The Ultimate Guide to Cassava Farming in Kenya

Cassava Farming in Kenya

Cassava, also known as Manihot esculenta, is a versatile and resilient root crop that has become a staple food for millions of people across the globe, particularly in tropical and subtropical regions. Cassava farming in Kenya plays a crucial role in both food security and economic development. As a drought-tolerant crop, it provides a reliable source of carbohydrates, especially in areas prone to erratic rainfall. Beyond its nutritional value, cassava holds significant economic potential due to its adaptability, low input requirements, and diverse uses, ranging from food products to industrial applications.

Importance and Nutritional Value

Cassava is highly valued for its high carbohydrate content, making it an essential energy source in many households. The tuber is rich in starch, which can be processed into various products such as flour, gari, and starch for industrial uses. In addition to the tuber, cassava leaves are consumed as a vegetable in many parts of Africa, offering a good source of protein, vitamins, and minerals, including vitamin C, iron, and calcium.

Economic Potential

Economically, cassava is a key crop for smallholder farmers in Kenya, providing both food and income. The crop’s ability to thrive in marginal soils with minimal inputs makes it an attractive option for farmers seeking to diversify their crops and reduce the risks associated with Cassava farming in Kenya in arid and semi-arid regions. With the growing demand for cassava products locally and internationally, there are ample opportunities for farmers and agripreneurs to capitalize on this crop through value addition and marketing.

Cassava’s Role in Kenyan Agriculture and Food Security

In the context of Kenyan agriculture, cassava serves as a crucial buffer against food insecurity. Its resilience in the face of drought and poor soil conditions ensures that it can be grown in areas where other crops may fail. As a result, cassava contributes significantly to the food security of vulnerable populations, particularly in arid and semi-arid lands (ASALs) where other staple crops like maize and beans struggle to survive.

Moreover, the crop’s role in food security extends beyond the household level. Nationally, cassava is increasingly recognized as a strategic crop that can help reduce the country’s dependence on maize, especially during periods of drought or when maize yields are compromised. By promoting cassava farming, Kenya can enhance its food sovereignty and ensure a more stable food supply for its growing population.

Cassava Crop Profile

Botanical Classification and Origin

Cassava (Manihot esculenta) belongs to the family Euphorbiaceae, which comprises over 200 genera and about 6,000 species. It is believed to have originated from South America, specifically in the Amazon Basin, where it has been cultivated for thousands of years. The crop was introduced to Africa by Portuguese traders in the 16th century and has since spread across the continent, becoming a staple food in many countries, including Kenya.

Morphological Characteristics of the Cassava Plant

Cassava is a perennial woody shrub that typically grows to a height of 1 to 3 meters. The plant has a robust root system, with tuberous roots that are rich in starch and serve as the primary source of food. The stems are slender and can be either erect or trailing, depending on the variety. Cassava leaves are palmately compound, with 5 to 9 lobes, and can vary in color from green to purple.

The plant’s flowers are small and inconspicuous, typically appearing in clusters at the axils of the leaves. Cassava does not rely heavily on seeds for propagation; instead, it is predominantly propagated through stem cuttings. This method ensures that the genetic characteristics of the parent plant are preserved in the new generation.

Types of Cassava Varieties: Traditional and Improved

Cassava varieties in Kenya can be broadly classified into two categories: traditional and improved. Traditional varieties are those that have been grown by farmers for generations. These varieties are well adapted to local conditions and are often preferred for their taste and cooking qualities. However, they may be susceptible to diseases and pests, and their yields can be lower compared to improved varieties.

Improved varieties, on the other hand, are the result of breeding programs aimed at enhancing specific traits such as yield, disease resistance, and drought tolerance. These varieties have been developed by research institutions and are designed to address the challenges faced by cassava farmers, particularly in regions with high disease pressure or challenging environmental conditions. Improved varieties often outperform traditional ones in terms of yield and resilience, making them a valuable option for farmers seeking to increase productivity.

Adaptability: Areas in Kenya Where Cassava Thrives

Cassava is highly adaptable to a range of environmental conditions, making it one of the most widely cultivated crops in Kenya. The crop thrives in warm climates with moderate rainfall and can tolerate poor soils that are low in fertility. This adaptability allows cassava to be grown in diverse regions across Kenya, including the coastal areas, Western Kenya, and the arid and semi-arid lands (ASALs) of Eastern Kenya.

Several factors contribute to the success of cassava in these areas:

• Soil Type: Cassava prefers well-drained sandy loam soils but can also grow in clay soils as long as they are not waterlogged. The crop’s ability to grow in marginal soils makes it suitable for regions where other staple crops struggle.
• Climate: Cassava is a tropical crop that requires warm temperatures for optimal growth. It can thrive in areas with temperatures ranging from 18°C to 25°C, making it well-suited to Kenya’s varied climatic zones.
• Water Availability: While cassava is drought-tolerant, it performs best with consistent moisture during the early stages of growth. This makes it ideal for regions with moderate rainfall or where irrigation is available.

Nutritional Value of Cassava Roots and Leaves

Cassava is a vital source of energy, particularly in regions where food security is a concern. The roots are rich in carbohydrates, primarily in the form of starch, which constitutes about 25-30% of the fresh root weight. This makes cassava an excellent energy source, especially in diets where other carbohydrate-rich foods like maize or rice are scarce.

The nutritional profile of cassava roots includes:

• Energy: Approximately 160 calories per 100 grams of fresh root.
• Carbohydrates: Cassava roots are composed mainly of carbohydrates (about 38% of the root weight), which are crucial for energy.
• Fibre: The roots contain a moderate amount of dietary fibre, which aids in digestion.
• Vitamins and Minerals: Cassava roots are low in protein and fat but contain small amounts of vitamins and minerals such as vitamin C, calcium, and potassium.

Cassava leaves are also consumed in many parts of Africa and are highly nutritious. They are a good source of:

• Protein: Cassava leaves contain up to 25% protein, making them a valuable supplement to the predominantly carbohydrate-rich diet in cassava-growing regions.
• Vitamins: The leaves are rich in vitamins A and C, which are essential for immune function and skin health.
• Minerals: Cassava leaves provide important minerals, including iron, calcium, and magnesium, which contribute to overall health and well-being.

The combination of energy-rich roots and protein-packed leaves makes cassava a unique crop that can address multiple nutritional needs, especially in regions with limited access to diverse food sources.

How to Plant Cassava in Kenya

Land Preparation: Site Selection, Clearing, Ploughing, and Ridging

Ploughing

After clearing, the next step is ploughing the land. Ploughing turns over the soil, breaking up clumps and improving soil aeration. This process also helps to bury any weed seeds and organic matter, which will decompose and enrich the soil. In regions where the soil is compacted or heavy, deep ploughing is recommended to ensure that the cassava roots can penetrate the soil easily.

Ridging

Finally, ridging is done to create raised beds or mounds where the cassava will be planted. Ridging improves drainage and allows for better root development. It also makes it easier to harvest the tubers, as they tend to grow within the mounds. The ridges should be spaced about 1 metre apart to provide sufficient room for the cassava plants to grow.

Propagation: Stem Cuttings, Planting Methods, and Spacing

Cassava is propagated through stem cuttings rather than seeds. This method ensures that the new plants maintain the characteristics of the parent plant, including yield potential, disease resistance, and maturity period.

Stem Cuttings

Select healthy, disease-free stems from mature cassava plants that are 8 to 12 months old. The ideal cuttings are about 20 to 25 centimetres long and should have 5 to 7 nodes. These nodes are crucial, as they are the points from which roots and shoots will emerge once the cuttings are planted.

Planting Methods

There are two primary methods for planting cassava cuttings: horizontal and vertical. In the horizontal method, the cutting is laid flat in a shallow trench and covered with soil. This method encourages the development of more roots and tubers, as multiple nodes are in contact with the soil. The vertical method involves inserting the cutting into the soil at a 45-degree angle, leaving one or two nodes above the surface. This method is commonly used in areas where soil moisture is adequate, as it reduces the risk of rot and improves plant establishment.

Spacing

Proper spacing is vital for ensuring optimal growth and yield. The standard spacing for cassava plants is 1 metre by 1 metre, resulting in approximately 10,000 plants per hectare. However, the spacing can be adjusted based on the variety being planted, soil fertility, and the intended use of the crop (e.g., if intercropping is planned). Adequate spacing prevents overcrowding, which can lead to competition for resources and an increased risk of disease.

Minimal Care Requirements: Low Input Nature of Cassava Cultivation

One of the most appealing aspects of cassava cultivation is its low input requirements. Cassava is a hardy crop that can thrive with minimal care, making it an ideal choice for farmers with limited resources.

Drought Tolerance

Cassava is exceptionally drought-tolerant, capable of surviving prolonged dry spells once established. This characteristic makes it a reliable food source in arid and semi-arid regions, where other crops may fail due to lack of water. While cassava can tolerate drought, it benefits from regular watering during the initial stages of growth and in regions where rainfall is unpredictable.

Pest and Disease Resistance

Traditional cassava varieties are known for their resistance to many common pests and diseases. However, this resistance can vary depending on the variety and local conditions. Improved varieties have been developed with enhanced resistance to significant diseases like cassava mosaic disease (CMD) and cassava brown streak disease (CBSD), which are prevalent in Kenya. Regular monitoring and early intervention can help manage any emerging pest or disease issues.

Low Fertiliser Requirements

Although cassava can grow in poor soils, applying fertiliser can significantly boost yields, especially in nutrient-depleted soils. Organic fertilisers, such as compost or manure, are recommended to improve soil structure and fertility. Inorganic fertilisers can also be used, with a focus on nitrogen, phosphorus, and potassium (NPK). However, care should be taken not to over-fertilise, as this can lead to excessive vegetative growth at the expense of root development.

Improved Varieties: High-Yielding, Early Maturing, and Disease-Resistant Cassava Varieties Available in Kenya

In recent years, there has been a concerted effort to develop and promote improved cassava varieties in Kenya. These varieties have been bred to address specific challenges faced by farmers, such as low yields, disease susceptibility, and long maturity periods.

Overview of Cassava Improvement Programs in Kenya

Several institutions have been at the forefront of cassava improvement in Kenya, including the Kenya Agricultural and Livestock Research Organization (KALRO) and the International Institute of Tropical Agriculture (IITA). These organisations have collaborated on breeding programs to develop cassava varieties that are well-suited to Kenya’s diverse agro-ecological zones.

Key Institutions Involved:

• Kenya Agricultural and Livestock Research Organization (KALRO): KALRO has played a pivotal role in cassava research and development in Kenya. The organisation has developed several improved varieties that are high-yielding, early maturing, and resistant to diseases such as CMD and CBSD.
• International Institute of Tropical Agriculture (IITA): IITA has been instrumental in introducing and promoting improved cassava varieties across Africa, including Kenya. Their research focuses on developing varieties that can withstand the challenges posed by climate change and evolving pest and disease pressures.

Profiles of Improved Cassava Varieties:

• Variety Name: For example, ‘Kibandameno,’ ‘Shibe,’ or ‘Tajirika.’
• Key Characteristics: Each variety is bred for specific traits, such as high yield (up to 30 tonnes per hectare), early maturity (as short as 6 to 9 months), and resistance to CMD and CBSD.
• Adaptation to Different Agro-Ecological Zones: Improved varieties are adapted to thrive in various agro-ecological zones in Kenya, from the humid coastal regions to the dry ASALs.
• Planting and Harvesting Recommendations: Guidance is provided on the optimal planting and harvesting times to maximise yield and quality.
• Potential Market Outlets: Improved varieties offer excellent opportunities for both local and export markets, with the potential for value addition through processing into flour, starch, or other products.

Crop Management: Weeding, Fertilisation, Irrigation, and Pest/Disease Control

Effective crop management is crucial to achieving high yields and maintaining the health of cassava plants throughout the growing season. This section outlines best practices for managing weeds, fertilisation, irrigation, and controlling pests and diseases in cassava farming in Kenya.

Weeding

Weeds compete with cassava plants for nutrients, water, and sunlight, which can significantly reduce yields. The first 3 to 4 months after planting are critical for weed control, as this is when cassava plants are most vulnerable to competition. Weeding should be done regularly during this period to keep the field clean. Manual weeding using a hoe is common, but for larger farms, mechanised weeding or the use of herbicides may be more practical.

For farmers using herbicides, it’s important to choose selective herbicides that target weeds without harming the cassava plants. Additionally, intercropping cassava with other crops like legumes can help suppress weeds naturally, reducing the need for frequent weeding.

Fertilisation

Although cassava is known for its ability to grow in poor soils, applying fertilisers can greatly enhance root development and increase yields. The type and amount of fertiliser required depend on the soil’s nutrient status, which can be determined through soil testing. In general, cassava benefits from a balanced application of nitrogen (N), phosphorus (P), and potassium (K).

• Nitrogen (N): Promotes healthy leaf and stem growth, which supports photosynthesis and overall plant vigour.
• Phosphorus (P): Essential for root development and energy transfer within the plant, phosphorus helps in the formation of large, healthy tubers.
• Potassium (K): Enhances the plant’s resistance to diseases and improves the quality of the tubers by increasing their starch content.

A typical fertilisation schedule might involve applying a basal dose of NPK fertiliser at planting, followed by top-dressing with nitrogen-rich fertilisers 6 to 8 weeks after planting. Organic fertilisers such as compost or manure can also be incorporated into the soil before planting to improve soil structure and fertility.

Irrigation

Cassava is drought-tolerant but responds well to adequate moisture, particularly during the early stages of growth. In regions with inconsistent rainfall, supplementary irrigation may be necessary to ensure that the plants establish well and grow vigorously. Drip irrigation is an efficient method for delivering water directly to the root zone, minimising water waste and reducing the risk of waterlogging.

During the dry season, irrigation should be applied at intervals that prevent the soil from drying out completely. However, care must be taken not to over-irrigate, as excessive moisture can lead to root rot and other water-related issues.

Pest and Disease Control:

Cassava is relatively resilient to pests and diseases, but some issues can still arise, particularly in areas where improved varieties are not used. The most common pests include cassava mealybugs, cassava green mites, and whiteflies. These pests can cause significant damage by feeding on the plant’s sap, leading to reduced vigour and lower yields.

To manage pest infestations, it is important to regularly monitor the crop and take early action if pests are detected. Biological control methods, such as introducing natural predators like ladybirds and parasitic wasps, can be effective in controlling mealybugs and mites. In cases of severe infestations, insecticides may be necessary, but these should be used sparingly to avoid harming beneficial insects and the environment.

Diseases like cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are also significant threats to cassava production in Kenya. These viral diseases can cause severe yield losses if not managed properly. The most effective way to control these diseases is to plant disease-resistant varieties developed by research institutions such as KALRO and IITA. Additionally, farmers should practice crop rotation and avoid planting cassava in fields where these diseases have previously occurred.

Regular field inspections and the removal of infected plants can also help prevent the spread of disease. It is advisable to destroy any diseased plant material by burning, as this prevents the pathogens from spreading to healthy plants.

Intercropping and Crop Rotation

Intercropping

Intercropping cassava with other crops is a common practice in Kenya and offers several benefits, including improved soil fertility, better weed control, and diversified income for farmers. Common intercrops with cassava include legumes (such as beans, cowpeas, and groundnuts), maize, and vegetables. Legumes are particularly beneficial because they fix nitrogen in the soil, enhancing soil fertility for the cassava plants.

When planning an intercrop, it is important to consider the growth habits of the companion crops. For example, maize, which grows tall, can provide shade for young cassava plants, reducing the impact of intense sunlight and conserving soil moisture. However, care must be taken not to overcrowd the field, as this can lead to competition for resources.

Crop Rotation

Crop rotation is another effective strategy for maintaining soil health and reducing the build-up of pests and diseases. Rotating cassava with other crops, such as cereals or legumes, helps break the life cycles of pests and diseases that might otherwise thrive in continuous cassava cultivation.

For instance, after harvesting cassava, planting a cereal crop like maize or sorghum in the following season can help deplete the soil of any pests or diseases that specifically target cassava. This practice also helps to balance nutrient levels in the soil, as different crops have varying nutrient requirements.

Harvesting Techniques and Timing

Harvesting cassava at the right time is crucial to ensuring the best quality and yield. The maturity period for cassava varies depending on the variety and growing conditions but generally ranges from 8 to 18 months.

Harvesting Timing

The timing of the harvest depends on several factors, including the intended use of the cassava. For fresh consumption, cassava should be harvested when the roots are fully mature, usually between 9 to 12 months after planting. At this stage, the roots have accumulated the maximum starch content, making them ideal for processing into products like gari, flour, or chips.

For industrial purposes, such as starch extraction, cassava can be left in the ground longer, up to 18 months, to increase the starch yield. However, care must be taken to harvest before the roots become fibrous or woody, which can occur if they are left too long in the soil.

Harvesting Techniques

Cassava harvesting can be labour-intensive, as the roots grow deep in the soil. In smallholder farms, harvesting is typically done manually using a hoe or digging stick. The process involves loosening the soil around the base of the plant and carefully pulling up the roots to avoid damaging them.

For larger farms, mechanised harvesting may be employed to reduce labour costs and speed up the process. Mechanical harvesters are designed to lift the entire plant, including the roots, from the soil, making it easier to collect and transport the tubers.

After harvesting, the roots should be processed or consumed as soon as possible, as they have a high moisture content and are prone to spoilage if left exposed for too long. If immediate processing is not possible, the roots can be stored in a cool, dry place for a short period or preserved through traditional methods such as drying or fermentation.

Post-Harvest Handling and Storage:

Proper post-harvest handling is essential to maintain the quality and shelf life of cassava roots. After harvesting, the roots should be cleaned to remove any soil or debris. If the cassava is to be sold fresh, it should be transported to the market quickly to avoid deterioration.

For longer storage, cassava roots can be processed into dried chips or flour, which have a much longer shelf life. Drying can be done naturally in the sun or using mechanical dryers, depending on the resources available. Once dried, the cassava products should be stored in a cool, dry place, ideally in airtight containers to prevent moisture absorption and contamination.

Cassava Production and Marketing in Kenya

Understanding the economics of cassava farming in Kenya is essential for making informed decisions about investment, production, and marketing. This section delves into the financial aspects of cassava cultivation, including planting and harvest density, the cost of production, income potential, and the marketing channels available for cassava products in Kenya. Additionally, it highlights the challenges and opportunities in the cassava market, as well as government policies and support mechanisms for cassava farmers.

Planting and Harvest Density

Optimal Planting Density:

The planting density of cassava significantly influences both yield and root quality. The optimal planting density for cassava ranges from 10,000 to 15,000 plants per hectare, depending on the variety and local conditions. A common spacing recommendation is 1 metre by 1 metre, which allows sufficient room for the roots to develop fully without overcrowding.

Higher densities can lead to smaller roots due to competition for nutrients and moisture, while lower densities may reduce total yield per hectare. It is, therefore, crucial to strike a balance to achieve the best possible yield and root size.

Harvest Density:

The timing and method of harvest also impact the economics of cassava farming in Kenya. Harvesting all plants at once is typical, but staggered harvesting, where only mature roots are removed while leaving others to continue growing, can be beneficial in managing market supply and demand. This approach allows farmers to maximise income by selling cassava when prices are favourable while ensuring continuous production.

Cost of Cassava Production

Inputs and Labour

The cost of cassava production varies depending on factors such as farm size, input use, and labour availability. Key inputs include planting materials (stem cuttings), fertilisers, herbicides, and labour for land preparation, planting, weeding, and harvesting.

On average, the cost of producing cassava on a small to medium-scale farm in Kenya ranges from KSh 50,000 to KSh 100,000 per hectare. Labour accounts for a significant portion of this cost, particularly in manual operations such as weeding and harvesting. However, the low-input nature of cassava cultivation means that farmers can achieve good returns even with modest investments in inputs.

Price of Cassava in Kenya: Cassava Yield Per Acre in Kenya

Cassava farming in Kenya can be highly profitable, especially when market conditions are favourable. Depending on the variety, soil fertility, and management practices, yields can range from 10 to 30 tonnes per hectare. At current market prices, gross income from cassava farming can range from KSh 200,000 to KSh 600,000 per hectare, providing a solid return on investment.

While biological control is preferred, chemical pesticides are sometimes necessary to manage severe pest infestations. Research is ongoing to develop safer and more effective pesticides that can be used in cassava farming in Kenya. The aim is to provide farmers with options that minimise environmental impact while effectively controlling pests.

Integrated Pest Management (IPM)

IPM combines multiple strategies, including biological control, chemical control, and cultural practices, to manage pests in a holistic and sustainable manner. Research on IPM for cassava is helping farmers adopt practices that reduce the reliance on chemical pesticides and promote long-term pest management solutions.

Disease Management

In addition to breeding disease-resistant varieties, research is also focused on developing practices that help manage and control diseases in cassava fields. This includes the use of clean planting material, crop rotation, and sanitation practices to prevent the spread of diseases. Extension services play a key role in disseminating this knowledge to farmers.

Post-Harvest Technologies and Value Addition Research

Post-harvest losses are a major challenge in cassava farming in Kenya, and research is being conducted to develop technologies that reduce these losses and enhance the value of cassava products.

Storage Techniques

Cassava roots are highly perishable and begin to deteriorate soon after harvest. Research is focused on developing storage techniques that extend the shelf life of cassava roots, such as cold storage, waxing, and the use of preservatives. These techniques help reduce post-harvest losses and allow farmers to store cassava for longer periods, thus improving market flexibility.

Processing Technologies

Research on cassava processing is aimed at improving the efficiency and quality of value-added products. This includes the development of mechanised processing equipment that can handle large volumes of cassava, as well as technologies that improve the extraction of starch and other products. By enhancing processing efficiency, these technologies help increase the profitability of cassava farming in Kenya.

Value Addition Research

Value addition is a key area of research, with efforts focused on developing new cassava-based products that cater to emerging market trends. This includes research on the use of cassava in gluten-free products, biofuels, and industrial applications. The aim is to diversify the range of products that can be derived from cassava and create new market opportunities for farmers and processors.

Role of Research Institutions and Extension Services

Research institutions and extension services are critical in advancing cassava farming in Kenya. They play a central role in developing new technologies, disseminating knowledge, and supporting farmers in adopting best practices.

Research Institutions

Institutions like KALRO and IITA are at the forefront of cassava research in Kenya. These institutions conduct breeding programmes, develop pest and disease management strategies, and explore new uses for cassava. Their work is essential in ensuring that Kenyan cassava farmers have access to the latest innovations and technologies.

Extension Services

Extension services act as a bridge between research institutions and farmers. They provide training, distribute improved planting materials, and offer advice on best practices in cassava cultivation and processing. By working closely with farmers, extension officers help ensure that research findings are translated into practical benefits on the ground.

Public-Private Partnerships

Collaboration between the public and private sectors is also vital for the advancement of cassava farming. Public-private partnerships facilitate the scaling up of research innovations, the distribution of improved varieties, and the development of market linkages. These partnerships help create a more dynamic and sustainable cassava sector in Kenya.
