Abstract
The global market for flowers and ornamental plants is expected to expand at a rate of approximately 6.3% over the next five years, reaching an estimated value of $57.4 billion USD by 2024. Tuberose (Polianthes tuberosa L.), a summer flower cultivated by small-scale growers primarily for export. The study was aimed to cultivate tuberose plants in Al-Jabal Al-Khader region, introducing them as a new cut flower crop, as a source for tuberose, and leveraging their economic potential. A field experiment was conducted over two summer growing seasons to investigate the impact of different levels of compound fertilizer (nitrogen, phosphorus and potassium, NPK 4:4:4) in application rates (0, 500, 1000, and 1500 kg.ha-1) and foliar sprays of micronutrients iron (Fe), zinc (Zn), manganese (Mn), and a )mixture of these three elements) on tuberose bulbs. The experimental design was a completely randomized block design split-plot with three replications. The NPK fertilizer levels were randomly assigned to the main plots, while the micronutrient treatments were allocated to the subplots. The study found that varying rates of NPK fertilization did not significantly affect the number of bulbs per plant over the two growing seasons. In contrast, the application of micronutrient foliar sprays had a notable impact, with the mixture of Fe, Zn, and Mn yielding the highest significant increase in bulb number per plant in both seasons. It is recommended to apply a mixture of the three micronutrients (Fe, Zn, and Mn) as fertilizer to produce high-quality Tuberose plants for various decorative purposes in landscaping.
