Sustainable Cultivation of Dragon Fruit: Integrated Nutrient and Pest Management Strategies for Enhanced Productivity and Environmental Stewardship

Dragon fruit (Hylocereus spp.), an increasingly popular tropical fruit, has attracted global interest because of its distinct appearance, nutritional value, and health advantages. As cultivation has spread from its native Central and South American regions to tropical and subtropical regions around the world, there is an increasing demand for sustainable production approaches to address environmental, economic, and social issues. This study provides current knowledge on three different types of dragon fruits—H. megalanthus, H. undatus, and H. costaricencis—and their biology, agronomic requirements, and worldwide production trends, highlighting the critical need for management solutions. Conventional practices, which frequently rely on chemical fertilizers and pesticides, are compared with new sustainable approaches such as organic amendments, high tunnel systems, and agroforestry. This review examines regional challenges like climate variability, pest and disease issues, and pollination limits and explores innovative solutions to boost production and resilience. Socioeconomic factors, including market trends, farmer education, and policy frameworks, are recognized as key influences on the adoption of sustainable practices. This article highlights important research gaps, including the need for genetic improvement, digital agriculture tools, and strong certification mechanisms. This review integrates diverse views and provides actionable ideas for researchers, policymakers, and practitioners seeking to increase productivity, environmental stewardship, and long-term sustainability in dragon fruit agriculture.
