The study was conducted at the Al-Hindiya Gardening Station (Karbala province), To study the effect of spraying 3 levels of nano zinc (0, 2, 4 g.L−1) and two levels of humic acid solution (2, 4 ml.L−1) and adding urea mineral fertilizer at two levels (5, 10 g.seedlings −1) in the growth of pear seedlings, Hollywood cultivar grafted on apricot seedlings. The experiment was conducted according to completely randomized designs with three replicates, and the results were as follows: The treatment of zinc at a concentration of (2 ml.L−1) was significantly higher in all vegetative growth traits that included seedlings length, stem diameter, number of leaves, leaf area, dry material of the plant and leaf content of chlorophyll and zinc and gave the highest averages of 84.20 cm, 7.62 mm, 40.70 leaf.seedling−1, 23.67 2 cm2, 42.28 g, 30.27 spad, 9.71 mg.100 g−1, respectively, by comparison treatment, Where, the treatment with a humic acid concentration of 4 ml. Liters -1 was excelled on the above traits and gave the highest averages amounted to 78.17 cm, 7.04 mm, 41.73 leaf.seedling−1, 23.64 cm 2, 43.53 g, 29.17 spad, 9.34 mg.100 g−1 in respectively compared to the treatment of 2 ml.L−1, the treatment of adding urea mineral fertilizer at the level of (10 gm.seedling−1) was significantly excelled by giving the highest values of all studied vegetative traits amounted to 77.89 cm, 7.18 mm, 39.87 leaf.seedling−1, 22.45 cm 2, 42.19 g, 28.64 spad, 9.39 mg. 100 g −1 respectively Keywords: term, term, term
