Two pot experiments were conducted to evaluate the response of wheat (Giza 168) and faba bean (Giza 717) grown in sandy soil to the inoculation with Azotobacter spp., Baollus spp., Azospirillum spp. and Rhizobium leguminosarium. Results indicated that inoculation with different nitrogen fixing bacteria showed significant Increases in nitrogenase activity in the rhizosphere of inoculated wheat plants and in faba bean nodules at half dose of nitrogen fertilizer (7.5 kg N/fed). Nitrogen fixing bactena significantly increased the dehydrogenase enzyme activity (DHA) in the rhizosphere soil compared to un-inoculated control in both plants. Wheat yield significantly increased with mixed inoculants + 120 kg N/fed as compared with the other treatments. Inoculated by Bacillus spp. + Rhizobium leguminosarium with 15 kg N/fed showed highly significant Increase in grain yield of faba bean (42.5 g/plant).
