A pot experiment was conducted to asses the effect of phosphorus management in summer mungbean irrigated with sodic water during 2013. Three levels each of sodic water (control, 3.0 and 6.0 mmol/L), and phosphorus (control, 15 and 30 mg/kg of soil, were tested in complete randomized design with three replications. The results indicated that application of irrigation water having RSC 1.0 mmol/L and phosphorus 30 mg/kg of soil recorded the maximum and significantly higher total and available phosphorus, dehydrogenase enzyme activity and alkaline phosphorus activity over rest of the treatments. However, pH, EC and ESP did not show any significantly difference under different levels of phosphorus.
