Throughout two successive years (2018-2019 and 2019-2020), field experiments in split-split plot design with three replicates by  combining three phosphorus levels (0, 50 and 100% from recommended doses) and two addition ways of zinc (soil and foliar) half of treatments inoculated with PSB and the other half without inoculation. P fertilization individually comparing with the control (non-fertilized) on faba bean increased significantly all of vegetative growth parameters (plant height, fresh and dry weight), chlorophyll content.  P and Zn content increased in shoots and decreased in roots as well as yield and its components (seed index, weight of pods, total yield, total carbohydrates and protein) were increased and recorded the highest values at 100% RD. The results in this study showed that, foliar application with Zn-EDTA was the most suitable form significantly affected in all mentioned parameters. Also, in the same experiment found an increase in all studied parameters in inoculated plants with PSB.
