A field trial was conducted at El-Gemmeiza  Agricultural Research Station Elgharbia Governorate, Egypt, during the two successive seasons of 2017/2018 and 2018/2019 to study the response of faba bean (Vicia faba) to inoculation with Rhizobium leguminosarum, rhizobacteria Bacillus polymyxa [as plant growth promoting rhizobacteria (PGPR)] either solely or in combination and foliar spraying of boron (B), molybdenum (Mo) either alone or in combination and their effect on nodulation, growth and productivity. Results could be summarized as follows: Inoculated faba bean plants with Rhizobium leguminosarum + Bacillus polymyxa obtained the maximum values of plant height, leaf area index, total dry matter plant^-1, crop growth rate, pods number plant^-1, seed yield plant^-1, 100-seed weight, seeds and straw yields/fad, as well as number and dry weight of nodules, total chlorophyll of leaves, phosphorus, nitrogen and protein of seeds. The foliar spraying of 30 ppm B + 15 ppm Mo on faba bean plants gave the maximum values for plant height, leaf area index, total dry matter plant^-1, crop growth rate, pods number plant^-1, seed yield plant^-1, 100-seed weight, seeds and straw yields/fad, as well as nodules number and dry weight, total chlorophyll of leaves, phosphorus, nitrogen and protein of seeds. inoculated faba bean plants with Rhizobium leguminosarum + Bacillus polymyxa plus foliar spraying by 30 ppm B + 15 ppm Mo obtained the highest values for all mentioned traits, such treatment increased seeds and straw yields as well as protein content of seeds by 42.92, 33.08 and 21.32%, respectively compared to control.
