| Abstract | ||||
| Under field conditions, in the two successive seasons of 2010/11 and 2011/12 the effect of plant spraying with commercial chelated iron, manganese and zinc on severity of chocolate leaf spot and rust of faba bean cv. Misr 1 was studied. The effects on leaves chlorophyll content and some agronomic characters of the faba bean were also investigated. Severity of Botrytis fabae was significantly decreased on the treated plants and reduced the disease incidence between 7.93% to 36.9% compared with control .Also, microelements decreased rust disease severity between 15.4% to 62.8% in the two growing seasons, respectively . Chlorophyll (a) and (b) in leaves significant increased in all plants sprayed with micronutrients. Also, results showed that spraying faba bean plants with Fe, Zn and Mn alone or in combination increased plant height, number of pods / plant, 100 seed weight and seed yield / feddan . | ||||
