irrigation reduced water consumption by 42% in the field products, and increased cropping area in region which were not under water stress. Most of the farms were located in windy areas, and the average wind drift loss was 16%. The Average amount of Christiansen uniformity (CU) was 63%. According to the distribution uniformity values, evaluated systems were classified in the three levels of unacceptable, poor, and as relatively good. The average amount of PELQ was 52% which was at unacceptable level. In general, the weakness in the design, implementation and management of selected systems were the reasons for the low values of measured parameters. Which can be specifically referred to as; irrigation in a windy climate, using of the number of sprinklers more than the design limits, using of two or three sprinklers on each wing, low quality of equipment. Considering the mentioned issues was recommended to improve the performance of irrigation system.
