Abstract :
In order to investigate the effect of irrigation stress and micronutrient foliar application on yield and yield components of two cultivars of bean, a factorial experiment with factorial experiment in a randomized complete block design with three replications at Islamic Azad University of Takestan, Iran was done. Experimental treatments consisted of two levels of irrigation (I1: normal irrigation and I2: discontinuation of irrigation after podding stage) and micronutrient spraying at four levels (M1: Mn: M2: Zn, M3: Manganese + Zn foliar spray, M4: Foliar spray (control) and Bean Chitti cultivar at two levels (V1: Khomein and V2: Talash). The amount of micronutrients was consumed at a concentration of 1 liter in 100 liters of water (1: 10 ratio). Three sampling stages during the growing season and one sampling at physiological maturity and harvest time of the bean plant were carried out to evaluate the effect of experimental treatments on some growth traits of chickpea bean. The results showed that the simple effects of irrigation and micronutrient fertilizer had no significant effect on leaf traits, leaf area index, leaf dry weight and leaf dry weight during the growing season. Leaf and leaf weight were significant at some sampling stages. Among the micronutrients, foliar application of Mn and Zn in most of the studied traits was better than single application. Also, there was no significant difference between Khomein and Talash cultivars in most of the stages but in some stages Khomein cultivar was more than Talash.
