What is the best month to plant cassava in Nigeria?

The best month to plant cassava in Nigeria is at the start of the rainy season in your area. For Southern Nigeria, this means planting between March and May. For Northern Nigeria, the ideal time is between May and June. Your stems need at least 3 months of steady rainfall after planting to build a solid root system.

Planting at the right time ensures your stem cuttings do not dry out in hot soil. When you plant in wet soil, the stem roots quickly and grows healthy green leaves. If you plant when the ground is dry, the heat will burn your stems before they can sprout.

Early Rainy Season Planting (March to May)

Early rainy season planting starts when the continuous rains begin in Southern states. This early start gives your crop enough water to swell its roots before the dry season arrives.

Farmers who plant early usually get higher root weight and early harvests. You should always check that the soil is soaked at least 15cm deep before putting your stems in the ground.

Late Rainy Season Planting (August to October)

Late rainy season planting happens right before the rains start to slow down. This method works best in deep loamy soil that retains underground moisture for a long time.

Your plants will store water in their stems and wait through the dry season. However, you must use drought-resistant stems to prevent your plants from dying during long dry spells.

Regional Planting Differences (North vs South)

Southern Nigeria receives 7 to 9 months of rain every single year. This long rainy window gives Southern farmers two planting options: early planting in March or mid-season planting in July.

Northern Nigeria gets only 3 to 5 months of rain each year. Northern farmers must plant immediately in May or June, or use drip irrigation systems to supply extra water.

Which state in Nigeria is the highest producer of cassava?

Benue State is the highest producer of cassava in Nigeria. The state produces millions of metric tons of cassava roots every year due to its fertile soil and vast agricultural land.

Benue State earned the nickname "Food Basket of the Nation" because of its massive crop output. Other top producing states include Oyo, Ogun, Ondo, Delta, and Cross River.

Benue State: The Food Basket Champion

Benue State leads Nigeria in cassava production because of its rich river basins. The loose soil around the Benue River allows cassava roots to expand deep without hitting hard rocks.

Thousands of smallholder farmers in Benue grow cassava for local staple foods like garri and fufu. The state also supplies fresh cassava roots to major industrial starch factories across the country.

Top Producing States in the South-West and South-South

Oyo and Ogun states lead cassava farming in the South-West region. Their close distance to Lagos makes it easy for farmers to sell fresh roots to city markets and food processors.

Cross River and Delta states lead cassava output in the South-South region. High rainfall levels in these states keep the soil moist, allowing cassava to grow large roots throughout the year.

Expanding Cassava Production in Northern Nigeria

States like Kaduna, Taraba, and Niger are quickly growing their cassava production. Government programs are providing farmers in these regions with fast-growing cassava stems.

Farmers in the North now use irrigation tools to grow cassava even during the dry season. This push is expanding Nigeria's total cassava yield and boosting local farm incomes.

How many months does it take for cassava to mature?

Cassava takes between 9 and 18 months to mature fully, depending on the variety you plant. Early-maturing cassava stems are ready for harvest in 9 to 12 months. Late-maturing traditional stems take 12 to 18 months to build peak starch content.

Knowing the exact maturity age of your cassava helps you plan your harvest time correctly. Harvesting too early gives you light, watery roots with very low starch content. Delaying your harvest too long makes the roots woody, hard, and poor for food processing.

Early-Maturing Varieties (9 to 12 Months)

Improved stems like Dixon cassava stems mature within 9 to 12 months. These high-yield varieties were bred by agricultural researchers to produce heavy roots quickly.

Planting early-maturing stems allows you to sell your crop faster and clear your farmland for the next planting season. They are the best choice for commercial farmers targeting fast cash returns.

Late-Maturing Varieties (12 to 18 Months)

Traditional cassava stem varieties take 12 to 18 months to reach full size. These varieties grow taller and produce dense, starch-heavy roots over a longer period.

Industrial starch factories prefer late-maturing cassava because the roots yield higher dry starch content per ton. However, they take up land for a longer time compared to modern stems.

Signs That Your Cassava Is Ready for Harvest

You will know your cassava is mature when the lower leaves turn yellow and fall off the plant. The soil around the bottom of the stem will also crack open as the expanding roots push upward.

You can test-uproot one or two stands in different parts of your farm. If the roots are thick, firm, and white inside, your whole cassava farm is ready for harvesting.

Which fertilizer is best for cassava?

The best fertilizer for cassava is NPK 15-15-15 or NPK 12-12-17 + 2MgO. These balanced fertilizers give your cassava plants the right mix of Nitrogen, Phosphorus, and Potassium needed for strong stem growth and heavy root expansion.

Cassava needs high amounts of Potassium to transfer energy from its leaves down into the underground roots. Without enough Potassium, your cassava will grow tall stems with bushy leaves, but the underground roots will stay tiny and thin.

Recommended NPK Ratios for Cassava

NPK 15-15-15 provides an equal share of nutrients to support stem, leaf, and root growth in the early months. NPK 12-12-17 is rich in Potassium, making it ideal for the root swelling phase.

You should apply your first dose of NPK fertilizer 4 to 8 weeks after planting. This ensures the young root system is active enough to absorb the nutrients from the moist soil.

Organic Fertilizer Options for Cassava

Well-rotted poultry manure and cured cow dung make excellent organic fertilizers for cassava. Organic manure improves your soil structure, retains ground moisture, and feeds useful soil microbes.

Never apply fresh, raw animal manure directly to your stems because it creates excess heat that rots young plant roots. Always let manure decay completely into rich black compost before spreading it on your ridges.

Fertilizer Application Timing and Methods

Apply fertilizer when the soil is wet so the nutrients dissolve properly for the roots to drink. Never apply fertilizer on dry soil, as the chemicals will sit unused and burn the stems when rain falls later.

Dig a small ring 10cm away from the stem base, drop the fertilizer inside, and cover it back with soil. This ring method prevents wind and rain runoff from washing your expensive fertilizer away.

How many times can cassava be harvested in a year?

Cassava can be harvested only once per plant in its life cycle. When you uproot a cassava plant to collect its roots, the whole stand is removed, and you must plant new stem cuttings for the next harvest.

However, you can harvest cassava continuously throughout the year by practicing staggered planting. By planting different farm sections in different months, you create a continuous harvesting schedule that brings in weekly or monthly farm income.

Understanding the Single-Harvest Crop Cycle

Unlike crops like pepper or tomato that produce fruit over and over, cassava stores all its food in subterranean roots. Harvesting requires pulling the entire root cluster out of the ground.

Once uprooted, that single cassava stand cannot produce new roots. You must cut fresh stems from the harvested plant to start a new crop cycle on prepared ridges.

Staggered Planting for Year-Round Harvesting

Staggered planting means dividing your total land into smaller plots and planting them at different times. For instance, you can plant Plot A in March, Plot B in May, and Plot C in July.

When Plot A is ready for harvest next year, Plot B and Plot C will mature in line after it. This strategy keeps fresh cassava flowing to your buyers all year round while protecting you from sudden price drops.

Post-Harvest Stalk Management for Replanting

After harvesting your roots, save healthy, disease-free stems like Farmers Pride cassava stems for the next planting round. Cut the thick stems into 1-meter lengths and store them under cool shade.

Keep your stored stems standing upright in moist soil under a tree to keep them fresh. Good stem storage ensures high sprouting rates when you plant your next plot.

Can I plant cassava and yam together?

Yes, you can plant cassava and yam together on the same farm. Intercropping yam and cassava is a common practice among Nigerian farmers to maximize land use and harvest two major food crops from one field.

To succeed with this mix, you must plant your yam first and wait 4 to 8 weeks before introducing cassava stems. If you plant cassava first, its dense green leaves will shade out the young yam vines and stop them from growing properly.

Benefits of Intercropping Yam and Cassava

Combining yam and cassava reduces your risk of total crop loss from bad weather or pests. Yam is harvested early in the season, leaving the cassava to cover the field and use the remaining soil nutrients.

This combination also keeps weeds from filling your farm. The wide cassava canopy shields the ground, cutting down the money and time you spend on manual weeding.

Proper Spacing and Planting Sequence

Plant your yam seeds on high ridges spaced 1.5 meters apart to give the yam tubers plenty of room to expand. Wait for the yam vines to sprout and climb their stakes before planting cassava stem cuttings between the ridges.

Maintain a wide gap between plants so both crops get enough sunshine. Good spacing prevents the two plant root systems from fighting for space under the soil.

Managing Competition for Soil Nutrients

Yam and cassava are both heavy feeders that draw large amounts of nutrients from the ground. Planting them together without feeding the soil will leave you with tiny yam tubers and thin cassava roots.

Apply well-balanced fertilizer or organic manure 6 weeks after intercropping to feed both plants adequately. You can browse our wide range of farm inputs on the HTS Farms shop to find certified fertilizers and crop protectors for your farm.
