Abstract
A field experiment was conducted during 2018-19 to study the effect of phosphorus, FYM and bio-fertilizer on nutrient content in soil before and after harvest of summer greengram. There were twelve treatments comprising of three phosphorus levels [Control (P0), 20 kg P2O5 ha-1 (P1) and 40 kg P2O5 ha-1 (P2)] combined with two FYM levels [control (F0) and 5 t FYM ha-1(F1)] along with two levels of bio-fertilizer [control (B0) and PSB inoculation (B1)]. Phosphorus applied in the form of SSP and PSB as seed inoculation. The experiment was laid out in factorial RBD with three replications. The recommended dose of N was applied uniformly to all the treatments. Residual availability of P increased due to phosphorus and PSB inoculation. Major and micro nutrients availability in soil was increased due to FYM treatment after harvesting. Organic carbon content was favourably influenced by FYM treatment. Interaction of P x F x B had synergistic effect on residual availability of P.
