In the present study, different rhizosphere soil samples of vegetable fields were collected from Varanasi region and soil microbes were isolated. Total 50 isolates were screened. Out of 50 strains, 14 strains have screened and characterized on the basis of morphological, biochemical and plant growth promoting activities. Five effective isolated strains (IESDJP-DIC3, IESDJP-DIC4, IESDJP-DIC7, IESDJP-DIC8 and IESDJP-DIC12) and two known microbial strains (Azosprillum brasilense IARI-1 and Paenibacillus polymyxa BHUPSB17) culture were selected on the basis of PGPR properties. The thirty treatment combinations were prepared with seven microbial culture. The seasonal vegetable like lobia (Vigna unguiculata) varieties kasha kanchan was selected for pot trials. The seed inoculation (5ml culture with each treatment volume and 108cfu/seed) of lobia with thirty treatments have been performed and recorded very good result in pot experiment regarding plant growth, branching, flowering and fruiting. The effective treatment combination T3, T10, T11, T13, T14, T15, T16, T17, T18, T19, T21, T22, T25, T26, T27 and T30 were found for enhancing plant growth attributes, yield, nutritional content and soil properties as compared to control and others. The microbial consortia of treatment T17 (IESDJP-DIC3 + IESDJP-DIC4 + IESDJP-DIC12), T18 (IESDJP-DIC3 + IESDJP-DIC4+ Azosprillum brasilense), T19 (IESDJP-DIC3 + IESDJP-DIC4+ Paenibacillus polymyxa), T21 (IESDJP-DIC3 + IESDJP-DIC7+ IESDJP-DIC12), T22 (IESDJP-DIC3 + IESDJP-DIC7+ Azosprillum brasilense), and T27 (IESDJP-DIC3 + IESDJP-DIC8+ Azosprillum brasilense) have found more effective microbial consortium for labia production under sustainable agricultural practices. The indigenous climate resilient microbial consortium is a mixture of both plant growth promoting rhizobacteria and fungi. This microbial consortium will be cost-effective, environment-friendly and socially acceptable. This microbial consortium can replace 20 to 50% chemical fertilizer and pesticide application. This will improve plant growth, productivity, and nutritional quality as well as soil productivity.
