This taters whiteflesh is sweet, creamyand ideal for soupsand stews.

Japanese sweetpotatoes have redskin and dry, whiteflesh. Roast these up

with a few of yourfavorite root veggiesfor a colorful sidedish.

Because sweet potatoes are vegetatively propagated and because

uniformity in appearance of roots is essential, it is important to

choose a variety that will suit your soil type, market requirementsand weather conditions. It is advisable to plant at least two varieties

each year because no single variety performs best on all soil types

and under all climatic conditions. Below is a comparative table to help

you with your choice.

Covington Sweet PotatoesJan 4, 2012 at 12:17 pm|

With 972 million pounds of production in 2010, North Carolina is the dominant producer of

sweet potatoes in the United States. The sweet potato was named our State Vegetable in

1995, and NC farmers have continued to advance its production through the years,

accounting for roughly 40% of sweet potato production in the US. One recent advance by

the Sweet Potato in North Carolina was the introduction of the Covington Sweet Potato.

3/3

For years, the dominant sweet potato variety in North Carolina, and most of the country

was the Beauregard Sweet Potato. Beauregards produce good yields, are considered quite

sweet, and are relatively disease and pest resistant. Recently, however, a new variety of

Sweet Potato has been gaining favor with North Carolina farmers, the Covington Sweet

Potato. The Covington variety was developed by NC State University in the late 90's to

early 2000's, and was released by the North Carolina Agricultural Research Service in

2005. The variety was named after a popular and esteemed sweet potato scientist at the

university, Henry M. Covington. Since its release in 2005, local growers have been

devoting more and more land to its cultivation. The primary benefit of Covington Sweet

Potatoes over other varieties is that they tend to grow more uniform in shape, which makes

them much more marketable to retailers and food service establishments. Covingtons are

also less likely to grow into the "jumbo" grade, which are too large for many cooking

applications, making them difficult for farmers to sell. Many growers also feel that

Covingtons grow and produce better than other sweet potato varieties. Many feel that they

end up with less pest damage, and that their ultimate yields after grading are better with the

Covington variety. While the data is too limited to tell for sure, overall sweet potato yields as

measured and recorded by the USDA have increased noticeably in major Covington

producing states like North Carolina and California, since the release of the variety in

2005.
