To evaluate the effect of different irrigation methods on yield and water use efficiency (WUE) of chitti beans, a research study was conducted in 2022 and 2023 at the Bean Research and Education Center in Khomein, Iran. The study was designed as a multi-location (regional) experiment using a randomized complete block design with three replications. Four irrigation methods included classical sprinkler irrigation, New-fit sprinkler irrigation, rain flat irrigation, and drip tape irrigation. Different types of chitti bean cultivars (line 21492, Kousha, and Saleh) with three growth habits were randomly sown in these locations. The results showed that the maximum water consumption (12500 m3 ha-1) belonged to the classical sprinkler irrigation method, while the least (6600 m3 ha-1) was in the drip tape irrigation; and the New-fit sprinkler and Rain flat irrigation had almost the same water consumption (about 11000 m3 ha-1), were in between those two methods. Also, the highest and lowest WUE (0.45 and 0.18 kg m-3, respectively) were obtained in drip tape and classical sprinkler irrigation, respectively. The results of analysis variance showed that the irrigation method effect on yield components and grain yield was significant, but the effect of cultivar was significant only on grain yield. The highest (296.9 g m-2) and the least (228.7 g m-2) values of grain yield were observed in the drip tape and classical sprinkler, respectively. Among the cultivars, the highest grain yield belonged to Kousha and Saleh cultivars. In general, the results demonstrated that the drip tape not only decreased water consumption but also led to improving yield components of chitti bean and higher water use efficiency.
