To study the effects of foliar application with micronutrients on yield and yield components of faba bean (c.v. Misr 1), an experimental research was conducted in  complete randomized block design by three replications during the two growing seasons of 2009/2010 and 2010/2011 in Etay El-Baroud Agricultural Research Station, El-Behera Governorate. Results shwoed that, spraying with Fe+Zn+Mn increased plant height, number of pods/plant, number of seeds/pod, number of seeds/plant, 100 seed weight and seed yield /faddan in the combined data.
Also, chemical constituent, chlorophyll A, chlorophyll B, reducing sugars and the non  reducing sugars significantly increased in all treatments spray with micronutrients compared with non-treated (control).
Meanwhile, Altermaria leaf spot incidence on treated plants significantly decreased 18.2% - 60.5% compared with non-treated control plants.
