In order to study the effect of inculation with Mycorrhizal and Azotobacter on Seed yield and Phenological Phases of Red Bean Genotypes an experiment was performed in a farm located in Lorestan Beiranshahr in crop year 2016, The factorial experiment arranged base on randomized complete block design with four replications. Parameters studied were include inoculation with arbuscular mycorrhizal fungi species (Glomus etunicatum, G. Intraradices, G. mossea) at two levels (inoculated and no inoculated), inoculated with Azotobacter chroococcum bacteria (Azotobacter chroococcum Strain 15) at two levels: (inoculated and non-inoculated) and red bean Genotypes (Landrace Beiranshahr, Akhtar and Goli varieties). The results showed that Azotobacter effect on day to grain filling, the dual effect of mycorrhizal*genotypes on days to maturity and day to pod formation and three factor interaction on seed yield significant and positive, respectively. The highest seed yield (298.90 kg. ha-1) in effet of three factor inculation Mycorrhizal*Azotobacter*Goli varietiy with plant form progressive and unlimited growth, Obtained. Also The highest Mycorrhizal response and Mycorrhizal dependent (15.59 and 13.49 percent) respectively in Mycorrhizal and Azotobacter inculation*Goli varietiy and the lowest percentage Mycorrhizal response and dependent (3.56 and 3.43 percent) respectively in Mycorrhizal and Azotobacter inculation*Akhtar varietiy, Obtained. The results showed that the Mycorrhizal symbiosis, or mycorrhizal dependency until the Development Roots Provides It's possible for host plants Access to more levels of soil own again and the spread of absorbency levels roots network Hefei, Improved absorption of water and nutrients and ultimately result in Cause increased growth and yield Mycorrhizal plants.
