One of this week’s Farmer stories is about a Zambian couple growing and selling orange-fleshed sweet potato (OFSP) vines and roots. OFSP is a popular crop because it is relatively easy to grow, tolerates dry spells and poor soil, and is accessible to many small-scale farmers, including women, because it does not require significant capital. When harvested, the potatoes can be transformed into many nutritious foods.

Radio broadcasters working on programs about OFSP or other kinds of sweet potato may want to include additional information about production, harvesting, and consumption.
This guide from the International Potato Center is full of detailed information about growing and using sweet potatoes. It was written as a training manual for extension officers and farmers’ organizations and, as such, it provides clear explanations and illustrations on a variety of topics, including:

  • Characteristics of different sweet potato varieties.
  • Sweet potato seed systems.
  • Land preparation, planting methods, and intercropping.
  • Disease management.
  • Harvest and post-harvest practices.
  • Nutritional content and consumption of sweet potato.

The guide includes several volumes, and is available in English, French, and Swahili, at the following link:
