Deciphering behavioral changes in maize plants in a quest to identify species specific plant growth promoting rhizobacteria

One of the most significant cereal crops in the world, maize (Zea mays L.), is used for food, feed, and energy. Inoculation with plant-growth-promoting rhizobacteria (PGPR) could be offered as a substitute method for maize production that is sustainable in contemporary agricultural systems and would reduce the need of chemical fertilisers and pesticides. In this study, we made an effort to collect enough information to support our assertion that the best PGPRs for the maize crop specifically are Azospirillum lipoferum, Pseudomonas fluorescens, Pseudomonas putida, and Bacillus subtilis. On maize crops of the AXE* and PMH1 varieties, PGPRs (Azospirillum lipoferum, Pseudomonas fluorescens, Pseudomonas putida, and Bacillus subtilis) are found to have a significant growth-promoting effect. Results showed that compared to control, A. lipoferum, B. subtilis, P. putida, and P. fluorescens treatment improved morphological, biochemical, and harvest characteristics. We have proposed with the aim of gathering more evidence that Pseudomonas putida and Azospirillum lipoferum bacteria can be deemed maize specific PGPR since out of all the strains under research, better results were obtained with these two strains.
