Successful cassava farming starts with selecting the right site: well-drained soil, pH between 5.5 and 7.0, and full sunlight.

While cassava can do well in most soil types, here are some requirements that can boost its yield from research.

Avoid flood-prone or drought-heavy areas. Land preparation includes clearing weeds, shrubs, and debris using hand tools or machines.

Soil testing follows to check pH and nutrient levels. Based on the results, you can apply organic matter or fertilizer to improve soil health.

For large farms, tractors and tillers save time. Irrigation planning is also key, especially where rainfall is inconsistent.

Tools like hoes, shovels, and rakes are enough for small farms. Careful preparation gives cassava a strong start, leading to better growth and higher yields.

This stage lays the foundation for efficient planting and long-term success in cassava cultivation.

Here are things to keep in mind:

  • Soil pH: Cassava thrives in slightly acidic to neutral soils (5.5–6.5); extreme pH levels must be corrected to support healthy growth.
  • Soil Texture: Cassava grows well in loose, loamy soils; balanced texture supports root development, drainage, and easy harvesting without stunting roots.
  • Soil Fertility: Cassava needs balanced nutrients. Fertilizers improve yield in poor soils by supplying nitrogen, phosphorus, potassium, and essential micronutrients.
  • Soil Water Holding Capacity: Cassava needs moist soil early on. Good water-holding capacity helps roots access moisture during dry periods, boosting growth.
  • Soil Temperature: Ideal cassava growth occurs in 25–29°C soils. Growth slows under 10°C but tolerates slightly hotter conditions if moisture is stable.

Cassava Planting Techniques: What You Need to Know

Techniques for planting cassava

Getting cassava farming right starts with what you plant. If you want a healthy harvest, start with clean, disease-free stem cuttings.

Choose cuttings 20 to 30 centimeters long from the middle part of a mature cassava stem.

This section has the strongest buds and gives you a better chance of quick, even sprouting.

See more about cassava stems.

Best Time to Plant Cassava

Timing matters. Cassava grows best in warm climates with steady rainfall. In tropical areas, plant just before the rainy season.

This helps the roots settle and grow faster. If your area doesn’t get much rain, make sure you have a way to water your fields, especially in the early stages.

How to Space and Plant Cassava Cuttings

Proper spacing helps your plants grow well and makes harvesting easier. Leave about 1 meter between rows and 0.8 meters between plants in the same row.

Plant each cutting 5 to 10 centimeters deep to keep it steady in the soil and avoid rotting from too much moisture. Here is the intra-row and inter-row spacing for cassava.

See how to plant cassava cuttings.

Choose the Right Planting Method

You can plant cassava directly in the field or use nursery transplants if that’s common in your area. The best method depends on your climate, land type, and tools.

Whichever you choose, make sure the soil is loose and rich with organic matter so roots can grow freely.

Soil Prep Makes a Difference

Before planting, clear the land, remove weeds, and prepare the soil by tilling or adding compost if needed. Good soil conditions make a big difference in root formation and final yield.

When you use these simple, proven techniques, you’re not just growing cassava, you’re setting yourself up for a productive and profitable harvest. Here is more on soil preparation for cassava farming.

Cassava Crop Management and Production

The production of cassava involves a chain of steps before it is used to produce its numerous products and gets to the final consumer.

Managing your cassava crop correctly is the key to ensuring a healthy harvest. Without proper care, your plants may struggle to grow, leading to lower yields.

One of the most important steps is controlling weeds. Weeds can steal nutrients, water, and sunlight from your cassava plants, so it’s crucial to keep them in check.

Weed Control Methods

To control weeds, you can use several methods: mechanical weeding, manual removal, or even cover crops.

For larger fields, mechanical weeding is a great option because it saves you time and labor.

Cover crops, like legumes, can also suppress weeds and improve soil fertility, making your soil more fertile for cassava growth. See more on cassava weed management.

Mulching for Better Growth

Mulching is another effective technique. By applying organic or plastic mulch around your cassava plants, you can keep the soil moist, which reduces the need for constant irrigation.

In addition, mulch helps stop weeds from growing and adds nutrients to the soil as it breaks down, improving your plants’ overall health and boosting your yield.

Intercropping to Maximize Land Use

Consider intercropping, and growing cassava alongside other crops. This helps you make the most of your land, increases biodiversity, and may improve pest management.

Intercropping cassava with legumes, for example, can enrich the soil with nitrogen, a natural nutrient that benefits your cassava plants.

You can also practice crop rotation to maintain healthy soil and keep pests in check.

Here is more on intercropping cassava.

Fertilizer Application: Balancing Nutrition

Fertilizing your cassava plant is also essential for healthy growth. Organic fertilizers, made from plants or animal sources, improve soil health over time.

They boost soil structure and support microbial activity.

Chemical fertilizers, on the other hand, offer quick nutrients but should be used carefully to avoid damaging the soil.

A balance of both can provide your cassava with the nutrition it needs without harming the environment.

By applying these crop management practices, you’ll help ensure strong, healthy cassava plants and a bountiful harvest.

The key is to manage weeds, maintain soil health, and balance fertilizer use, all of which contribute to the long-term success of your cassava farming.

Harvesting

Soil texture for cassava planting

Harvesting cassava roots at the right time ensures optimal yield and quality. Cassava is typically ready for harvest 10 to 12 months after planting.

Indicators of maturity include yellowing leaves and roots at least 2 inches in diameter. Healthy foliage and a strong stem structure also suggest readiness.

During harvesting, use a sharp spade or machete to gently loosen the soil around the roots, avoiding damage.

Once exposed, roots should be carefully pulled from the ground and cleaned of excess soil. Post-harvest, cassava should be stored in a cool, shaded area to prevent spoilage.

If not processed immediately, store the roots in a well-ventilated space, maintaining proper moisture levels to avoid decay or dehydration. Here is an in-depth guide on harvesting cassava roots.

Storage

As soon as cassava is harvested and left above ground, it starts the fermentation process which is why an effective storage technique is necessary.

Depending on what the harvested cassava is going to be used for, the storage technique will differ.

In my traditional farming community where the primary use of cassava is the production of garri, fufu, pudding, and other cassava-based foods, cassava is typically stored immediately after harvesting to prevent spoilage.

The tubers are left under a shed with open sides for ventilation for one day after harvest before peeled and the other processes commence.

It is important to keep it away from moisture and sunlight as these will hasten the chemical breakdown of the components.

Another method is covering the roots in a trench or pit, covered with soil or sand, and kept at a consistent temperature.

This method helps maintain the roots’ quality and prevents decay. For longer storage, cassava can be cured by drying the roots in the sun or using a controlled drying process.

This process helps remove excess moisture and prevents the growth of mold and bacteria, allowing the roots to be stored for several weeks or even months.

See an in-depth guide on how to store cassava roots.
