Co-Inoculation of Rhizobium and Azotobacter on Growth of Faba bean under Water Deficit Conditions

6 Abstract: Biofertilizers can be expected to decrease the use of chemical fertilizers. The effects of native Rhizobium legominosarum bv viciae strain F46 and Azotobacter chroococcom strain AGO11 inoculation and nitrogen fertilizer was studied on growth and yield of faba bean (Vicia faba L.) in deficit irrigation. The trial was conducted as a split plot factorial experiment in Agricultural Research Station of Boroujerd. Co-inoculation of Rhizobium and Azotobacter increased total nitrogen content, nodulation, seed yield and biological yield under water deficit condition. Hence it can be suggested that co-inoculation of Rhizobium Legominosarum and Azotobacter chroococcum can improved some of growth indices under drought conditions.
