Since ancient, many edible crops have been planted in Egyptian lands that had become an essential part of daily eating habits; faba bean (Vicia faba L.)became one of these crops and also became the most important food legume crop in Egypt. This experiment was carried out inthe two winter seasons (2020/2021 and 2021/2022) at Tag El-Ezz Research Station using two varieties of faba bean (Giza 843 and Nubaria 5) with adding sorbitol (sugar alcohol) and boron, individual or combined via soaking and foliar application to investigate the ability of improving seed yield and quality. Split plot design was used where, faba bean varieties were in main plots, while sorbitol and boron treatments were in sub-plots. Results indicated that the Giza 843 variety was better. Pronouncedly, differences among studied treatments either combination or single. Best performance was recorded with soaked Giza 843 variety with treatments (sorbitol at 10.0 g L-1 and boron at 10.0 mg L-1) and simultaneously foliar application with same rates during plant life. Generally, it can be concluded that the seed soaking and foliar application of sorbitol and boron was a successful way to improve field emergence and optimizing seed yield (quality and quantity) of both faba bean (Vicia faba L.) varieties Giza 843 and Nubaria 5.
