2022/2023) at the Experimental Farm of the Department of Agricultural Research and the Experimental Center of the Faculty of Agriculture, Benha University, Egypt to study the effect of foliar spray with seaweed extract and mineral fertilization treatments, i.e., The recommended from N P K (control),75 % of the recommended from N P K + Foliar spray of seaweed extract at 3 mg/L. , 50 % of the recommended from N P K + Foliar spray of seaweed extract at 3 mg/L. and Foliar spray of seaweed extract at 3 mg/L. on vegetative growth, yield, and yield components of Faba bean. The experiment was laid out in a Randomized Complete Block Design with three replicates. Faba bean plants treated with 75 % of the recommended from N P K + Foliar spray of seaweed extract at 3 mg/L. significantly gave the maximum Chlorophyll content, plant height, number of branches, Plant weight, Pod length, Weight of pods, Seed yield/plant, Harvest index, Weight of 100-seed, Biological yield/fed, Seed yield/fed, Seed nitrogen content, Seed protein yield, Seed phosphorus content and Seed potassium content and reduced Abscission in the flowers in both seasons. Based on the previous results, it could be concluded that growing promising Faba bean seeds (Giza 716 variety) treated by 75 % of the recommended amount from N P K + Foliar spray of seaweed extract at 3 mg/L treatment produced the maximum seed yield and its related traits
