A field experiment was carried out in one of the fields designated for the Department of Field Crops, College of Agriculture, University of Karbala for the spring season 2019-2020 in a soil with a silty loam to study the effect of Boron spraying on growth and yield of bean. The experiment included studying two factors. First factor included boron concentration (0, 100 and 200) mg L-1. Second factor using three cultivars of bean (local, Dutch and Spanish). The experiment was designed as RCBD. The result showed the concentrations of boron was significantly increased in Average weight rate 50 seed (g), Average pods weight (g plant-1), Average yield seeds(g.plant-1) and the average yield biological (g.plant-1). Also affected varieties beans significant effect on the chlorophyll content (%) in leaves, Average weight rate 50 seed (g), Average pods weight (g.plant-1). As shown the interaction between the concentrations of boron and varieties beans was significantly increased Chlorophyll content (%) in leaves, Average weight rate 50 seed (g), Average pods weight (g.plant-1), Average yield seeds (g.plant-1) and the average yield biological (g.plant-1).
