Two field experiments were conducted on the eggplant crop Long Beryl, at the experimental farm of the Horticulture Department, Faculty of Agriculture - Omar Al-Mukhtar University, Al-Jabal Al-Akhdar, with the aim of studying the main effects of fertilization with different levels of nitrogen fertilizer and organic fertilizer, on all fruit crops and their components. Gradual increases in the added levels of nitrogen up to 450 kg/ha led to significant increases in the total and early fruit yield, plant productivity of fruits by weight and number, fruit length and diameter and fresh weight, in addition to increasing the efficiency of plants using nitrogen in fruit production. The gradual increase in the added rate of poultry manure was accompanied by gradual increases in both the total and early fruit yield, and plant productivity of fruits by weight and number, fruit length and diameter and their fresh and dry color. Fertilization at a rate of 450 kg nitrogen accompanied by fertilization Organic fertilizer at a rate of 20 tons/ha, led to a significant increase in both the total and early fruit yield, the number and weight of fruits/plant, the efficiency of plant use of nitrogen, in addition to the length, diameter, and fresh and dry weight of the fruit.
