Impact of inoculations of eight individual strains (CN2, CSH4, Cu35, CMS7, CSH23, CSH27, CF18, and Cu47, two combinations (Comb 4A and Comb 4B) of four Bacillus strains and mixture of all strains (Mix) was studied. Various growth and biochemical parameters of maize plant were determined in pot trials. Strain Bacillus subtilis CN2 showed 49% maximum increase in shoot length. The blend of entire strains was observed to have their lenghth increased about 21 %. Bacillus subtilis CN2 showed maximum increase 155%, in fresh biomass and 233 % increase in dry weight. Bacillus amyloliquefaciens (Cu47) and Comb 4A and showed maximum peroxidase content of 163 % and 94 % as compared to uninoculated control. Comb 4B was shown to have significant higher content of acidphosphatase (811 %). Increase in all other physical and biochemical parameters were noticed. Therefore, Bacillus strains exhibited characteristic increased potential of plant growth and can have great application in innovative agricultural practices.
