Abstract
The Effect of Water Stress on Nutrient Elements in the Leaf and Soil of Common Bean (Phaseolus vulgaris L.)
Water resources are a scarce and limiting factor for expanding cultivation and plant production in many arid and semi-arid areas. This study was conducted to investigate the effects of different water deficit levels on soil and plant concentration of macro and micro nutrients of four common bean cultivars under different water deficit conditions and was carried out in a pot experiment in a greenhouse. The treatments consisted of three irrigation regimes (I1.00, I0.75 and I0.50), to which 100%, 75% and 50% of depleted water from field capacity soil level of the pot were applied to I1.00, I0.75 and I0.50 and four varieties (Sarıkız", "Sazova", "Kırkgünlük” and "Gina). It was determined that the amount of macro and micro nutrients in the I1.00 irrigation regime was excessive, the decreases in the amount of nutrients in the I0.50 irrigation regime. The highest values of the macro and micro parameters in the soil under the highest water constraint were obtained in "Gina". However, the highest values in the "Sazova" were obtained in terms of micro elements in the leaf, and the highest values were obtained from the "Gina" in terms of macro elements in the treatments of the highest water constraint. As a result, based on the data obtained in this study, it may be stated that "Gina" is more tolerant to water stress in comparison to the other varieties in the pot experiment.
