A field experiment was conducted on a sandy soil conditions at El-Khtara Farm, Sharkia Governorate, Egypt, during the growth season of 2016-2017 to study the effect of phosphorus fertilization from different sources i.e. rock phosphate (RP), ordinary super phosphate (OSP) and triple super phosphate (TSP) and phosphorus solubilizing bacterial inoculation i.e. Rhizobium leguminosarum, Bacillus megaterium (as phosphate-solubilizing bacteria) and Glomus fasciculatum (as phosphate-mobilizing fungi) on nutrients content and yield of faba bean (Vicia faba L.). All P sources were applied at the rate of 37 and 74 kg P ha^-1. Results showed that the application of different phosphate fertilizers as individual application or after inoculated with phosphorus solubilizing bacterial gave an increasing in nodules numbers plant^-1, nodules dry weight plant^-1, phosphatase activity, biomass plant^-1, yield, protein, N, P content of faba bean plants as well as  available N and P compared to untreated soil. The highest values of studied attributes were obtained with TSP at 74 kg P ha^-1application and G. fasciculutum inoculation.
