The experiment was conducted in 2022 at the Department of Horticulture and Landscape Engineering, College of Agriculture, Tikrit University, to determine the impact of organic fertilizer and stimulants on the vegetative growth of pomegranate seedlings in their first year of permanent cultivation. The study treated seedlings with auxins IBA and NAA at 100 and 200 mg L -1 , glucose sugar at 5000 mg L -1 , and Commercial stimulation Taravert Evo at 6 and 12 ml seedling -1 . The experiment used a Randomized Complete Block Design (R.C.B.D) with two factorial elements. The experimental unit comprised one seedling, and Duncan’s multiple test at 5% was used to compare the averages. The treatment with organic fertilizer at 40% increased vegetative growth characteristics like leaf area, total leaf area, seedling height and diameter, and leaf chlorophyll content, while the stimuli increased them. It caused substantial changes in vegetative development (leaf area, total leaf area, and plant height). Stimuli treatment significantly altered vegetative development (leaf area, total leaf area, plant height, and chlorophyll content). The analyzed parameters’ interactions significantly affected vegetative features as leaf area, total leaf area, seedling diameter, and leaf chlorophyll content.
