The current experiment was conducted during the winter season of 2020/2021 in one of the fields belongs to Horticulture and landscape Engineering Department / College of Agriculture / University of Qadisiyah in order to find out the effect of spraying high phosphorus solution and potassium sulfate on growth and yield of Vicia faba cv. local. The experiment included nine factorial treatments: the interaction between spraying with an activator solution contains high phosphorus at concentrations of 0, 1 and 2 g. L-1 and spraying with potassium sulfate at concentrations of 0, 1 and 2 g L -1 also and their interaction in a complete random block design with three replicates. Results showed that spraying with high phosphorus solution at their two concentrations increased all parameters studied especially at a concentration of 2 g.L-1 such as plant eight, number of branches, chlorophyll content, number of pods, pod weight, seed weight and plant yield which recorded values of 88.00 cm, 4.48 branches, 43.78 Spad, 14.50, 19.79 g, 3.83 g and 286.95 g, respectively. Same results were found for potassium sulfate, where the highest concentration gave the highest values except the number of pods which did not differ from the control treatment, and the weight of the pod, where the two concentrations were not differ significantly from each other although they exceeded the control treatment in their effect. With regard to the interaction between the two factors, the combination of the higher concentration of both substances was superior in giving the highest values of the parameters studied except for the number of pods which recorded the highest value at the combination treatment of 1 g. L-1 of phosphorus and 0 g. L-1 of potassium.
