The application of some organic materials, Licorice extract, yeast extract alone or in combination with each other as foliar spraying and soil addition with different concentrations 10,15 and 20 g/L was studied on Red Globe grapevines seedlings. The experiment was conducted in the 2015 season and extended for two successive seasons, comprised eleven treatments to improve the quality of grafted seedlings. Results indicated that soil addition in two concentrations 20 g/L and 15 g/L of a mixer of Licorice extract and yeast respectively were the most effective in stimulating all growth characters with a significant effect on leaf area, number of leaves, leaf content of N %, shoot length and diameter and root length and number, followed by the foliar spaying treatments which induced significant increments in all parameters compared to the control.
