An integrated approach to sweetpotato production research that incorporates the fundamental basis of storage root formation as key to the development of better management practices. Current areas of investigation include:

• Development of model-based decision support tools for optimum storage root production under various agroclimatic conditions.
• Integration of sensor-derived information in management decision making.
• Increased production efficiency through a storage root phenology-based optimization of irrigation, nutrient, and tillage inputs.
• Understanding root architecture and storage root development responses to low nutrient, drought, and flooding conditions.
• Evaluation of preharvest cultural practices that contribute to improved storability.
