Irrigation performance evaluation is needed for hydrological planning and as the first step to improve water management, one of the performance evaluation criteria is the relative annual irrigation supply index (ARIS), which is used in agriculture and water resources management to evaluate the adequacy of water supply for irrigation in the length of a cropping period is used. Therefore, the purpose of this research is to investigate the ARIS index and water productivity indices for different plants (wheat, seed corn, corn, maize, sugar beet, cotton, alfalfa and soybean) in two surface and center pivot irrigation systems in It was Moghan Plain where three indices 〖WP〗_T، 〖WP〗_eg and 〖WP〗_en were used to check water efficiency. This research was conducted in 13 combinations of irrigation system - crop in the area of 647 hectares. The results showed that the ARIS index for the studied area varied from 0.73 to 2.21, so that the overall average was 1.27 with an overall standard deviation of 0.15, which indicated the application of heavy irrigation in the fields. Regarding the irrigation systems, the average ARIS for surface and center pivot irrigation was 1.60 and 0.89, respectively. Also, in terms of plant type, soybean and corn had the lowest and highest ARIS values with 0.73 and 1.73, respectively. On the other hand, the investigation of technical and economic efficiency of water for main crops and irrigation systems showed that maize and seed corn and cotton in the surface irrigation system had the lowest value,
