Effect of sodic water, biofertilizer and phosphorus on physical properties of soil, yield attributes and yield of mungbean

Abstract

A pot experiment was conducted to asses the effect of phosphorus management and biofertilizer in
mungbean irrigated with sodic water during 2013. Three levels each of sodic water (control, 3.0 and
6.0 mmol/L), biofertilizer (control, PSB and PSB + VAM) and phosphorus (control, 15 and 30 mg/
kg of soil), were tested in factorial randomized block design with three replications. The results
indicated that application of irrigation water having RSC 1.0 mmol/L, biofertilizer viz. PSB + VAM
and phosphorus 30 mg/kg of soil recorded the maximum and significantly higher total and available
phosphorus, dehydrogenase enzyme activity, alkaline phosphate activity, total and effective nodules,
nodule index, number of pods per plant, grain yield, straw yield and biological yield of mungbean
over rest of the treatments. A application of irrigation water having RSC 6.0 mmol/L recorded
significantly higher pH, EC and ESP as compared to other treatments. However, pH, EC and ESP
did not show any significantly difference under different levels of phosphorus and biofertilizers.
