Abstract: A field experiment entitled, “Performance of summer soybean (Glycine max. L. Merrill) to fertilizer levels and plant densities for seed production†was conducted at PG Research Farm, Agronomy Section, R.C.S.M. College of Agriculture, Kolhapur during summer 2017 to evaluate different treatments on nutrient status and soil properties. The treatments consisting of three fertilizer levels (37.5:56.25:33.75 NPK kg ha-1 i.e. 75% RDF, 50:75:45 NPK kg ha-1 i.e. 100% RDF and 62.5:93.75:56.25 NPK kg ha-1 i.e.125% RDF) and three plant densities [1,48,148 plants ha-1 (45 x 15 cm2), 2,22,222 plants ha-1(45 x 10 cm2) and 4,44,444 plants ha-1(45 x 5 cm2) ]. Mean N, P and K content in seed and straw, total uptake of N, P and K and available N, P and K was influenced significantly by different fertilizer level as well as plant densities. The mean N, P and K content, total N, P and K uptake and available N, P and K were maximum with application of 125% RDF followed by 100% RDF. Mean N, P and K content in seed and straw was recorded highest in, 48,148 plants ha-1 (45 x 15 cm2) followed by 2,22, 222 plants ha-1 (45 x 10 cm2) The uptake of N, P and K in soybean was highest in plant density 4,44,444 plants ha-1 (45 x 5 cm2) followed by 2,22, 222 plants ha-1(45 x 10 cm2). Numerically available NPK in soil was increased with increase in fertilizer levels. It was higher at 125% RDF than fertilizer level 100% RDF. Highest available N, P and K was recorded highest in 1, 48, 148 plants ha-1 (45 x 15 cm2) followed by 2, 22, 222 plants ha-1(45 x 10 cm2). The seed yield were highest with application of 125% RDF (27.44 q ha-1) followed by 100% RDF (25.99 q ha-1). The plant density 4,44,444 plants ha-1 (45 x 5 cm2) produced highest seed yield (27.94 q ha-1) and it was followed by plant density 2,22,222 plants ha-1 (45 x 10 cm2) (25.64 q ha-1). Protein content and oil content in seeds of soybean was significantly highest in125% RDF and in 1, 48, 148 plants ha-1 (45 x 15 cm2) treatment.
