Two field experiments were carried out to evaluate shedding (%), yield, and its components of three faba bean cultivars (Nubaria 4, Nubaria 5, and Giza 716) under growth-promoting treatments (potassium as a foliar and soil application, yeast extract, algae extract, and molasses) in the 2022/23 and 2023/24 seasons. The results showed that shedding %, number of flowers, total chlorophyll content, yield, and yield components were meaningfully augmented by applying molasses and potassium (K) as foliar treatment compared to the control in both seasons, except for straw yield (kg fed^-1) and shedding %. The cultivars were meaningfully varied for all studied characters, where Giza 716 was the best cultivar for all vegetative characters and yield components as compared to the other cultivars under study, while Nubaria 4 recorded the highest shedding %. Furthermore, the interaction between K treatments, natural extracts, and faba bean cultivars led to significant increases in yield components in both seasons. In general, applying molasses and foliar treatment with potassium was the best treatment for the maximum yield of faba bean plants (Giza 716 cultivar).
