The experiment was conducted in one of the laboratories of the Plant Science Department, University of Derna, from February 4, 2023, to March 4, 2023, to test the effect of dry yeast solution on the vegetative and root growth of broad bean (Vicia faba). Plants were treated 16 days after planting with a 2% yeast solution through foliar spraying three times, with 4 days between each application. The study results showed a difference in the growth indicators studied and the chlorophyll content of the leaves compared to untreated plants. The highest results for shoot length and root length were 25.5 cm and 15 cm, respectively, with yeast treatment compared to untreated plants. Regarding wet and dry weight, results indicated a positive effect of the yeast solution, showing differences in wet and dry weights of shoots and roots compared to untreated plants, with the highest results being 12.5 cm and 2.76 cm for wet weight of shoots and roots, respectively, and 1.84 cm and 0.95 cm for dry weight of shoots and roots, respectively, compared to untreated plants. Additionally, chlorophyll content in leaves treated with the yeast solution showed the highest result of 3.2 at a wavelength of 663 nm compared to untreated plants. A positive effect of the yeast solution on leaf area was also observed, with results of 8.11 cm² per plant compared to 5.27 cm² per plant for untreated plants.
