The bioinoculants used in previous studies are commonly screened and isolated from rhizosphere and commonly known as plant growth promoting rhizobacteria (pgpr) these pgpr promote plant growth and suppresses disease incidence which is solely resulted due to the synergistic effect of nutrients and phytohormones produced by these bacteria [10–12. Screening of rhizobacteria that show multiple pgp traits suggests that they have better potential for greenhouse and field testing and applications in improving the yield of maize therefore, future investigations include the application of maize plants inoculated with these most promising pgpr in field conditions. Among the ten soil samples taken from ten different locations, fifty bacteria were isolated out of these fifty only twenty five (50%) were found to be 1-aminocyclopropane-1-carboxylic acid (acc) deaminase positive having the ability to use 1-aminocyclopropane-1-carboxylic acid (acc), the precursor of ethylene, as sole nitrogen source these bacterial isolates were identified as klebsiella.
