4. Cultivation and Harvesting Process
Below is the standardized production process used by Central Highlands to ensure export-quality Japanese Sweet Potatoes.
Selection of Growing Areas
Before planting, suitable growing areas are carefully selected to ensure optimal soil quality, climate conditions, and water availability.
Japanese Sweet Potatoes grow best in loose, well-drained soils, such as light loam or sandy loam, with neutral pH levels. Regions with stable temperatures and moderate rainfall allow tubers to develop evenly, producing smooth skin and deep yellow flesh. All growing zones are centralized, pollution-free, and fully traceable.
VietGAP / GlobalGAP Farming Practices
Safe farming practices are strictly applied, including the use of disease-free planting material, controlled fertilization programs, and only approved plant protection products.
All farming activities are fully documented through cultivation records, ensuring traceability and compliance with food safety standards. Pre-harvest withdrawal periods are strictly observed to protect product quality.
Optimal Harvest Time for Export Quality
Japanese Sweet Potatoes are harvested after 5–7 months of growth, when tubers reach the ideal size range of 70–500g, with smooth skin, rich yellow flesh, balanced sweetness, and soft texture. Harvesting at the correct maturity stage minimizes mechanical damage, reduces post-harvest loss, and ensures longer shelf life for export.
