The story of Orange-Fleshed Sweetpotato (OFSP) and its role in combating
vitamin A deficiency (VAD) and malnutrition has been well told in agricultural
and nutrition circles. In those stories, the most common stumbling block is
obtaining consumer acceptance of the orange variety over its white fleshed
relative. This has not been the case in Uganda, where OFSP has long been
appreciated by consumers and is widely available in markets throughout the
country.
This equatorial country has abundant rainfall most of the year and plants
benefit from long sunny days. “Almost everything planted in Uganda grows,”
laughs Robert Mwanga, CIP sweetpotato breeder known widely for his release of
prominent OFSP varieties over the last 30 years.
Mwanga is right. Uganda’s rainfall, sun, and rich soil make it one of the
few countries where all crops of the CGIAR Research Program on Roots, Tubers,
and Bananas (RTB), which CIP serves as the lead center, thrive. Cassava,
sweetpotato, and cooking bananas are regularly on Ugandan tables.
In the Mukono district 40 kilometers from Kampala, Nalougo Sekiguce, opens
the door to her screenhouse where she grows three varieties of OFSP. Nalougo
leads one of four farmers groups in the district that CIP and extension partner
Vedco provide with clean planting materials and extension services. Before
entering the screenhouse, Nalougo instructs us how to clean our shoes. Once
inside, she shows us the varieties that she grows. She is a vine multiplier who
raises sweetpotatoes that are virus-free and then sells the vines to neighbors
who grow these improved varieties in kitchen gardens and to sell.
Word has gotten out about Nalougo’s vines. The yields they produce far outstrip other varieties planted and her neighbors demand only the vines that come directly from her screenhouse, which protects them from pests and diseases. She has been a model farmer over the years and she now participates in field trials of new CIP varieties.

At a meeting of several farmer groups from Mukono in the St. Judes Primary
School, farmers discuss their successes and challenges in growing sweetpotato.
Nalougo’s success in selling vines inspires others to want to do the same. The
demand for vines by neighbors and others is high. A program on Farm Radio
broadcasted Nalougo’s cell phone number and she was soon swamped with orders
that nearly emptied her screenhouse. Others in the meeting worry about drought
and the signs of sweetpotato virus disease that they have noticed on some
vines. Some still wonder how much more success they could have if they had more
tools or more screenhouses. Nalougo herself wonders out loud how she could
export sweetpotato to other regions or countries just as they see apples in
their markets imported from other countries in Africa.
The meeting in the schoolhouse ends with dancing and singing. The song they
sing with the most enthusiasm is about OFSP and the health benefits it
provides. “The orange sweetpotato is the healthy one,” the song goes. “It’s
good for the eyes and the body.” They sing because they hope others will take
up OFSP but more because they believe in it.
