Effect of Intercropping and Phosphorus Fertilizer Treatments on Incidence of Rhizoctonia Root-Rot Disease of Faba Bean

Abstract

In greenhouse and field experiments, conducted in two successive winter seasons 2012/2013& 2013/2014 the effect of intercropping three cultivars of fababean (Giza3 Mohassan & Giza 40 and Sakha1) with wheat (Sakha 93). As well as the effect of phosphorus fertilizer treatments on incidence of root rot of three cultivars faba bean, as well as yield component three cultivars faba bean, as well as yield component was studied. Application of phosphorus fertilizer (100 and 200 Kg/fed) as superphosphate (15.5 % P2O5) before planting caused a reduction in incidence and disease severity on plants of the three cultivars of faba bean in greenhouse and field experiments. In field experiments, were intercropping and phosphorus fertilization at (100 and 200 Kg/fed) respectively, which reduced the root-rot diseases. Intercropping three cultivars of faba bean (Giza 3 Mohassan Giza 40 and Sakha 1) with wheat Sakha93 and phosphorus fertilizer significantly increased yield characters i.e., plant height, number of branches, number of pods plant, 100 seeds/weight and seed weight ardad/fed.
