Abstract :
To evaluate the effects of foliar application of methanol on yield and yield components of bean under drought stress, a factorial experiment was conducted based on a completely randomized design with three replications at Khatam-Al-Anbia University of Behbahan. The first factor was different levels of methanol consisting of 0 (control), 10, 20 and 30 volumetric percentage (v/v), which were applied foliarly at three times with 10 days intervals during growing season of bean. The second factor was moisture regimes with three levels of irrigation at 25, 75 and 100 percent of field capacity. Results of this study showed significant differences among levels of methanol concentrations as to dry weight of pod, pod width and length, seed length and number of pod per plant. All of the yield components were mainly decreased by severe drought stress. As a whole, application of methanol did not increase yield of bean under drought condition.
