ABSTRACT: The application of mineral fertilizers plays an important role in improving plant growth and development, particularly in ornamental palm species cultivated in nurseries and landscape systems. This study evaluated the effects of nitrogen (N), phosphorus (P), and potassium (K) fertilizers on the seedling growth of four ornamental palm species: Trachycarpus fortunei, Trachycarpus wagnerianus, Washingtonia robusta, and Jubaea chilensis. The experiment was conducted under controlled conditions using different mineral fertilizer treatments, and seedling height was measured periodically over several months to assess growth responses. The results demonstrated species-specific differences in nutrient requirements. Phosphorus fertilization significantly enhanced the growth of Trachycarpus fortunei, Trachycarpus wagnerianus, and Jubaea chilensis, indicating a higher demand for phosphorus during early developmental stages. In contrast, Washingtonia robusta seedlings exhibited a stronger response to nitrogen fertilization, suggesting greater nitrogen requirements for optimal vegetative growth. These findings highlight the importance of species-specific fertilization strategies for ornamental palm cultivation. The results provide practical recommendations for improving nursery production and landscape establishment of palm seedlings through optimized mineral fertilizer management.
