Nigeria is the world’s biggest yam producer, making up 70-76% of global yam farming. Yams are a key food in Nigeria, giving us 200 calories of energy every day. In 2008, Nigeria’s yam production almost doubled from 1985, hitting 35.017 million metric tonnes. This was worth a huge US$5.654 billion.
Yam farming is very important in Nigerian agriculture. It helps a lot with our food and economy. Yams are also a big part of our social and religious events.
Nigeria’s lead in yam farming is key to understanding tuber crops. It shows how important they are for our agriculture.
Understanding Nigeria’s Position in Global Yam Production
Nigeria is the top yam producer in the world. It makes over 65% of the world’s yams, with 38 million metric tons in 2012. This shows Nigeria’s strong farming skills and how important yams are to its economy and food.
Nigeria’s Contribution to World Yam Output
The land used for yams has grown from 1.15 million hectares in 1961 to 5.04 million hectares in 2012. Yam production worldwide has also grown, from 8.32 million metric tons in 1961 to 58.75 million metric tons in 2012. Nigeria leads, making over 65% of the world’s yams.
Economic Impact of Nigerian Yam Industry
The Nigerian yam industry is worth $7.75 billion. In 2012, Nigeria grew yams on about 2.9 million hectares of land. The profit from each yam seed was over $13,000 per hectare, showing how profitable this industry is.
Key Yam Production States
Some Nigerian states are big in yam production. Benue, Taraba, Niger, Adamawa, and Nasarawa are the main ones. Benue State is called Nigeria’s “food basket” because of its high yam yields. The Zaki Biam International Yam market in Benue State is the biggest of its kind in Nigeria.
Essential Yam Species and Varieties in Nigerian Agriculture
Nigeria has many yam species, each special in its own way. The white yam (Dioscorea rotundata) and water yam (Dioscorea alata) are the most important. They are key to the country’s economy.
The white yam is loved for its taste and is in high demand. It grows well in many places, like coastal areas and forests. This shows it can adapt to different environments.
The water yam is also very valuable. It has a deep purple color and grows best in certain areas. It can produce up to 15 tons per hectare, making it very productive.
Nigeria also grows other yams like Dioscorea bulbifera (aerial yam), Dioscorea dumetorum (trifoliate yam), and Dioscorea esculenta (lesser yam). These add to the country’s yam diversity and value.
Nigeria is a big player in yam production worldwide. It grows over 600 yam varieties, making up 95% of global yam production. This makes Nigeria the top yam producer and exporter.
Land Preparation and Soil Requirements for Yam Farming in Nigeria
Yam farming in Nigeria needs careful land preparation and soil selection. Yams grow best in free-draining, sandy, and fertile soils. Knowing the soil needs and preparation methods is key for a good harvest.
Soil Type Selection and Testing
The best soils for yams are sandy loam and silt loam. These soils drain well and have the right nutrients. Yields can also be good in clay loam soils with lots of organic matter. But, avoid planting yams on hard, stony soil.
Soil testing is important before starting. It shows nutrient levels and needed amendments. This helps farmers choose the right fertilizers and prepare the soil for yams.
Mound and Ridge Making Techniques
- The traditional method makes mounds 1 meter high for yam farming.
- Some farmers like making ridges for better drainage and soil structure.
- Yam setts should be 60g to 100g for better yields.
Land Clearing and Preparation Timeline
White yam planting is from March to April. So, start clearing and preparing the land before the rainy season. This means removing plants, tilling, and making mounds or ridges.
| Soil Nutrient Requirement | Quantity Removed per Hectare |
|---|---|
| Nitrogen | 128 kg |
| Phosphorus | 17 kg |
| Potassium | 162 kg |
Good land preparation and the right soil are key for high-yielding yams in Nigeria.
Planting Methods and Best Practices
In Nigeria, how you plant yams is key to a good harvest. Traditionally, farmers use seed yams or cut setts. But, the yam minisett technology has changed this, making planting more efficient.
The yam minisett technique cuts yams into small pieces, about 25-50 grams each. This can make 20 new yams from one seed yam. It boosts yield and makes planting easier. Yet, not many farmers use it because it takes longer and doesn’t work well with other crops.
To plant yams, start by loosening the soil with a broadfork. Then, shape the beds with a digging hoe. This helps the soil breathe and supports the yams’ growth. Plant the cut setts 15-20 centimeters apart, with the cut side up.
Soil health is vital for yams. Animal manure is better than chemical fertilizers. It adds nutrients and improves soil structure. Also, keep the soil moist to help the yams grow well.
Weeds can harm yams by competing for resources. Use a hoe to weed between rows and around the plants. This keeps the crop healthy and productive.
| Yam Variety | Description |
|---|---|
| Lisbon Yam | A popular variety with a white flesh and smooth skin |
| Yellow Yam | Characterized by its vibrant yellow flesh and slightly sweet taste |
| Potato Yam | A starchy variety with a texture and flavor similar to white potatoes |
| Purple Yam | Distinctive for its deep purple flesh and rich, creamy texture |
By using these planting methods and best practices, Nigerian farmers can increase their yam yields. This helps Nigeria stay a top yam producer worldwide.
Cultivation Techniques and Farm Management
Yam farming in Nigeria needs careful planning for a good harvest. Staking, mulching, and weed control are key. These steps help yam farming succeed in the region.
Staking Methods and Materials
Staking is very important in yam farming. Nigerian farmers use two 2-meter wooden stakes for each pair of yam plants. This helps the vines grow up and get more sunlight. It also stops the tubers from rotting.
Mulching Practices
Mulching is very important in yam farming, mainly in October-November. Farmers use dry grass, leaves, or other plant debris to cover the soil. This keeps the soil moist, stops weeds, and makes the soil better over time.
Weed Control Strategies
Weeds can harm yam plants by taking their nutrients and water. Nigerian farmers use hoes to remove weeds three to four times. This hard work helps the yams grow well.
Intercropping is also used in Nigerian yam farming. Maize, cassava, or vegetables are grown with the yams. This makes the farm more resilient to the weather and keeps pests away.
Fertilizers are key for high yam yields. Nigerian farmers apply 400-500 kg/ha of NPK 20:10:10 fertilizer after 8-10 weeks. This is based on soil tests.
Disease Control and Pest Management
Yam farming in Nigeria has many pests and diseases. These can hurt crop yields and quality. We need good management to grow yams well.
Nematodes and insects like beetles and crickets are big problems. Fungal diseases like anthracnose also cause a lot of damage. We must find ways to control these issues.
To fight pests and diseases, we use different methods. Growing disease-resistant yams is a good start. Keeping the area around the field clean helps too.
Chemical pesticides are used, but they can harm the environment and people. We need a better way to manage pests and diseases.
Using a mix of methods is key. This includes cultural, biological, and chemical controls. Regular checks and quick action are important for healthy yam farms in Nigeria.
By knowing how to manage pests and diseases, farmers can grow better yams. This helps the Nigerian yam industry grow and succeed.
| Pest/Disease | Impact | Management Strategies |
|---|---|---|
| Nematodes (Root Knot and Yam Nematode) | Causes dry rot, deformed tubers, and reduces market value and quality by up to 32-59% |
|
| Yam Shoot Beetle, Yam Tuber Beetle, and Crickets | Damage to plants and tubers, leading to reduced yields and quality |
|
| Anthracnose, Yam Mosaic Virus, and Dry Rot | Cause significant yield losses, reduced tuber quality, and marketable value |

Harvesting and Post-Harvest Handling
Yam harvesting is key in farming. It affects the quality and amount of yams. In Nigeria, the best time to harvest is before the vines and soil dry out.
Farmers can get 10 to 15 tonnes per hectare of white yam. Water yam yields 16 to 25 tonnes per hectare.
Optimal Harvesting Time
The best time to pick yams is when leaves and vines start to fade. The soil should be slightly soft. This usually happens 6-8 months after planting.
Harvesting at the right time means the yams are fully grown. They will have the right shape and size.
Storage Techniques
- Yams are tied together and stored in a cool, dry place. It should be well-ventilated.
- The storage area must keep out rodents. It should have a metal base and wire netting.
- It’s important to check and remove bad yams often. This keeps the quality high for about 5 months.
Market Preparation
After harvesting and storing, yams are ready for market. They are cleaned and any bad parts are removed. They are sorted by size and quality.
Good preparation makes yams look nice. It helps farmers get a good price for their yams.
Good handling after harvesting is key. It helps reduce losses and keeps yams fresh for consumers. Nigerian farmers can improve their yields and help the country’s economy by following these practices.
| Metric | Value |
|---|---|
| Nigeria’s Share of World Yam Production | 75% |
| Total World Yam Production (1995) | 32.7 million Mt |
| Total World Yam Production (2000) | 37.5 million Mt |
| Yam Exports (2000) | 23,198 metric tons |
| Post-Harvest Losses in Nigeria | 20% to 67% |
Cultural and Economic Significance
Yam is very important in Nigeria, mainly in the southeast. Every year, yam festivals celebrate the harvest. These festivals are full of life and show how much yam means to the people.
In some places, a man’s wealth is shown by how much yam he grows. Yam is also key in marriage, where a groom must give 200 big tubers to his in-laws. This shows he can take care of his family.
Yam is not just important culturally. It also helps Nigeria’s food and rural economy. Nigeria grows the most yam in the world. They harvest about 36.72 million metric tonnes every year.
The yam economy is a big part of Nigeria’s farming. It gives jobs, money, and food to many people, mostly in rural areas.
Studies on yam farming in Nigeria are very interesting. They show that mostly men farm yam. They also found that experience, age, and being married matter a lot. Knowing this helps make the yam industry in Nigeria better.
