Abstract
Two field experiments were carried out at private farm at El-Gammalia district, Dakahlia Governorate, Egypt;  during summer seasons of 2013 and 2014  to study the effect of some foliar substances, i.e., yeast extract at 20 m/L, proline at 100 ppm, silicon at 200 ppm, ascorbic acid at 250 ppm, salicylic acid at 250 ppm and selenium at 50 ppm on vegetative growth, flowering, fruit yield and its components and quality of eggplant (solanum melongena L.) cv. Black beauty.
The results show that foliar applications gave the highest number of leaves and branches,   plant height, fresh and dry weight, leaf area, and stem diameter were obtained in both seasons. Also, treatments resulted the highest in number of flower/plant, number of days to first flowers and the lowest in fruit setting compared with the control in both seasons. Moreover, treatments were the highest in total soluble solids (TSS) and vitamin C (mg/100g fw)  and the lowest in titrable acidity (%) in both seasons. Also, treatments were the highest in N, P and K of leaves and N, P, K, Fe, (No2 + No3) and protein in both seasons.    All foliar applications significantly increased yield characters compared to the control treatment. The superior application was proline followed by yeast extract and silicon in both seasons, respectively.
