| Abstract: The research was conducted in a greenhouse at the Department of Horticulture and Garden Engineering, College of Agriculture, University of Anbar, Ramadi City, to study the impact of NPK supplementation and CPPU cytokinin spraying on Ficus nitida L.'s vegetative and root growth properties. The study encompassed two primary factors. The first factor comprises the NPK chemical fertilizer in four distinct concentrations: F0 (no addition), F1 (1g urea, 3g DAB, 2g potassium sulfate), F2 (2g urea, 6g DAB, 4g potassium sulfate), and F3 (3g urea, 9g DAB, 4g potassium sulfate). The second factor involves the cytokine CPPU at three concentrations: C0 (no addition), C1 (3 mg/ liters), and C2 (6 mg/ liter). The study was structured using a randomized complete block design (RCBD) comprising three blocks, with three pots allocated per experimental unit. Each block consisted of 36 coefficients, resulting in a total of 108 experimental units across all blocks. Leaf area ,the number of leaves per plant, The increase in the number of branches, the percentage of nitrogen ,phosphorus ,and potassium in the leaves, the percentage of carbohydrates ,And the surface area of the roots 30.837cm2 , 185.083 leaf plant-1 , 40.500 Plant Branch-1 , 2.66% , 0.291% , 1.585% , 6.005%,43.041 cm-1. The increase in vegetative, root, and chemical growth characteristics is attributed to the fact that chemical fertilization with nitrogen plays a major role in the plant's life by participating in the formation of RNA and DNA acids, as well as the enzymatic co-factors NAD and NADP, and also participates in the photosynthetic process (El-Badawy and Sultan, 2020). | ||
