What is the Difference Between Sweet Potatoes and Yams
What is the Difference Between Sweet Potatoes and Yams
The mix-up between yams and sweet potatoes began in the United States when
firm varieties of sweet potatoes were grown by African slaves before soft
varieties. They called the soft sweet potatoes yams because they resembled the
yams in Africa. Therefore, soft sweet potatoes were referred to as yams to
distinguish them from the new firm varieties.
Sweet potato varieties are classified as either firm or soft. The skin color
can range from white to yellow, red, purple or brown. The flesh also ranges in
color from white to yellow, orange, or orange-red. Currently, sweet potatoes
are the 3rd most important crop in seven eastern and central African
countries, and fourth in six southern African countries.
Yams are native to Africa and Asia. The sweet potato, maybe native to tropical
America introduced to Western Africa by the Portuguese in the 1500s. The sweet
potato is its 3rd most important agricultural product in terms of volume after
the plantain and the cassava. Uganda leads the way in the production of sweet
potatoes representing half the African supply followed by Nigeria and
Tanzania.

| Home Grown Yams |
The yam belt of West Africa includes Nigeria, Ghana, Benin, Cรดte d'Ivoire,
Central Africa, Cameroon and Togo, Nigeria alone produces 71 percent of the
yams. Yams are second to cassava as the most important tropical root crop
and are a staple food in many parts of Africa, Southeast Asia, and the South
Pacific. Seventy percent of the 50 million tons world output of 2008 was
grown in Nigeria.
The starchy tuber, with rough brown skin, is produced by an annual vine and
takes from 8 to 11 months to mature after planting. Yams are mainly grown
for cooking and eating. The tubers can be stored for up to six months
without refrigeration. Yams are second to cassava as the most important
tropical root crop.
Yams are one of the most common and popular root crops in tropical and
semi-tropical regions of Africa and have become a mainstay of many African
cultures. Besides their importance as a food source, yams also play a
significant role in the social and cultural lives of Africans.
The celebrated New Yam Festival in West Africa is an anticipated event each
year and a practice that has extended to overseas where there is a
significant population of Igbo tribes. Considered a prestigious crop, it is
the crop of choice for traditional feasts, gifts and fulfilling social
obligations to many Nigerian Igbo Africans.
Yams store relatively longer in comparison with other tropical fresh produce
and therefore stored yam represents stored wealth which can be sold
all-year-round by the farmer or marketer. In parts of Igboland in
Southeastern Nigeria, it is customary for the parents of a bride to offer
her yams for planting as a resource to assist them in raising a family. Most
of the world production of yam is from Africa about 96% with Nigeria alone
accounting for nearly 75% of the total world production.
