Abstract: Soyean (Glycie max L. Merril) is a very important oil seed and protein rich crop. It has the capacity to fix atmospheric nitrogen through root nodule bacteria in symbiosis with soybean. Most of the farmers grow soybean without fertilizer and also realize the carry over effect of legume crop on the succeeding wheat crop. The concept of integrated nutrient supply involving organic manures and inorganic fertilizers used to sustained agriculture production and maintain soil health as well as produced crop with less expenditure. Keeping the above points in view the present experiment was carried out for two years in 2016 and 2017. A field experiment was carried out at research farm, Deptt. of soil science & Agricultural chemistry, JNKVV, Jabalpur (M.P.) during Kharif seasons. The experiment consisted of eleven treatment combinations (T1- FYM 6 t ha-1 Enriched with PSB & Rhizobium, T2- FYM 4 t ha-1 Enriched with PSB & Rhizobium + Remaining of RDF through chemical fertilizer, T3- FYM 2 t ha-1 Enriched with PSB & Rhizobium + Remaining of RDF through chemical fertilizer, T4- Vermicompost 2 t ha-1 Enriched with PSB & Rhizobium, T5- Vermicompost 1.5 t ha-1 Enriched with PSB & Rhizobium+ Remaining of RDF through chemical fertilizer, T6- Vermicompost 1.0 t ha-1 Enriched with PSB & Rhizobium + Remaining of RDF through chemical fertilizer, T7-Poultry Manure 2 t ha-1, T8-Poultry Manure 1.5 t ha-1+ Remaining of RDF through chemical fertilizer, T9- Poultry Manure 1.0 t ha-1+ Remaining of RDF through chemical fertilizer,T10-100 % of RDF NPK (25:60:40 kg NPK ha-1) and T11 Absolute control. Amongst the INM treatments, T5 (Vermicompost 1.5 t ha-1 Enriched with PSB & Rhizobium+ Remaining of RDF through chemical fertilizer) resulted in higher grain and straw yield, maximum number of root nodule formation plant-1 as well as their dry weight at every stage of plant growth. At 60 DAS maximum root nodules were 23.9 plant-1 as against only 14.4 plant-1 under control treatment. Similarly the dry weight of root nodules at 60 DAS was 46.3 mg plant-1 as against only 22.3 mg under control treatment.
