Origin of Cocoyam
Cocoyam or taro originates in Southeast Asia. Early cultivators domesticated the plant in the Philippines, and it spread to Africa, the Caribbean, the Pacific islands and other tropical areas. Cocoyam remains an important staple crop for millions of people in developing nations.
The plant grows from starchy tubers called corms that produce heart-shaped green leaves and small flowers. The two main types are Colocasia esculenta and Xanthosoma sagittifolium. Colocasia, known as taro, produces larger corms and leaves. Xanthosoma, or tannia, has smaller corms and more edible leaves.
Cocoyam thrives in hot, humid climates with fertile, well-drained soil and plenty of moisture. The starchy corms provide an important source of carbohydrates, while the leaves offer fiber, protein and various vitamins and minerals. Cocoyam remains a staple food in tropical regions of the world.

Propagation
Propagation of cocoyam can be done through corms, cormels and stem cuttings. The most common method is using corms. Corms are rounded swollen underground stems that contain stored food and buds that can produce new plants. Select corms that are healthy, disease-free and at least 200g in size. Bury the corms 8-10 inches deep in a nursery bed with well-drained soil and compost or manure. Space the corms 18 to 24 inches apart. Regular watering and fertilization will boost growth.
Cormels, which are small cormlets that develop from the axillary buds of the main corm, can also be used. Detach cormels from the main corm and treat them like mature corms. Stem cuttings with at least two nodes should be cut from young stems. Remove leaves from the bottom node before planting in a well-draining rooting medium. Provide shade and misting to prevent drying out. Once rooted, transplant into pots or nursery beds.
Within 3 to 4 months the corms and cormels will produce new corms for harvest. The stem cuttings will be ready in 2 to 3 months. Cocoyam propagation allows farmers to multiply plant materials and produce new varieties. Home gardeners can also get planting materials to start their own cocoyam crop.
How to Cook and Prepare Cocoyam
To cook cocoyam, first peel off the tough, brown skin. Then cut the white flesh into chunks. Boil or steam the cocoyam until tender when pierced with a fork, about 15 to 20 minutes. Mash or dice the cooked cocoyam as desired. It has a mildly nutty flavor and a texture similar to potatoes when cooked.
Cocoyam can also be fried, baked, or roasted. To fry, slice cocoyam into wedges or chips, coat with oil and your favorite spices, and fry in a pan over medium-high heat until lightly browned, turning once, about 10 minutes total. To bake, toss with oil and spread on a baking sheet. Roast at 400 F, stirring once, until tender and lightly browned, about 25 minutes.
Cocoyam leaves, known as kontomire in Ghana, can also be cooked and eaten like spinach. Blanch the leaves in boiling water, then chop and add to soups, stews, or omelets. The leaves have an earthy, spinach-like flavor and are high in nutrients like protein, calcium, and vitamins A and C.
In many cuisines, cocoyam is also ground into flour or meal to make dumplings, porridge, and bread. Grind the boiled cocoyam chunks into a smooth paste, then shape into balls and steam as dumplings. Or mix the cocoyam flour with boiling water to make a thick porridge, often eaten for breakfast. Cocoyam flour can also be used in pancakes, cakes, and bread for a nutritious alternative to wheat flour.
Conclusion
Cocoyam is a versatile crop with many important uses, especially as a staple food source and for its industrial and medicinal applications. Its ability to thrive with little inputs has made it an integral part of livelihoods in tropical regions.
