Abstract

The study was conducted at a private nursery (Mohammed Nursery) located on the Erbil road during the 2022 agricultural season. The experiment was carried out on composite gardenia plants propagated by cuttings and grafted onto one-year-old rootstocks for a duration of 5 months from April 2022 to October 2022. The study aimed to investigate the effect of shading at two levels (0% and 75% direct sunlight, using a green net (Saran cover)), the addition of organic fertilizer (vermicompost) at two levels, and the application of iron fertilizer in the form of chelated iron at three levels (0, 0.1, and 0.2 g.L-1) on the leaf content of certain elements in gardenia plants. The shading effect at 75% resulted in a significant increase in leaf nitrogen content, reaching (1.72%) and iron content (73.94 mg.kg-1). The application of organic fertilizer at 25% also demonstrated a significant increase in leaf nitrogen content (1.75%), phosphorus (0.248%), potassium (1.36%), and iron (67.95 mg.kg-1). The use of chelated iron at a concentration of 0.2 g.L-1 showed a significant effect on most parameters, with the highest results in leaf nitrogen content (1.78%), phosphorus (0.256%), potassium (1.28%), and iron (78.45 mg.kg-1).
