The effects of water deficit on concentration of macro and micronutrients of common bean (Phaseolus Vulgaris,.) cultivars

Water deficit is one of the main restrictions to crop growth and productivity worldwide. This study was conducted to investigate the effects of different levels of water deficit (Ii.oo:100%-control of field/pot capacity, Io.7s:75% of field/pot capacity and Io.so:50% of field/pot capacity) on the concentration of macroand micronutrients of four common bean (Phaseolus vulgaris L.) cultivars ("Sankiz", "Sazova", "Kirk Gtinluk", and "Gina"). The investigation was carried out in pot experiment in a greenhouse and experiments were designed using a randomized block design with ten replications. Water stress significantly but differentially affected the growth, seed yield components and nutrients of the four common beans in our study. In the fresh pod, cv."Gina"has come to the fore in terms of macro and micro elements (P, K, Ca, Mg, B, Cu, Mn, and Se) under the maximum water stress (Io 5 o ) . Similarly, cv."Gina"was released mainly foreground in terms of growth parameters (pod width, pod length, number of pods in the plant and number of seed in the total plant) and macro- and micronutrients in terms of P, Cu, F and S under the maximum water stress (Io.5o). Based on the results of this study, it can be said that cv. "Gina"is more tolerant to water stress than other bean cultivars. The use of drought-tolerant cultivar of common bean may produce more yield with less water; thereby improves water productivity for efficient use of water resources.
