Plant Growth Promoting Rhizobacteria (PGPR) Increases Yield and Mineral Contents of Rice by Mobilizing Nutrients in the Rhizosphere

Plant growth-promoting rhizobacteria (PGPR) are multipurpose entities in case of crop quality and yield improvement. This study evaluated the impact PGPR inoculation root zone nutrient release, rice yield, grain (P, Fe, Mn, Zn) content two popular varieties Bangladesh (viz., BRRI dhan49 Binadhan7). It was a single factor (bacterial treatment) experiment where B0, B1, B2, B3 treatments represented inoculated control, indole acetic acid (IAA) producing bacteria consortium, phosphorus solubilizing (PSB) combination B1 B2 treatments, respectively. Nutrients released pore water higher at 5 days after transplanting (DAT), compared to 25 DAT. Mostly performed significantly number tillers/pots, straw P, Fe content, all four nutrients uptake. The highest observed treatment is both Binadhan7 (42.10±1.76 g/pot) (36.20±1.57 g/pot). PSB containing bio-fortified largest amount P varieties. On other hand, stored Mn (46.70±1.30 44.30±1.37 mg/kg) (45.30±2.90 25.70±2.37 dhan49, resulted maximum Fe) uptake These bacterial isolates seemed promising for improvement an eco-friendly sustainable way.
