A field experiment was conducted in Jobner, Rajasthan, India during the rainy season of 1998 to investigate the effect of P fertilizers (at 0, 15, 30, 45 and 60 kg P2O5/ha) and biofertilizers (Rhizobium sp.; phosphate solubilizing bacteria, PSB; and combination of of Rhizobium + PSB) on the growth and yield of mung bean cv. RMG 62. All biofertilizer treatments increased growth and yield characters, except pod length and test weight. The highest values for all the parameters studied were obtained with Rhizobium + PSB: dry matter accumulation/m row at 50 days after sowing and at harvest; branches/plant at harvest; number of nodules per plant; pods/plant; and seed yield/ha. The dry matter accumulation, pods/plant, number of seeds per plant, test weight and seed yield were highest with P at 45 kg P2O5/ha than the other P rates.
