Author(s): Raghuveer and JA Hosmath
Abstract: A field experiment was conducted at Main Agricultural Research Station, Dharwad on medium black soil during Kharif-2015. There were twelve treatment combinations consisted of three levels of nitrogen (20, 40 and 60 kg N ha-1) and four levels of phosphorus (40, 60, 80 and 100 kg P2O5 ha-1). Significantly higher soybean seed yield (25.77 q ha-1), haulm yield (31.32 q ha-1), net returns (72438 Rs. ha-1) and B:C ratio (3.38) recorded with combined application of nitrogen @ 60 kg ha-1 and phosphorus @ 80 kg ha-1compared to other treatments and it was on par with application of nitrogen @ 60 kg ha-1 and phosphorus @ 100 kg ha-1. Application of nitrogen @ 60 kg, phosphorus @ 80 kg and potash @ 25 kg per hectare found optimum to obtain substantial soybean seed yield.
