“…Symbiotically, Azotobacter and Bacillus are considered two potential PGPR species to fix atmospheric nitrogen upon inoculation to the leguminous crop plants. The non‐symbiotic species' counterpart includes Enterobacter , Gluconobacterium diazotrophicus , Azospirillium , Azoarcus , Pseudomonas , Azotobacter , Burkholderia Anabaena , cyanobacteria and Nostoc (Arora & Tiwari, 2017; Bashandy et al, 2019). Phosphorous is the second essential plant growth macronutrient, as it contributes a lot to respiration, macromolecule biosynthesis, cell signalling, photosynthesis and energy transfer (Malhotra et al, 2018).…”
