Field experiment was conducted in the vegetable field / Department of Horticulture and Land scape / College of Agriculture and Forestry / University of Mosul__during 2019-2020 agricultural season to study the effect of two factors. First: Spraying with zinc sulfate at a concentration of 300 mg. L −1 and without spraying (control). Second factor: Four levels of chemical fertilizer N 15 P 15 K 15 (0, 150, 300 and 450) kg. ha −1 on broccoli plants Hot Bro variety. The experiment conducted in a Split – plot system arranged in Randomized Complete Block Design (RCBD).Main plots included fertilization levels while sub plots included zinc spraying treatments. The results can be summarized as follows: The zinc spraying and level 450 kg. ha −1 fertilization kg. ha −1 was significantly superior in the plant height, number of leaves per plant, leaf area, circumference and weight of head, number of lateral heads, plant yield and total yield of heads, as compared to control treatment. The interaction between 450 kg. ha −1 of NPK chemical fertilizer and zinc spraying was superior in all above studied traits.
