Abstract
Response of faba bean (Vicia faba L.) to co-inoculation with Rhizobium leguminosarum bv. viciae strains as a plant growth promoting and Pseudomonas fluorescens with half recommended doses of NPK was studied. Rhizobium strain RL-12612 showed significantly increased in Indole acetic acid (IAA) produced in complete and minimal medium supplemented with tryptophan in relation to bacterial strains. Whereas, PF-23932 showed significantly increased in IAA produced in minimal medium supplemented with tryptophan.  A field experiment was conducted at Tag El-Ezz Research Station, Dakahlia Governorate, Egypt during two seasons 2014 to 2015. Co-inoculation with rhizobium strains and Pseudomonas fluorescens PF-23932 improved nodulation parameters during two seasons above the uninoculated plants. All treatments showed significant increase in root dry weight at 60 days plant-old above uninoculated plants during two seasons. Whereas, all treatments appeared significant increase in plant height in 2014 season. The result revealed high significant increase in the number of pods per plant in both seasons when the plants inoculated with RL-12612 strain and co-inoculatedrhizobium strains with Pseudomonas fluorescens PF-23932 above uninoculated plants at 150 days-old among two seasons. RL-207 and co-inoculation with Pseudomonas fluorescens PF-23932 play an important role to improve chlorophyll b  at 60 days plant-old among first seasons. All treatments  appeared significant increase in NPK content at 60 days plant-old above uninoculated plants among two seasons except potassium content in second season .
