Yam Cultivation


Yam Cultivation: Yam is another tuber crop cultivated majorly in Africa, South American and in most countries of the world. Yams can be eaten when cooked, fried and as flours.

Crop Cultivation: There is a large market for yams, if you are looking towards starting an agriculture crop cultivation business and you live in Africa or South America, then one of your options is to go into cultivation of yam. Yams well preserved in a barn can outlive one season.




Yam is propagated through corm: An ordinary-sized yam gives about 6 – 8 bits for planting. After one or two ploughings, pits of size 60 cm x 60 cm x 45 cm are made at a spacing of 90 cm x 90 cm. For harvesting small to medium sized tubers are used with a distance between pits reduced to 60 cm x 60 cm.

How long does Yam take to grow: about 14 weeks. Yams typically take about 14 weeks to mature. They should be harvested when the tops of plants start to go yellow and wither. Harvesting generally occurs in autumn. Remove yams from the soil.




How is Yam planted: Planting is done by seed yam or cut setts from ware tubers. One day before planting, the tubers have to be subjected to treatment with wood ash or a fungicide (thiabendazole) to prevent damage to the soils. The setts are planted at an interval of 15–20 centimetres (5.9–7.9 in) with the cut face facing up.

What is the best month to plant yam: Preparation Of The Land. Yam is best planted within the months of February and April when the rainy season is just beginning. These are the best periods for land preparation.




What is the best fertilizer for yam: Fertilization is best done at 8- 10 weeks after planting. Fertilizer application is by banding. For low fertility classed soils, 400-500 kg/ha of inorganic NPK 20:10:10 fertilizer is regarded as adequate for optimum yield of yam.

What is Yam Minisett: White yam (Dioscorea rotundata Poir.) is an important tuber crop grown throughout West Africa, the Caribbean, and Latin America. The Yam Minisett Technique (YMT) was introduced in Nigeria in the late 1970s as a means of increasing the production of seed yams.




Is Yam an annual crop: Yams (Dioscorea spp.) are annual or perennial vines and climbers with annual or perennial underground tubers. They belong to the Dioscoreaceae family. This tuber-producing plant is popular in the humid and subhumid tropics, particularly in Africa, the West Indies and parts of Asia and South and Central America.

Where do yams grow best: Yams grow best in moist, well-drained soil. They do not grow well in heavy, waterlogged soils, so if your soil is not light and well-draining, amend it thoroughly with plenty of organic matter such as compost. Yams are heavy feeders and this will benefit their root growth.




What is the season for yams: Sweet potatoes grow best in abundant sunlight and warm temperatures, and are generally available year around with the peak season falling from late October through December.
