Abstract
This study 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 with Azotobacter and Azospirillum, on Nitrogenase activity . Isolation and enumeration of Azotobacter and Azospirillum from the soil of onion plants were studied and determination of the enzymatic activities of nitrogen fixing bacteria (nitrogenase) that were isolated from the soil of onion plant during the growing periods at 0, 30, 60, 90, 120 and 150 days after sowing and selected active isolate of Azotobacter and Azospirillum. The obtained results revealed increases in Azotobacter and Azospirillum numbers as well as nitrogenase activity in rhizosphere onion regions. Also these activities reflect on onion plant productivity. This study recommended the application of Azotobacter and Azospirillum as inoculants in onion plant productivity.
