A field experiments was conducted at farmer’s field village basoda (Vidisha) during kharif seasons 2018-19 to study the possibility of improving the microbiological fertilizer for soybean by seed inoculation with Rhizobium and plant growth promoting rhizobacteria alone and in combination using soybean cultivar JS 95-60. Their residual contribution was assessed on productivity of succeeding wheat (Tritium aesivum L.) at three levels of N and soil properties. The trial was set up in randomized block design with seven treatments and four replications. Rhizobium sp. alone gave significant increase in nodules number (74 %), nodules dry weight (485 mg/nodules), seed yield (27.5qha-1) leaf area index (14.5) and harvest index (49.5%) over the uninoculated control. The PGPR alone gave significant increase in nodule number (73.5%), nodules dry weight (481mg /nodules) seed yield (26.9 q ha-1) leaf area index (14.2) and harvest index (48.9 %) over the uninoculated control. Conjoint use of Rhizobium and PGPR also result in 9.6 and 12.8% increase in soybean grain and straw yields respectively over control. It is also significantly improved available N, P and K in soil by 18.7 56.7 and 17.5% respectively over the uninoculated control at the harvest. In soybean crop, the N levels PGPR and Rhizobium revealed 3.88 and 3.91 t ha-1 wheat grain yield as compared to 3.67 t ha-1 with uninoculated soybean crop. Conjoint application further increased the wheat grain and straw yields by about 9.9 % over the uninoculated soybean. Different inoculation treatments also significantly improved the various yield attributed of wheat. Dual inoculation of Rhizobium sp. and PGPR in soybean also significantly increased soil available N by 16.3% and 17.4 % and soil available P by 27.5 and 50.0% of wheat over the uninoculated soybean respectively. Increasing levels of N significant increased the wheat grain and straw yields, available N, P and K in soil at harvest.
