Abstract: Agriculture scientists made a lot of efforts to improve organic agriculture aiming food safety. For five decades until now legume inoculation by Rhizobia was successful.So it is very important to compare Rhizobia with the Effective Microorganisms (EM) inoculation as a progress in organic agriculture. Three cultivars of Faba bean were inoculated by Rhizobia and EM separated or combined. Results showed that Rhizobia still reserved their place with faba bean over EM as a single inoculum especially after 45 days for plant height, plant dry weight, number and dry weight of nodules and number of bacteria (total count and nitrogen fixing), but the combined inoculation Rhizobia with EM activated each other and scored the highest values at harvest in grain yield, NPK uptake by plant and seeds. Also, numbers of total bacteria, nitrogen fixing bacteria, fungi and actinomycets were increased in inoculated soil . Fungi and actinomycets were superior in treatments of EM solely or combined with Rhizobia. The cultivar Nubaria1 scored a highest grain yield followed by Giza716 and Sakh1 which was much related to Rizobia inoculum and attained its highest values with Rhizobia. Saving 50 % of nitrogen dressing through inoculation was a very important result .
