The experiments were conducted under sandy soil conditions in the experimental farm of the National Research Center in Nubaria region. The objective of the experiments was to investigate the physiological responses, growth and yield of eggplant to the foliar application of putrescine, yeast and vitamin C under such sandy soil conditions. Vegetative growth measurements, yield, hormonal changes in leaves (Cytokinins) and N, P and K contents of leaves were recorded to study the effects of these treatments. Foliar application of putrescine, yeast and vitamin C resulted in a significant increment of vegetative growth (including plant height, number of leaves, number of branches and fresh weight of plants) and yield of eggplant compared to control plants. Yeast treatments had the best results concerning plant growth and yield. All treatments increased cytokinins content especially at the high level of yeast. The treatments resulted in a significant increase of N, P and K contents of leaves. The possible roles of the treatments on growth, yield and physiological responses of eggplant are discussed.
