A field experiment was conducted during rainy (kharif) season of 2017-18 at farmers field at Sehore, (M.P), to study the effect of 8 fertilizer levels (75% RDF, 75% RDF + FYM 5 t ha-1, 100% RDF, 100% RDF + FYM 5 t ha-1, 125% RDF, 125% RDF + FYM 5 t ha-1, FYM 5 t ha-1, Absolute control) on Yield, nodulation, NPK content, uptake and its balance in two soybean varieties JS 95-60 and JS 97-52 were evaluated in factorial randomized block design with 3 replications. The grain yield was significantly higher with application of 125% RDF + FYM 5 t ha-1 (1820 kg ha-1), which was at par with 100% RDF + FYM 5 t ha-1 (1801 kg ha-1). The variety JS 95-60 recorded significantly higher grain yield (2203 kg ha-1) as compared to variety JS 97-52 (886 kg ha-1). Number of root nodules per plant and dry weight of root nodules per plant are significantly higher with the application of 125% RDF + FYM 5 t ha-1 than other fertilizer treatments. Variety JS 97-52 was better in number and dry weight of root nodules per plant than JS 95-60. The NPK content and its uptake were significantly increased with to application of 125% RDF + FYM 5 t ha-1 followed by 100% RDF + FYM 5 t ha-1. Variety JS 95-60 was also noticed significantly increased in respect of N, P and K content in straw, seed and their uptake. Application of different treatment combinations of fertilizer levels and varieties improved the available N in the soil. Phosphorus and potassium showed marginal gain in sum experimental plots.
