This study clearly showed the benefit of P availability in combination with Rhizobium on leaf area, leghaemoglobin content, nitrate reductase activities of leaves and nodules, fresh and dry weight of nodules and fresh weights of stem + leaves at vegetative and flowering stages. Yield components, pod number and seed number were significantly increased by P availability by fertilizer alone and in combination with Rhizobium or through Rhizobium +Microphos. Seed test weight and number of seeds clearly demonstrated the benefit of rhizobium and microphos (P-solubilizing bacteria) inoculation in organic farming of legumes and cost saving of crop production in terms of inorganic fertilizer production. The study demonstrated that the inoculants are suitable for mass production and commercialization for improving crop yield. Microphos work slowly for P liberation from organic and inorganic pools, improved nitrogen fixation efficiency, help in development of extensive root system bearing maximum number of nodules by sustained availability of P from the soil conditions used for growing control plants. Improved crop yields components and nodulation response of plants exhibit that phosphate solubilizing bacteria can be successfully used in combination with N2 fixing symbiont to ensure the most efficient use of least mobile and limited supplies of rock phosphate fertilizer.
