A field experiment was carried out during Kharif, 2020 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) on sandy loam soil to assess the effect of biofertilizers and phosphorus on growth parameters and yield of Cowpea. The design of field experiment was Randomized block design consisting of ten treatments each replicated thrice. Experimental results showed significant increase in growth parameter viz., Plant height (81.09 cm), number of branches (4.87), number of nodules (53.27), plant dry weight (30.43 g/plant), crop growth rate (12.59 g/m2/plant) and yield attributing parameters viz., pods/plant (14.73), seeds/ pod (8.85), 100-seed weight (8.02 g), seed yield (2.62 t/ha) and biological yield (9.07 t/ha) were recorded with dual inoculation of Phosphate Solubilizing Bacteria and Vesicular Arbuscular Mycorrhiza along with 55 kg phosphorus per hectare.
