Plant nutrition is one of the determinate factors in fruit production cycles. Foliar fertilizer application is considered a complimentary nutrition method which proofed to be highly efficient under certain conditions. In this research, a foliar application of balanced foliar fertilizer N.P.K (20:20:20) +TE with different concentrations (0, 5, 10, and 15 g/l) was conducted on Coscia pear seedlings. Plant vegetative growth traits in addition to certain biochemical characteristics (Roots and leaves dry weight percentages, chlorophyll content, carbohydrates content, and minerals content) were measured. The results showed that plant height, stem diameter, branches length, leaf area, main roots number, root length, root dry weight, leaves dry weight, chlorophyll, and minerals content were significantly increased by increasing foliar spray concentration from 5 to15 g/l which confirms the importance of foliar spray as an enhancer of plant physiological operations. However, the highest carbohydrate content and carbohydrate/nitrogen (C/N) ratio were observed under A10 (10 g/l) treatment which might refer to the importance of this level of foliar fertilization, specifically in this phase, to accelerate the transition from juvenility to production phase.
