Sweet potato (Ipomoea batatas.L), the third most important root crop globally, offers significant nutritional value and high yield potential., making it a critical crop for food security, particularly in developing regions. However, its production is influenced by various factors. As the global population grows and dietary demands shift toward more sustainable and nutritious food sources, there is an increasing need to enhance the productivity of sweet potato cultivation. This review provides a comprehensive overview of strategies to improve sweet potato yield, with a focus on practical agricultural approaches. Key aspects such as the selection of high-yield, disease-resistant varieties are emphasized. Soil management practices, including optimal soil conditions, preparation techniques, and nutrient management, are demonstrated. Planting techniques, including optimal timing, plant density, and propagation methods, are also highlighted. Effective irrigation and water management strategies for different growth stages are crucial and addressed in detail. Pest and disease management is addressed through integrated approaches, while weed control strategies emphasize sustainable practices. Nutrient management and fertilization are addressed, comparing organic and synthetic options. Finally, the review offers guidelines on harvesting handling to reduce losses and maximize yield. In summary, integrating genetic improvement with effective agricultural practices can significantly enhance sweet potato production. However, future research should prioritize developing new varieties with higher yield potential and greater tolerance, ultimately improving the marketability and economic viability of sweet potato farming.
