Abstract:
The present study was conducted to depict the potential role of zinc solubilizing bacteria namely BMRR126 and BMAR64 on zinc (Zn) biofortification of rice. The short-term pot experiment was performed with both the bacterial isolates, which showed an augmentation in length and weight (both fresh and dry) of the shoot and root of the plant. The highest Zn accomplishment in the shoot (17.67mg/kg) and root (33.43mg/kg) was determined in the treatment (T5) containing bacterium BMRR126 along with zinc oxide. Surprisingly, treatment T5 also augmented the level of available zinc in soil, which was determined to be 2.82mg/kg. All treatments containing zinc solubilizing bacterial inoculants showed better results compared to the control treatment (T1). Results of the current study indicate that zinc solubilizing bacteria can be exploited as potential bioinoculants for Zn biofortification of rice in a sustainable manner.
