Abstract: In this study, comparative indicators, which provide comparable analysis of irrigation performance among irrigation systems, were applied on K z l rmak Basin Irrigation and system performance was evaluated. As a result of the study, based on the 1996-2000 years output per unit command area, output per cropped irrigated area, output per unit irrigation supply, output per unit water consumed, total water supply ratio, gross return on investment and irrigation ratio were determined as 45-22443 and 247-43928 $ ha 1, 0.03-2.21 and 0.05-9.75 $/m3 and 0.74-6.20, 53-8708 and 8-98% respectively.
