| Abstract | ||
| Biostimulants are natural organic materials that have been shown to enhance plant growth and development when applied in small quantities. Where influence several metabolic processes such as photosynthesis, nucleic acid synthesis, ion uptake etc. The experiment was carried out in the laboratory of Agriculture Faculty, Derna University, Libya, using a Random Design (CRD) in 3 replicates, to study the effect of two concentrations of licorice roots extract, and dry yeast extract on the vegetative growth of faba bean. Faba bean seedlings were treated on 3 different times of interval 10 days, where the first treatment was carried out when the first leaf appeared,. The results of the variance analysis showed that there were significant differences between the treatments under study. Foliar applications were enhanced vegetative growth characteristics such as (plant height, number of leaves/plant, leaf area, fresh weight/shoot, as well as dry weight/shoot) during the three sampling stages (after 45 from planting, after 60 days from sowing, and 75 days after sowing). When yeast extract, and licorice extract were used at the second concentration (4 g/l), the plant height increased by 79.3%, and 86.6% compared to the control as the average of the three stages, respectively. Licorice extract 4 g/l produced a significant effect on the number of leaves/plant, fresh weight (g.), and dry weight (g) at a 5% level of significance, whereas was a significant difference in leaf area (cm2/plant), when used yeast extract (4g/l), compared with control (water treatment only). | ||
