Yam Cubes


Yams are tropical tuber crops. They are mainly cylindrical in shape, with rounded ends. The bark is mostly light brown when harvested and darkens during storage. They are a major staple in Nigeria. There are many varieties of yams but the most common are white yam (which is also referred to as the sweet yam), the yellow yam and the water yam. Yams are mostly popular because they are used to prepare a wide variety of quick recipes.

Yam is planted during the beginning of the Nigerian rainy season which is in the months of March through May. The first sets are harvested in late July with the last batch harvested in early December.


Yam can be stored for several months and it will still retain its taste. It is best stored in a cool, dry and well ventilated place. Raw yam should not be stored in very cold temperatures eg the refrigerator as this changes the taste.

Buying Guide

Yam is readily available in the open Nigerian markets or African food stores all over the world. However when buying yam in non-African shops abroad, be aware that some produce labelled as yam is not really yam but some variety of tuber crops that may be better classified as sweet potato.

Since yams are harvested from the month of July, they are cheapest at this time of the year then become increasing expensive as the next planting season approaches.

When buying yam, ask for white/sweet yam. This is the tastiest of them all unless a doctor prescribed water yam for you. Before you buy, carry out visual inspection of the yam. Press all parts of the tuber to make sure that it is firm all over. Soft parts are the first indication that the yam is going bad. Also, avoid the ones with bruises or cracks as much as possible. Most bruises occur during harvest and cause the affected part to go bad.


Yams are rich in dietary fibre, vitamin B6 and C, potassium and manganese.
