The results showed a significant effect of nitrogen fertilization on all the growth parameters studied. The rate of 120 kg/ha achieved a significant difference from the rest of the treatments, giving the best results in terms of plant height (27.50 cm), number of leaves on the plant (15.10 leaves), and leaf surface area of the plant. (725.50 cm2), fresh weight (77.50 g), and dry weight of leaves (9.10 g).
Keywords: spinach, Spinacia oleracea L., nitrogen fertilization, vegetative growth standards.
