Phosphate solubilizing bacteria Bacillus subtillis, Bacillus circulans, Pantoea dispersa and Pseudomonas syringae isolated from Rhizospheres soil of coal mines landfills of Chhattisgarh, India were studied for improvement of maize crop with and without RP and crop residue during field study under agroclimatic regions. The experiment included twenty four treatments (soil; Soil + RP; Soil + RP+ RS; Soil + RP+ SB; Soil + PSB 2; Soil + PSB 5; Soil + PSB 8; Soil+ PSB 9; Soil + BC; Soil + RP + PSB 2; Soil + RP + PSB 5; Soil + RP + PSB 8; Soil + RP + PSB 9; Soil + RP + BC; Soil +RP + RS + PSB 2; Soil + RP + RS + PSB 5; Soil + RP + RS +PSB 8; Soil + RP + RS + PSB 9; Soil + RP + RS + BC; Soil +RP+ SB +PSB 2; Soil+ RP+ SB +PSB 5; Soil +RP+ SB +PSB 8; Soil+ RP+ SB+ PSB 9 and Soil+ RP+ SB + BC). The application of these bacterial strains as bio inoculants showed significant effect on maize crop yield and soil fertility. Maize crop yield was increased to 18.2% with inoculation, 16.9% with rock phosphate and 22.3% when inoculation was done with rock phosphate and agricultural waste. The present study suggest that Bacillus subtillis, Bacillus circulans, Pantoea dispersa and Pseudomonas syringae along with RP fertilization play an important role in plant growth promotion and improvement of soil fertility.
