Field experiment was conducted during kharif, 2016 on sandy loam soil to study the effect of phosphorus levels, biofertilizers (PSB) and organic manures (vermicompost) on dry matter production at flowering, total root nodule number, effective root nodule number and yield of green gram. The experiment was laid out in randomized block design with three replications having 12 treatment combinations viz. 3 levels of phosphorus (0, 75 and 100 % RDP) and its integration with PSB (500 g ha-1 seed) and vermicompost (5 t ha-1). A significant increase in dry matter production at flowering was recorded with the application of 100 % RDP along with PSB and vermicompost. Application of 100% RDP ha-1 along with vermicompost and PSB seed inoculation (T12) recorded significantly highest number of total and effective root nodules plant-1 (12.63, 19.1 and 25.1 total nodules pl-1 and 6.83, 10.1 and 12.97 effective nodule pl-1 during 3rd, 4th and 5th weeks after sowing, respectively). Combined application of 100 % RDP along with PSB and vermicompost registered significantly highest grain (1626 kg ha-1) and haulm yield (1033 kg ha-1) in green gram. The treatment control (without P fertilization) showed significantly poor performance in dry matter production and yield of green gram as against the rest of the treatments.
