Production of Sweet potato
Over the years, sweet potatoes have been studied, and the means of production have also been improved. Initially, people experimented, but now there are particular things that are known that guarantees better production of this vegetable.

One of the first things that were discovered regarding sweet potato productions is that this vegetable cannot grow in frosty conditions. This explains why it grows well in warmer climates. It is said the best climate for producing sweet potatoes is 24 °C.

The tuberous roots of the sweet potato mature between 2 to 9 months. However, this maturity is directly dependent on the grower and the conditions too. Soil, climatic conditions and the grower’s hand are all important to the growth of the sweet potato.

The adaptability of the sweet potato is limited to warmer climates. If these vegetables are exposed to cold they will not grow. Therefore, the best conditions of them are hot days and warm nights. Growing these plants under these conditions is best because it aids the best production for commercial feasibility. It is also known that longer exposure to sunlight on longer days favors better growth of vines. Short days induce greater root development. This is because the sweet potato stores food, and it must be remembered that the sweet potato like the regular potato is a storage root.

Well-drained soils are best for producing sweet potatoes. The soils should loamy and sandy. As opposed to these soils, you should not use soils that are too heavy or rich in organic matter. Soil acidity should range between a pH 5.5-6.0. Rotation of soil is important due to scurf and Fusarium wilt. The correct balance and rotation of soil will aid better sweet potato production. With experience of using soils of different mixtures, growers have learned to ameliorate production over the years.

Sweet potatoes are usually propagated through vine cuttings called slips. Though slips are used quite a lot for this purpose, the use of sprouts is preferred. These sprouts are selected from stock that is chosen because of its appearance. It is estimated that 7 or 8 sweet potato stock plantings are required in order to cater to one acre. As an example, it is said that for Pacific Northwest growth and production, sprouts should be selected from sweet potato nurseries in California that have a good reputation.

Indeed, the growing or sweet potatoes is a task that requires experts. These vegetables do not just happen to grow well, and they need to be cultivated carefully. Growers have ended learned about these vegetables through experience and developed the best possible conditions to grow them for commercial purposes. Soil conditions, climatic conditions, etc. are important to consider. In addition to this, growers need to know when they should pick out the sweet potatoes, as they need care for them in case they are exposed to damage. Growers therefore need to keep a keen eye on the skin condition of sweet potatoes.

Buying Sweet potato
Buying sweet potatoes may not be the same as shopping for other vegetables. This is because of the different types of sweet potatoes available in the market. Unless you were to have labels on each kind of sweet potato, you would not know what type of flesh it has on the inside. However, one indication of an orange-fleshed sweet potato is that it tends to be a bit plump. Its skin would also be slightly on the reddish side. On the other hand, the yellow-fleshed sweet potato tends to be a little narrow in appearance along with having a tanned skin color. Yet, it is sometimes difficult to buy what you really want by simply using your visual judgment. It is advised that you ask the manager in a store for what type of sweet potato you want.

When buying sweet potatoes you need to select ones that are a bit heavy in comparison to their size. This obviously means that they are denser in content. You need to also try and buy those sweet potatoes that are similar in size as well, as it helps when you are cooking them as whole vegetables. When you cook whole vegetables like the sweet potato they should approximately be of similar size so that they cook uniformly. Larger sweet potatoes usually would take a little longer to get cooked.

In addition selecting sweet potatoes that are a bit dense and of similar size, you should aim at buying ones that are smooth and hard. The sweet potatoes you buy should also be free of bruises or signs of decay. Signs of decay usually include sweet potatoes appearing shriveled or having sunken portions or black spots on their skins. Also, if you try to remove these decay signs from the sweet potato, it may already have done its damage by spoiling the flavor of the whole potato.

When you buy sweet potatoes, you need to be aware of the conditions that they have been kept under. This is because the conditions would determine the texture of this vegetable. If they are maintained in a refrigerator, the taste of the sweet potato could easily change. However, they can last and taste well if they are maintained in cool and dark areas that are sufficiently ventilated. Once you cook this delicious vegetable, the sweet potato can last up to a week in a refrigerator.

As opposed to buying sweet potatoes that have been maintained in a cool and dark area, keeping them in places that have temperatures higher than 60° F. would cause them to develop woody characteristics and sprout quicker than they should.

Sweet potatoes can be used in a number of ways to make a variety of dishes. Lime, ginger, cinnamon, honey and nutmeg are some of the ingredients that go well with sweet potatoes. You may also use sweet potatoes in the form of breads, baked desserts and quick puddings, stews and croquettes. In addition to these dishes mentioned here, there are several others that may be made from the versatile sweet potato.

Sweet potato Variations
One of the most versatile vegetables you can come across is the sweet potato. Its variations make it an interesting vegetable that has a long trail of history to it. Like several vegetables that were planted in far off locations by travelers and conquerors, variations of the sweet potato managed to find their way to different locations. Of course, it is the people living in these areas that were fortunate enough to receive this vegetable.

Generally, there are two types of sweet potatoes: One is moist and the other is dry. The moist sweet potato is known to be the orange-fleshed one while the dry sweet potato is known to be the yellow-fleshed one.

The variations of the orange-fleshed sweet potato are well known in the United States markets. However, there are many people who prefer the yellow-fleshed sweet potato, which is the starchier kind.

The orange-fleshed or moist-fleshed sweet potatoes are sometimes known as yams, but the real yam is quite large, and may be as heavy as a hundred pounds. Yams are actually from Africa, but commonly some variations of the sweet potato is called a yam.

The Ipomoea batatas, a sweet potato, is also an American native plant. Christopher Columbus and his crew discovered this type of variation. However, the exact location where this variation of sweet potato was discovered is not traceable, as there is no accurate record of it.

‘Axi’ was another name by which the sweet potato was known near the coastal region of Yucatan and Honduras. Among the natives in this region, the sweet potato was also known as batatas or betatas. As far back as 1514, the sweet potato had 9 known varieties. In Spain alone, the sweet potato was cultivated and more variations of this vegetable were grown. Some of these variations of the sweet potato included purple, red, and pale or white ones.

The reason for the different variations produced was due to the fact that the soil, climatic conditions and other important factors varied. When the sweet potato was taken to different regions, new variations became possible because of the different conditions this vegetable was grown under. However, it appears that the sweet potato did not grow well in some locations. For example, it could not be grown in Belgium when attempted in 1576. John Gerarde claimed to have also grown sweet potatoes in England, and that they were known in warmer climatic areas such as India. The accuracy of this cannot be guaranteed. Also, explorers from Spain had transported sweet potatoes to other locations from where the sweet potato was taken to places like China, India, and Malaya.

In view of the amount of attention the sweet potato received in its earlier days recorded, it cannot be denied that the sweet potato was an important vegetable no matter what its variations were. Whether the sweet potatoes were fleshy or had various colors of skin, they were considered to be important variations.

Preparing Sweet potato
Many people have developed different ways of preparing sweet potatoes. Prior to cooking them, there are particular things that you could do to ensure good taste and longer periods of storing sweet potatoes. To begin with, for the greatest food value, you are advised to select sweet potatoes that have a deep orange color. This means that when you first buy them, you need to select the best sweet potatoes, and make sure they are firm roots. However, you need to handle them carefully from the time you buy them till the time you decide to cook and eat them.

The basics of storing sweet potatoes prior to preparing them include storing them in a cool and dry place. Never refrigerate sweet potatoes.

You need to wash your cured sweet potatoes. Cured sweet potatoes are those that have been through their initial storage process that includes storing them at high temperature. After washing them, bake the cured sweet potatoes or boil them until they have turned a bit soft.

The next thing to do with the cured sweet potatoes while preparing them is to cool them. If they have been boiled, you need to drain the sweet potatoes thoroughly and cool them subsequently. After this step, wrap up the sweet potatoes in plastic or foil individually with their skin left on.

Since sweet potato dishes usually freeze easily, they save time and energy. Therefore preparing them in this manner is feasible. What you could do is bake several sweet potatoes together. This saves a great deal of time because you can always freeze them to be used days later. Their taste does not go bad even if you store them up to 10 days after boiling or baking them.

If you use fresh sweet potatoes (ones that are uncured) it is better for you to boil them. These boiled sweet potatoes are best used for preparing dishes in which fruits and syrups are used. This is because uncured sweet potatoes usually do not have enhanced sweetness as cured ones do. Therefore, curing potatoes the way that growers do enhances their quality for cooking.

Canned or frozen sweet potatoes are also used as substitutes in some dishes that need cooked ones. They may substitute fresh sweet potatoes. Using these substitute sweet potatoes means that they are generally smaller than the others. This is because they have been canned of frozen, which causes their size to shrink. Alternatively, for the sake of canning, the potatoes may be cut smaller in size. Due to the size difference between fresh sweet potatoes and canned or frozen ones, there is need to balance them out. It is thought that 6 to 8 canned sweet potatoes roughly equate to 4 medium-sized fresh sweet potatoes. Finally, whatever type of prepared sweet potatoes you use for cooking, they all prove to be very useful in saving a great deal of time.
