Improved varieties have agronomic advantages over local varieties,but not much attention has been given to understand the nutritional content of the improved cowpea varieties released in Swaziland. This study investigated the physical and nutritional properties of improved cowpea varieties released in Swaziland. Five improved varieties (IT-04K-321-2, IT-97K-390-2, IT-18, IT-16, and IT-99K-494-6) and one local variety (Mtilane, as check) were analyzed for physical and chemical properties.

- The study examined how vegetable type, size, and drying load impact the dehydration rates and quality of solar-dried carrots, sweet potatoes, and collard greens.
- Significant differences were found in dehydration rates and beta-carotene content based on vegetable type, while vegetable dimensions influenced water activity.
- The best dehydration results for carrots and collard greens showed specific dimensions and drying loads yielded the highest beta-carotene and vitamin A activity, highlighting some loss in nutrient content during the drying process.
