Two field experiments were performed at 2009/2010 and 2010/2011 to study the interaction effect between biofertilizers and fusilade herbicide at (1.5 L/fed. as a recommended dose) alone and in combination with additives at (1.0 L/fed.) to enhance narrow weeds control and broad bean productivity. During the two seasons, a positive correlation was found between biofertilizers and broad bean plant height, number of branches, number of nodules, fresh and dry weight, seed germination as well as number and activity of soil microbes. Inoculated broad bean seeds with Rhizobium leguminosarum ordual inoculation with (Rhizobium leguminosarum plus Bacillus megaterium) were encourage the capability of the plants to produce vigorous vegetable growth and increasing yield productivity of broad bean than non bio-fertilized treatment. The inoculation with R. leguminosarum as a single inoculants or dual inoculants with B. megaterium increased microorganism densities and activity which reflected on broad bean growth, yield and tolerability to the stress of fusilade herbicide. During1^styear fusilade at micro rate (1.0 L/fed.) with mineral oil achieved the maximum inhibition in Phalaris minor fresh and dry weigh by 62.4 and 61.76 %, respectively comparing with untreated control. While in the 2^nd year fusilade at the same micro rate with glue achieved the highest reduction in P. minor fresh and dry weight by 45.6 and 56.3% respectively comparing with the control. The highest reduction in Staria sp. fresh and dry weigh achieved from fusilade at micro rate with mineral oil by 65.31 and 71.18(1^styear) and with rape seed oil 54.6 and 56.8% (2^ndyear) respectively than its respectable control. There's no change in seed proteins types and percentage were detected after applying fusilade on broad bean in the presence or absence of biofertilizers. While the dual inoculation proved to be the most effective biofertilizers that increase protein components at the both seasons by (12.8% and 12.04%, respectively). Generally, a positive correlation was found between biofertilizers and fusilade on broad bean yield, so that to maximize broad bean productivity and reducing production costs as well as weed suppression, thus it is recommended for cultivating broad bean with dual inoculation (R. leguminosarum plus B. megaterium) asbiofertilizersand using fusilade at (1.0 L/fed.) with spray tank additives for a narrow weed control which increased productivity  of broad bean during the two years ranged from 324.01 to 349.27% (mineral oil) and with 296.06 and 340.32% (glue), respectively, and seed protein  than untreated control.
