In Sub-Saharan Africa, sweetpotato pre-basic seed is multiplied in screenhouses using a sterilized soil substrate. This is expensive and unsustainable. The use of sand substrate with a fertigation system (“sandponics”), is an alternative. The study compared the cost-effectiveness for pre-basic se...

Sweetpotato (Ipomoea batatas L.(LAM)) is one of the most important food crops in developing countries, including South Africa. Most sweetpotato varieties in South Africa are cream or white fleshed and lack the essential beta-carotene of the orange-fleshed varieties. To develop new varieties with ...

Sweetpotato is used in various food preparations in place of rice, cassava, yam and plantain in Ghana. In spite of this it does not have the same importance in Ghanaian diet as other root and tuber crops. Consumer taste, preference and acceptance are critical in determining the suitability of swe...

Fried chips prepared from cassava tuber or flour are consumed as snack in some Asian countries such as India, Indonesia, Malaysia and the Philippines. Chips made from fresh tubers were similar to potato chips and contained safe levels of cyanide, if low-cyanide varieties were used. Those proces...
