The aims of this study were to boost growth attributes, yield and nutrient uptake of rice by different
treatment combination of plant growth promoting rhizobacteria (PGPR) and various phosphorus fertilizer doses. PGPR strains e.g. Pseudomonas aeruginosa BHUJY16, P. aeruginosa BHUJY20, Pseudomonas
putida BHUJY13, P. putida BHUJY23 and Pseudomonas fluorescens BHUJY29 were known as combined
Pseudomonas culture (CPC). The treatment combinations of (CPC + Azotobacter chroococcum + Azospirillum
brasilense + 60 kg ha
−1
P2O5) and (CPC + A. chroococcum + A. brasilense + 30 kg ha
−1
P2O5) showed greater
significant (31.66 and 32.00 g pot
−1
) and (29.99 and 30.28 g pot
−1
) grain yield of rice as compared to
control during first and second year pot experiments, respectively. The treatment combination (CPC + A.
chroococcum + A. brasilense + 60 kg ha
−1
P2O5) was recorded significantly higher plant growth attribute,
yield, nutrient contents in grain and straw of rice followed by combination of (CPC + A. chroococcum + A.
brasilense + 30 kg ha
−1
P2O5), (CPC + A. chroococcum + 60 kg ha
−1
P2O5) as compared to control during both
year of experiments. PGPR combination with 60 kg ha
−1
phosphorus (P) was found higher growth and
yield; while PGPR with 30 kg ha
−1
P gave approximately similar results of growth and yield due to more
availability of NPK in the soil by cumulative effect of PGPR activities in the rhizosphere soil. So that
treatment combinations of PGPR with 30 kg ha
−1
P was found economically cheaper than the PGPR with
60 kg ha
−1
P. Hence, the treatment combination of PGPR strains of Pseudomonas culture with A. chroococcum + A. brasilense + 30 kg ha
−1
P2O5 may be used as more effective combination for rice production
