EFFECT OF FOLIAR FERTILIZERS SPRAY, BORON AND THEIR INTERACTION ON BROAD BEAN (VICIA FABA L.) YIELD

A factorial experiment was conducted to study the effect of six spray treatments of foliar fertilizer (neutral, high-phosphorus, high potassium, urea, extracts of seaweeds, in addition to control) with two levels of boron (spray and without spray) and its interaction on dry seeds yield of broad bean and some of its characteristics. The experiment was carried out in the farm Guidelines during the agricultural season 2012/2013 as factorial experiment according to complete randomized block design with three replications. The most important results of the experiment summarized as follows: all fertilizers treatments led to increase pod dry weight, number of seeds / pod, 100 seed weight, seeds yield/plant, seeds yield per unit area and protein in the seeds significantly compared to control treatment. Boron treatment led to increase all the traits significantly except (100 seeds weight) compared to control. The interaction between the factors had a significant effect on pod dry weight, number of seeds / pod, weight of 100 seeds, seed yield/plant and unit area and protein in seeds. The interaction of urea with boron was superior on all other interactions with a percentage increases of (51.84 %, 56.9 %, 30.8 %, 10.88 %, 10.89 %, 64.1 %), respectively, compared to control.
