A study was conducted to know the impact of inoculum levels on survival of inoculated P-solubilizing bacteria (PSB) on groundnut seeds and its influence on plant growth was analyzed under pot culture conditions. The survival of PSB was found to increase with the increase in inoculum level. Among different inoculum levels, 2500 g of carrier based inoculum ha-1 (for 110 kg seeds) recorded maximum population of phosphate solubilizing bacteria on groundnut seeds.  The storage of inoculated seeds for 4, 8 and 24 h after inoculation showed significant reduction in population of PSB on seeds compared to 0 h storage. However, the data on the pot culture experiment indicated that seeds inoculated with 1500 g ha-1 of carrier based inoculum significantly enhanced the nodulation, growth, dry matter content and P uptake of groundnut plants, the available P content in soil and population of phosphate solubilizing bacteria in rhizosphere over lower doses of inoculum up to 750 g ha-1 but was on par with higher doses of inoculum up to 2500 g.
