Two Phosphate solubilizing bacterial isolates and their lacZ marked transconjugants were checked for their establishment in the rhizosphere and response on pearlmillet under pot house condition. Seed bacterization showed establishment of PSB in the rhizosphere upto 60 days after sowing. The counts were slightly higher in inoculated treatments compared to uninoculated control. Application of rock phosphate and phosphatic fertilizers increased the biomass by 35–50 per cent over control. The P-uptake also improved with soil amendments and seed inoculation at both stages of sampling.
