OFSP Orange-Fleshed Sweet Potato (High provitamin A)

Orange Sweetness, Nutrient Richness, and Farmer's Success - Embrace OFSP!

The Orange Fleshed Sweet Potato (OFSP) is a biofortified crop that contains high levels of beta-carotene. Sweet potato cultivars with orange flesh have more beta-carotene than those with light-colored flesh cultivars. After eating OFSP, the beta-carotene is converted into vitamin A, providing essential nutrition and supplementing the diet of people. It has huge potential to improve food and nutritional security across Africa.

Problem

  • Vitamin A Deficiency:  Widespread vitamin A deficiency contributes to malnourishment, affecting the health and well-being of communities, especially children and pregnant women.
  • Insufficient Tuber Yields: Traditional sweet potato varieties yield only 3-7 tons per hectare, resulting in limited food availability and income for farmers.
  • Limited Nutrient Sources: The lack of diverse and nutrient-rich crops hampers overall nutrition, posing a challenge to addressing dietary deficiencies and promoting sustainable agriculture.

Solution

  • Beta-Carotene Enrichment:  OFSP, with its high beta-carotene content, addresses vitamin A deficiency by providing a rich source of this essential nutrient, promoting better health and nutrition.
  • Improved Varieties and High Yields: OFSP's improved varieties yield 25 tons per hectare, significantly surpassing traditional varieties, thereby enhancing food security and increasing farmers' income.
  • Versatile and Nutrient-Rich Crop: OFSP offers a versatile and nutrient-rich crop, diversifying nutrient sources and contributing to overall nutrition, promoting a sustainable and healthier agricultural ecosystem.

Key points to design your business plan

For Seed Multiplier :

Production of this technology enhances nutrition, offers essential nutrients, and improves food security in Africa. It empowers diverse farming communities, contributing to enhanced health and wellbeing on a global scale.

In order to multiply efficiently the variety:

  • Acquire enhanced OFSP varieties,

  • Participate in training sessions on propagating healthy planting materials and managing crops.

Your potential customers are : wholesale distributors of seed to retailers, and to development projects, government agencies, and NGOs. 

Building strong partnerships with wholesale distributor networks is key to the success of your business.

 

For Users

Using this technology  offers essential nutrients, and improves food security. It not only benefits human nutrition but also adds value to producers' endeavors by extending to animal feed.

As key partners you need vine multipliers.

You need to estimate the profit realized with the use of the product, knowing that 10 kilogram of OFSP vines are usually sold for less than USD20.

  1. Obtain Planting Material:

    • Purchase a 10kg bag of OFSP vines, usually available for less than USD 20, including transport costs.
  2. Planting:

    • Space the vines 50cm apart in rows, maintaining a 30cm distance from plant to plant.
  3. Propagation:

    • Use healthy slips or cuttings obtained from the vines. Plant the slips at an angle in the soil.
  4. Region:

    • OFSP is adaptable to all agroecologies in Africa, making it suitable for various climates and regions.
  5. Application:

    • OFSP tubers can be consumed after cooking. Alternatively, they can be milled into flour or mashed into puree for a range of products such as bread, chapatis, cakes, juices, and porridge.
  6. Livestock Feed:

    • Peels and tubers can be used to create feed meal for animal rearing, enhancing protein content. Leftover vines and low-grade tubers can be turned into silage, providing nutritious fodder for ruminant livestock and pigs.
  7. Propagation Method:

    • OFSP can be propagated from seeds, tubers, or vines. Cuttings from vines are commonly used for planting and are easy to prepare.
  8. Planting Technique:

    • Plant healthy slips or cuttings by inserting them at an angle in the soil, with a spacing of 50cm between rows and 30cm from plant to plant.
  9. Availability:

    • Improved OFSP varieties are available in Ethiopia, Kenya, Malawi, Nigeria, Uganda, and Zambia, and are ready to be scaled for addressing malnutrition and increasing profits for producers.
