Microbial Biofortification of Zn by Plant Growth Promoting Microorganisms in Wheat (Triticum aestivum)

A lab experiment was conducted during 2021 and field experiment was conducted during the Rabi seasons of 2021 and 2022 to study the biofortification of Zn by plant growth-promoting microorganisms in wheat (Triticum aestivum). The results emerged from the lab experiment indicated that Pseudomonas striata, Bacillus megaterium and Trichoderma viride showed significantly highest colony diameter, clearing zone, halozone diameter, solubilization index and solubilization efficiency. Biofortification of zinc i.e. highest increase zinc content in grain and in straw over control and only RDF was reported in treatment T8 i.e. RDF + Azotobacter chroococcum + Pseudomonas striata (19.52 and 15.76 percent respectively)
