Abstract:
Two field experiments were carried out at Etay El-Baroud Agricultural Research Station, El-Behera Governorate during 2009/2010 and 2010/2011 seasons to study the effects of foliar application with micronutrients on yield and yield components of faba bean (c.v. Misr 1). A randomized complete blocks design with 3 replications was used. Results showed that, spraying with Fe+Zn+Mn increased yield and yield components, while, the highest no. of branches/plant were found with Fe+Zn, 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, Alternaria leaf spot incidence on treated plants significantly decreased 18.2-60.5% compared with non-treated control plants. The results concluded that, spraying Fe, Zn and Mn alone or combination could be recommend to control leaf spots and to enhance yield and quality of faba bean under the environmental conditions.
