Abstract:

To investigate the effect of phosphate fertilizer on growth and yield of mung bean under the sewage water and applied concentration of Cadmium and Nickel an experiment was carried out at Department of Soil and Environmental Sciences, Gomal University, Dera Ismail Khan. Cadmium and Nickel concentration was applied at 12 and 20 mg kg-1 and sewage water was applied as source of irrigation in the respective pots. While phosphatic fertilizer was applied at the rate of 0, 30, 60 and 90 kg P ha-1 as Single super phosphate. The experiment was designed as complete randomized, each treatment was replicated three times. Concentration of Cd and Ni was measured in sewage water before the experiment, after harvesting Cd and Ni concentration was analyzed in shoot, root and soil. Cadmium accumulation in root and retention in soil was highest in T4 (90 kg P ha-1), similarly Ni accumulation in shoot was highest in T4 (90 kg P ha-1). Concentration of sewage water, Cd and Ni have showed significant (P<0.05) effect on plant height (cm) and root length (cm). Treatments of phosphate fertilizer has exhibited statistically significant effect on plant height (cm), pod length (cm), number of seeds pod-1 and seed yield of plant. The interaction between metal × Phosphatic fertilizer was significantly recorded for root length, number of seeds pod-1, pod length and 10 seed weight. It may be concluded from the study that application of phosphate level showed significant increase in the Cd in plant root and soil. While for Ni it was found non – significant. The increase in the seed yield by the application of phosphatic fertilizers has revealed that the metal stresses have been combated by the use of fertilizer.
