Abstract: In this study, the effects of different zeolite doses (Z0:0, Z3:30, Z6:60, Z9:90, and Z12:120 t ha−1) and water levels (I50: 0.50, I75: 0.75, and I100:1.00) on yield, quality, and nutrient absorption of common bean were evaluated under arid conditions in Karapinar Konya, Turkey, in 2011 and 2012. The experiment was carried out in a split-plot design with three replications. The results showed that in each treatment different doses of zeolite together with changes in the rate of irrigation levels effected yield and yield components. Water use efficiency was also affected by zeolite and irrigation treatments. The highest yields, 4777 and 4114 kg ha−1, respectively, were obtained from the Z9I100 application in 2011 and 2012. During the experimental years, water consumptions at the same treatment were determined 451 and 468 mm, respectively. In addition to this, zeolite treatments affected the contents of N, K, Zn, Mn, and Cu in leaf samples (p < 0.05). These nutrient levels increased with raising zeolite doses.
