Caribbean White Soft Yam

Yams are often mistakenly called sweet potatoes and vice versa, but these are actually two different vegetables. A true yam is the tuber of a tropical vine and it's not even distantly related to the sweet potato. Yams are a popular vegetable in Africa Latin American and the Caribbean. This tuber can grow over seven feet in length. 

The yam's botanical name is dioscorea batatas.
Depending on country and region, it may also be called a boniato, njam, nyami, djambi, yamswurzel, ñame or igname de chine.
How to Identify a Real Yam 
True yams are indigenous to Africa and Asia with most being grown in Africa, but there are over 150 varieties of yams available worldwide. True yams have rough, dark skin. Their flesh can range from white to a reddish color, and yellow but it's usually white. 
Although you might find canned vegetables labeled as yams, these probably aren't true yams. Even the "yams" found in fresh produce sections of grocery stores are rarely real yams. They're soft sweet potatoes, which are different from firm sweet potatoes.
Africa, the native land of the yam, grows 95 percent of more than 600 varieties of the crop. Yams favor tropical and sub-tropical weather during their growing season and do not tolerate freezing.

Tuber Cuttings
After harvesting, yams have a resting period for about three to four months throughout the dry season before they make suitable seeds. Disease-free plants produce suitable cuttings for growing yams and need planting before they sprout, usually in August. Gardeners cut tubers crosswise into three pieces. The cuttings lie out for one week to callous over after being washed with Bordeaux mixture, a solution of copper sulfate and lime in water, to protect them from diseases such as tuber rot.

Soil Preparation
Yams favor loose clay soil with good drainage. Gardeners test soils and adjust pH levels to about 5.5. They plow the planting area and dig trench rows with 3 1/2 feet between them. Gardeners then add compost into the trenches and check the soil for proper drainage. Tuber crops do not grow well in overly wet soils and require loose soil to allow room for drainage and growth.

After the tuber cuttings have lain out for one week, gardeners plant them 2 inches deep into the trenches with 18 inches between each planting. Gardeners lay mulch along the trenches after initial planting. Mulch keeps the ground moist without drowning the crop, protecting the tubers from extreme heat. About one month after twines emerge, gardeners place stakes into each mound at an angle to meet the stake in the adjacent mound, creating an A-frame structure for the two twines to climb and meet. The vines of yam plants are not sturdy and need support to produce high yields.
