Effect of treated wastewater irrigation on some physiological characteristics and nutrition of pinto bean

Due to the limited available water resources and the other hand, population growth and increasing water demand use of any solution to save water and increase the area under cultivation is of utmost importance. This study was to evaluate the effect of irrigation with treated wastewater on some quantitative and qualitative characteristics of pinto beans number G-01437. The experiment was laid out in a randomized block design with four levels (0, 50, 75 and 100 percent sewage). Results indicated that irrigation with completely wastewater increased plant height, and fresh and dry weight products by 17.6, 22.5, and 18.1 percent in compare to control, respectively. The most concentration values of chlorophyll a, b and the total was associated with 100% irrigation with wastewater. In the meantime, irrigation with increasing level of wastewater increased the absorption level of N, P and K in compare to control. So, even with relatively low use of wastewater was significantly increased the performance of this product. Use of sewage, in addition to permanent monitoring of their quality were recommended.
