Abstract
Common bean is an important crop in Chaharmahal and Bakhtiari province with high water requirement and in recent years, due to water scarcity, its cultivation has declined sharply. In this experiment, deficit irrigation with change irrigation method in bean cultivars were investigated. Factorial experiment was conducted in a randomized complete block design with three replications in 2016 and 2017 at Chahartakhte Research Station in Shahrekord region. Cultivar with three levels (Koosha chitti bean, Yaghut ​​red bean and Dorsa white bean) and irrigation method with three levels (strip-drip irrigation, furrow irrigation, and conventional (flood) irrigation (strip surface irrigation)) were used in this experiment. Combined analysis results showed that plant height, grain yield, yield components, and water productivity were affected by bean cultivars and irrigation methods. The highest grain yield was obtained from Yaghut red bean cultivar, which had a significant difference with Koosha chitti bean cultivar. The highest water productivity was obtained from Yaghut red bean cultivar, which had a significant difference with other common bean cultivars. The highest water productivity was obtained from strip surface irrigation, which did not have a significant difference with strip drip irrigation, while water use in strip drip irrigation was far less than strip surface irrigation. Therefore, it is possible to use drip irrigation with less water consumption.
