A field experiment was conducted in micro plots of the size 1.44m2 at experimental area of Department of Soil Science and Agricultural Chemistry in Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during Kharif, 2016 to study the combined effect of biological nitrogen fixing bacteria with phosphate solubilizing bacteria as affected by different levels of nutrients on Blackgram (Vigna mungo L.). Four levels of nutrients i.e. control, 75% SR, 100% SR and 125% SR of NPK were integrated with different bio-fertilizer viz. Rhizobium, PSB, Rhizobium+ PSB and with uninoculated. The experimental results revealed that the grain yield significantly increased by single inoculation with Rhizobium and PSB up to the level of 12.11 qha-1 and 13.40 qha-1. The dual inoculation (Rhizobium+ PSB) was also signification increased the grain yield up to level of 14.15 qha-1 in comparison to 10.63 qha-1 in uninoculants. The maximum grain yield was obtained 17.33% SR of NPK, The lowest yield was recorded 6.00 qha-1 with respective control. Seed inoculation with Rhizobium, PSB and dual inoculation with (Rhizobium + PSB) was found effective to increase number of nodules, Plant height, branches plant-1 and protein percent content. From the investigation results showed that dual inoculation and (Rhizobium+ PSB) was significantly superior in comparison to single inoculation and uninoculation respectively.
