Abstract
The study was conducted in the Department of Horticulture and Landscaping/ College of Agriculture/ University of Anbar during the growing season 2021-2022 in the greenhouse to study the effect of shading, iron and sulfur on Gardenia seedlings planted in pots with a diameter of 35 cm. With three replications, the averages were compared with the L.S.D. test at a probability level of 5%. The results showed that the gardenia plant responds to shading and fertilization with iron and sulfur, and the interaction treatment showed a high significant increase and gave the highest rate in the number of flower buds, the number of petals, the diameter of the flowers and the weight of the flowers amounted to 40,440 flower buds plant-1, 25,883 petal flower-1, 88.185 mm and 23.667 gm sequentially, in addition to recording the highest average leaf content of total chlorophyll amounted to 41,400 mg/100 g tissue and the highest rate of total leaf area amounting to 9437.463 cm2 plant-1. The interaction treatment (S1F3) significantly outperformed the rest of the treatments in iron and sulfur content of leaves by giving it the highest The average iron content was 119.417 mg kg-1 dry matter, and the highest sulfur content of leaves was 195,000 mg kg-1 dry matter.
