N2  - To evaluate the effects of the individual foliar application with gibberellic acid (GA₃) or with the natural extracts; Yeast, Moringa and Aloe and the combination between them, the morphological characters, chemical composition and the anatomical structure of leaves of Ficus benjamina cv. Exotica plants were recorded. The results revealed that treating F. benjamina cv. Exotica plant separately either with GA  at 200 ppm or with yeast extract at 8g/l gave the highest significant values of plant height, number of leaves/plant, root length and the fresh weight of leaves, stem and root, in both seasons. The exception was in the number of branches/plant, as it was increased with GA₃ at 150 ppm and the same dose of yeast extract. The lowest values of the above mentioned characters were noticed either separately with GA3 at 50 ppm or with Aloe extract at 100 ml/l. The combination between GA₃ at 200 ppm and yeast extract at 8g/l gave the highest significant values of all the morphological characters and the anatomical structures. While treated the plants with GA₃ at 50 ppm combined with Aloe extract at 100 ml/l gave the lowest values of plant height, number of leaves/plant and the fresh weight of leaves, stem and root. The highest significant values of; phytosynthetic pigments (chlorophyll a, b and carotenoids), total carbohydrate content, protein content, total phenols, N., P., K. and copper contents were recorded in the plants sprayed individually with GA₃ at 200 ppm or with yeast extract at 8 g/l or the combination between them
