Two field experiments were conducted at Agric. Exp. Res.  Sta., Fac. Agric., Cairo Univ., during  2011/2012 and 2012/2013 seasons to study the effect of  five foliar application of micronutrients (F1: control "spraying water only, F₂: Fe+ Mn at 5 g L^-1 , F₃: Fe+Zn at 5g L^-1 , F₄: Mn+Zn at 5 g L^-1 and F5: Fe+Mn+Zn at 5 g L^-1) on yield and seed quality of three cultivars of faba bean (Giza 3, Sakha 1 and Giza 716). A spilt plot design in a randomized complete blocks arrangement with three replications was used. Micronutrients treatments were randomly assigned for main plots while, faba bean cultivars were randomly arranged for sub plots. Results showed that foliar application treatments significantly increased all yield traits and protein content compared with control treatment in both seasons. Spraying Fe+Mn+Zn mixture produced the greatest plant height (103.3 and 107.3 cm), number of branches plant^-1(3.46 and 3.60), number of pods plant^-1 (18.40 and 18.80),  pods weight plant^-1 (38.67 and 40.03 g) , number of seeds pod^-1 (3.39 and 3.42), 100-seed weight (65.53 and 65.77 g), seed yield plant ^-1(35.80 and 37.90 g), seed yield (1746 and 1786 kg/fed.), straw yield (4536 and 4618 kg/fed.) , biological yield (6283 and 6405 kg/fed.) , harvest index (27.97 and 28.55%) and protein content (27.97 and 28.55 %) in both seasons, respectively. Giza 3 cultivars was superior in yield traits and protein content followed by Sakha 1 cultivar. However, Giza 716 cultivar gave the lowest values of yield traits and protein content in both seasons.
