The Significance of Cassava in Agriculture
In the realm of global agriculture, cassava emerges as a cornerstone crop, particularly within Nigeria, which stands as a leading producer. With an anticipated production output of 106 million tonnes by 2030, the significance of cassava cannot be overstated. This is further underscored by the expected yield of 7.7 tonnes/ha and the projected cropped area reaching 9.6 million hectares. Despite these promising figures, it’s crucial to note a potential decline in cassava food supply per capita, from 267 Kcal/capita/day in 2014 to 239 Kcal/capita/day by 2030, signaling a need for strategic agronomic practices and storage solutions to counteract this trend.
- Global Importance:
-
- Nigeria’s Role: World’s largest producer with a forecasted output of 106 million tonnes by 2030.
- Yield and Cropped Area: Expected yield of 7.7 tonnes/ha over 9.6 million hectares.
- Food Supply Concern: Decline in per capita food supply, highlighting the importance of enhanced production and storage techniques.
Cassava’s versatility extends beyond mere subsistence farming, serving as both a subsistence and cash crop. Its introduction into Africa by Portuguese traders several centuries ago has culminated in its status as the most important tropical root crop, providing essential dietary energy for over 500 million people globally. Its rank as the fourth most crucial food crop in developing countries, after staples like rice, maize, and wheat, showcases its pivotal role in food security.
- Versatility and Usage:
-
- Subsistence and Cash Crop: A dual role that underscores its economic value.
- Historical Significance: Centuries of cultivation since its introduction by Portuguese traders.
- Global Staple: Essential dietary energy source for over 500 million people.
Moreover, cassava’s adaptability to harsh environments, including poor soil conditions and limited water resources, underscores its resilience. This characteristic, combined with its diverse applications ranging from food products to industrial uses like ethanol production, positions cassava as a critical crop in addressing food security and economic opportunities in tropical and subtropical regions.
- Resilience and Applications:
-
- Adaptability: Thrives in challenging environments, offering a reliable food source.

Effective Agronomic Practices
In Brazil, India, and Thailand, smallholder cassava farmers have showcased the potential of intensive farming practices, achieving remarkable yields of 25-40 tonnes per hectare. Similarly, adopting improved varieties and enhanced agronomic practices could elevate yields in Nigeria to 25 tonnes per hectare. This highlights the pivotal role of innovative agronomic strategies in optimizing cassava production. Key practices include:
- Soil Management:
-
- Transition to zero tillage to enhance root functionality and soil health.
- Maintain organic soil cover to conserve water, nutrients, and suppress weeds, thus fostering beneficial soil biota.
- Crop Management:
-
- Intercropping with early maturing crops to protect soil and limit weed growth.
- Adopt the ‘Save and Grow’ approach, focusing on soil structure preservation, organic matter maintenance, and a diverse crop range to mitigate pests and diseases.
- Fertilization and Planting Techniques:
-
- Apply 5-10 t/ha of animal manure along with 50-100 kg/ha of N and/or K2O.
- Optimal planting methods vary with the season; vertical or inclined planting is preferable during droughts, while ridge planting is advantageous in the rainy season.
These practices are instrumental in achieving high and sustainable cassava yields, underlining the importance of agronomic practices and crop management in enhancing cassava production and storage.

FAQs
What are the recommended agronomic practices for growing cassava?
To achieve the best yields in cassava farming, it is advised to plant cassava cuttings at intervals of 1 meter by 1 meter. An adequate nutrient supply is crucial, which can be maintained by applying fertilizers, with a preference for organic options such as farmyard manure. Four weeks after planting, it is beneficial to apply 250 grams of poultry manure per cassava plant.
What difficulties do cassava farmers encounter?
Cassava farmers often face several challenges including a lengthy period before the plants mature, variability in dry matter and starch content, high levels of cyanogenic compounds that can be toxic, poor cooking qualities, and susceptibility to diseases such as cassava bacterial blight and root rot, particularly in forested regions.
How can one achieve success in cultivating cassava?
For successful cassava cultivation, an optimal plant density is between 6,000 to 10,000 plants per hectare, which translates to a spacing of 1.5 x 1 meter or 1 x 1 meter for sole cultivation, and 2 x 2 meters when intercropping. It’s beneficial to grow cassava alongside other crops to enhance profitability and improve soil quality, with a recommended density of 2,500 plants per hectare for intercropping.
Which crop is most advantageous to grow with cassava?
When intercropping cassava, maize is a common and advantageous companion crop, particularly when cassava is the primary crop and maize is secondary. Intercropping cassava with maize or legumes has shown a biological advantage over growing these crops alone, as evidenced by (modified) Area × Time Equivalency Ratio (ATER) values exceeding one, indicating greater productivity.
