Then 24 pots were provided & filled with sterile soil. In 12 pots the pepper seeds inoculated with isolated Bacillus and the rest were remained as test groups. After 80 days the pots were evaluated. Furthermore, the isolated bac- teria from soil of pots were evaluated for indole acetic acid and ammonia production. The data were statistically analyzed using SPSS version 16.

Results: The pots, which inoculated with isolated Bacillus, showed more growth regarding to the number of leaves, bush height, stem diagonal and root lengths than the tests. …
