Abstract
To evaluate the effect of different irrigation methods on the amount and efficiency of water consumption and yield 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. The irrigation methods were categorized into four treatment levels: classical sprinkler irrigation, New-fit sprinkler irrigation, rain flat irrigation, and drip tape irrigation. Different types of chitti bean cultivars (line 21492 and Kousha and Saleh cultivars) with three growth habits were randomly sown in these locations. The experimental results showed that the most water consumption (12500 m3 ha-1) belonged to the classical sprinkler irrigation method. The least water consumption (6600 m3 ha-1) was also observed in the drip tape irrigation method, and the New-fit sprinkler and Rain flat irrigation methods, which had almost the same water consumption (about 11000 m3 ha-1), were placed between the two high-consumption and low-consumption methods. Also, the highest and lowest values of water consumption efficiency (0.45 and 0.18 kg m-3, respectively) were obtained in drip tape and classical sprinkler irrigation methods, respectively. The results of data 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 irrigation and classical sprinkler irrigation, respectively. Among the cultivars, the highest grain yield belonged to Kousha and Saleh cultivars. In general, the experiment results demonstrated that the drip tape irrigation method not only decreased water consumption but also led to improving yield components of chitti bean and higher water use efficiency.
