Effect of different levels of phosphorus and bio-fertilizers on yield and yield attributes of kharif soybean (Glycine max L.)

Abstract

A field research was conducted during spring season in 2019 at College of Agriculture, Baramati (Maharashtra) to find out the effect of different levels of phosphorus and biofertilizers on growth and yield of soybean. The experiment was laid out in split plot design with three replications. The main plot treatments comprised four phosphorus levels, viz., T1 (control), T2 (25Kg P2O5 ha-1), T3 (75Kg P2O5 ha-1) and T4 (75Kg P2O5 ha-1). The sub plot treatments comprised four bio fertilizer treatments viz., control (B1), Seed inoculation with Rhizobium and PSB bio fertilizers each @ 25 g kg-1 seeds (B2) PSB, (B3) Rhizobium and (B4) Rhizobium + PSB thus, there were in all sixteen treatment combinations. Application of 50Kg P2O5 ha-1 with Rhizobium + PSB soybean seeds produced maximum and significantly higher grain and stover yield over rest of the treatment combinations.
