An experiment was carried out  variation the efficiency of yeast extract at 1, 2 or 3 g/L and amino acids at 1, 2 or 3 cm³/L as a foliar application for each to improve vegetative growth and some of chemical content of pot moringa plants (two species) Moringa oleifera, and Moringa ovalifolia. Amino acids at 3 cm³/L was more effective than most of the other treatments for increasing plant height, leaf numbers, fresh and dry weights of plants, total chlorophyll and carotene of leaves and some  chemical composition. Amino acids at 3cm³/L as three foliar sprays at thirty days intervals improved vegetative growth and chemical content of moringa plants.
