520 _aThis studl' was carried out to evaluate the influence of inoculation with nitrogen fixing bacteria(Azotobacter and Azospirillum) that were isolated from onion rhizosphere. The isolates were applied in field experiment to investigate the effect of inoculation wilih Azotobacter and Azospirillum, on Nnrogenase activity. Isolation and enumeration of Azotobacter and Azospirillum from the soil of onion plants were studied and determination of the enzymatic activnies of nitrogen fixing bacteria (nnrogenase) that were isolated from the soil ot onion plant dUring the growing periods at 0, 30, 60, 90, 120 and 150 days after sowing and selected active isolate of Azotobacter and Azospinillum. The obtained results revealed increases in Azotobacter and Azospirinllum numbers as well as nitrogenase activity in rihizosphere onion regions.
