Yam is a staple food crop in Africa and Asia. The plant is closely related to taro, another root crop that grows in similar conditions. Yam is a tropical plant that needs warm soil, plenty of water, and sun to grow well. If you live in an area where yams are grown commercially, you can buy seed tubers from a local nursery or grow them from seed.
Yams are a popular crop with gardeners and farmers alike because they’re easy to grow and they have a high yield. Yams can be grown as an ornamental plant or for food. They thrive in warm climates and need plenty of sunlight. When planting yams, choose a sunny spot that receives at least 6 hours of sunlight a day. Dig a hole about 4 inches deep and add some compost to the soil before planting. Water your yam plant well after planting it so it will take root quickly. You can also use stakes when growing yams so that they don’t fall over as they grow taller.
You can harvest your yam crop once it reaches maturity (usually about 3 months after you’ve planted it). If you want to eat the tubers from your yam plant, then harvest them when they’re about 2 inches wide and 1 inch thick; otherwise, leave them on the vine until they get larger if you plan on using them for ornamentation purposes only.
Yam is one of the most popular and nutritious food crops in the tropics. It is a perennial crop with underground storage organs called tubers that are used as food. Yam is an important staple crop in West Africa, Central America, and the Carribean. In Nigeria for example, yam accounts for about 30% of all roots and tubers produced. Many people have not mastered the art of growing yams on a large scale because it requires careful planning and preparation. In this article you will learn how to plant and harvest yams successfully.
How to plant and harvest yam
How to plant and harvest yam?
Yams are perennial crops, meaning that they grow for more than two years. The best time to plant a yam is during the rainy season or dry season when there is no heavy rainfall. They can be planted from October through August but after the December holidays, as this will give them enough time to mature before the next planting season begins in June or July.
The soil should be fertile, well-drained, and deep (at least 3 feet). A pH level above 5.5 is best for yams; if your soil has a pH lower than this, make sure you add lime or wood ash until it reaches 6-7 on your garden tester before planting your yams.
Plant tubers horizontally with the eyes facing up with their roots spread out near them; this will help prevent rotting while allowing easy drainage of excess water later on in case there’s heavy rainfall during monsoon season.
You should also make sure not to bury too deep into mud–keep them at least 6 inches under ground level so they don’t rot over time due to excessive moisture around their stems which could lead roots into decay as well.
When to plant yam
Yam is a warm-weather crop and can be planted in spring, summer and fall. It should be planted in a sunny location with plenty of moisture. When preparing your soil, make sure to use compost or other organic materials to ensure your yam has all the nutrients it needs to grow well.
Yams prefer sandy loam soils that drain easily, so avoid planting them in heavy clay soils or areas that flood during heavy rains. Make sure your soil is fertile by adding compost and fertilizers before you plant your yams — this will keep them strong and healthy throughout their growth cycle
Soil type for yam cultivation
When it comes to yam cultivation, you will need well-drained soil that is rich in organic matter. Yam plants are tolerant of acidic soil and can thrive in soil that has a pH of 5.5 to 6.8 (slightly acidic). The best time to plant your crop is during the fall months because they do not like cold winters or hot summers, so try to avoid planting them in late spring or early summer. They also require full sun exposure throughout their growth cycle, so make sure you have a spot where there is no shade cast by trees or other plants.
Yams benefit from crop rotation as this helps prevent diseases from developing on the roots. So if possible try rotating different crops every year instead of growing only one type each season (and then switching back again). If this isn’t possible at least rotate varieties within each family–you can even rotate between species within each genus as long as they belong together (i e sweet potatoes/yams).
Planting method for yam
If you want to grow yams, you will need to dig a hole that is about the same size as the yam. The soil should be loose and soft. Then plant your yam at a 45 degree angle so that it can go into the ground easily. Put some soil on top of your yam to cover it up before covering it with more soil all around until there is no more dirt showing from above where your plant is planted in anticipation for growth throughout autumn season months ahead.
Disease that affects yam and how to treat them
There are several diseases that affect yam and how to treat them:
- Neem oil – This oil can be used as a pesticide. It is not harmful to animals or humans, but can help prevent or reduce the incidence of some fungal diseases in yam. It is also effective against insect pests like thrips and whitefly.
- Copper sulphate – This fungicide is effective in preventing powdery mildew on the leaves of yams in greenhouses where it does not get enough ventilation during periods when humidity is high. However, it should not be used for outdoor cultivation because copper may accumulate in soil over time and become toxic to other plants growing nearby (such as those grown at another time).
- Potassium permanganate – Also known as KMnO4 or potassium manganate(VII), potassium permanganate can be applied either mixed with water or diluted with water before spraying onto affected areas on your plant itself — including its roots.
Harvesting methods for yam
There are several methods of harvesting yams, depending on the type and size of the plant you have.
- For small-fruited varieties, such as sweet potato (Ipomoea batatas), you can simply pull the entire plant up by the stem and shake off excess dirt. If you’re growing a larger variety like oca (Oxalis tuberosa) or a horseradish rootstock such as ‘Cooke’s Prolific’, just cut off what you need at ground level with a sharp knife or garden shears.
- For large-fruited varieties like taro (Colocasia esculenta), first use a shovel to carefully dig around where your bulbs are buried and gently lift them out of their hole; then cut each bulb into separate pieces using garden clippers or pruning shears after shaking off excess soil. Be sure to wear gloves when handling yams because they’ll leave a sticky residue on your hands until washed away with soap and water.
Now you know how to plant and harvest yams.
Planting and harvesting yam is easy. Yams are a good source of vitamins and minerals, so you can enjoy them fresh in salads or cook them up for dinner. If you’re growing yams in your backyard garden, they grow best in a sunny spot that gets plenty of water. In the springtime, plant a few pieces of yam seed in the ground and wait until harvest time to enjoy your tasty treats.
