In order to investigate the influence of spraying with proline and potassium humate (PH) on productivity and chemical components of Broad bean, cv. Koprosay, two field experiment were conducted at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate throughout 2016 and 2017 seasons. Randomized complete blocks design was used with three replications. Height of plant, No. of leaves/plant, total chlorophylls, leaves fresh and dry weight, length and wide of pod, green seeds number per pod, the weight of 100 green seeds, total yield, N, P, K and proline percentages in leaves N, P, K, total carbohydrates and crude protein percentages in green pods were estimated. Spraying broad bean plants with 2 L PH/fad in addition 100 mg proline/L produced the highest values of all estimated traits in both seasons. Accordingly, it could be suggested that spraying broad bean plants grown under saline soil with 2 L PH/fad and 100 mg proline/L to improve growth characters and yield in addition to chemical components of broad bean.
