Sugarcane is a cash crop that has been grown in Kenya for many years. It is a tall perennial grass that is widely cultivated for its sweet juice, which is used to make sugar and other products. Sugarcane farming is an important economic activity in Kenya, with many small-scale farmers relying on the crop for their livelihoods.
Despite the importance of sugarcane farming in Kenya, many farmers still struggle to grow the crop successfully. This is due to various factors, including poor soil quality, inadequate irrigation, and pest infestations. However, with the right knowledge and techniques, it is possible to grow sugarcane successfully and profitably.
Climate Requirements
Growing sugarcane in Kenya requires a specific set of climate conditions. Sugarcane is a tropical crop and requires warm temperatures, high humidity, and well-distributed rainfall throughout the year. The following are the climate requirements for growing sugarcane in Kenya:
- Temperature: Sugarcane thrives in warm temperatures ranging from 20°C to 35°C. Temperatures below 20°C can slow down the growth of sugarcane, while temperatures above 35°C can damage the crop.
- Humidity: Sugarcane requires high humidity levels ranging from 70% to 85%. High humidity helps to reduce water loss through transpiration and ensures that the plant has sufficient moisture to grow.
- Rainfall: Sugarcane requires well-distributed rainfall throughout the year, with an average annual rainfall of 1,500mm to 2,000mm. The crop can tolerate drought conditions, but excessive rainfall can lead to waterlogging and root rot.
Kenya’s coastal region, Lake Victoria basin, and western parts of the country have suitable climate conditions for growing sugarcane. These regions have warm temperatures, high humidity, and well-distributed rainfall throughout the year.
However, sugarcane can also be grown in other parts of the country with the help of irrigation. Irrigation can supplement rainfall during dry spells and ensure that the crop has sufficient moisture to grow.

Soil Preparation
Before planting sugarcane in Kenya, it’s crucial to prepare the soil properly. This will ensure that the crop grows well and produces high yields. Here are some steps to follow:
- Clear the land of any weeds or debris. This can be done using a hoe or a plow.
- Test the soil to determine its pH level. Sugarcane grows best in soil with a pH between 5.5 and 6.5. If the soil is too acidic, add lime to raise the pH. If it’s too alkaline, add sulfur to lower the pH.
- Apply organic matter to the soil. This can be in the form of compost, manure, or any other organic material. Organic matter helps to improve soil structure and fertility.
- Till the soil to a depth of at least 20cm. This will help to loosen the soil and create a good seedbed for planting.
It’s important to note that the soil preparation process should be done well in advance of planting. This will give the soil enough time to settle and stabilize before planting begins. Additionally, it’s recommended to plant sugarcane during the rainy season when the soil is moist and easier to work with.
Planting
Planting sugarcane in Kenya requires careful consideration of the soil and climate conditions. The ideal time to plant sugarcane is at the beginning of the rainy season, when the soil is moist enough to support growth. Sugarcane can be planted using two methods: stem cuttings or seedlings.
Stem cuttings: This is the most common method used in Kenya. Cuttings are taken from mature sugarcane plants and planted in furrows, with each cutting placed about 20cm apart. The cuttings should be planted at a depth of about 5-10cm, with the buds facing upwards. The furrows should be spaced about 1m apart to allow for easy access during weeding and harvesting.
Seedlings: This method involves planting sugarcane seedlings that have been grown in a nursery. The seedlings are transplanted into the field at a spacing of about 20cm apart. This method is more expensive than stem cuttings and requires more labor, but it results in a higher yield and better quality sugarcane.
Before planting, it is important to prepare the soil by plowing and harrowing to a depth of about 20cm. This helps to loosen the soil and create a good seedbed for the sugarcane. The soil should also be tested for pH and nutrient levels, and any necessary amendments should be made.
Once the sugarcane is planted, it should be watered regularly to keep the soil moist. Weeds should be controlled by hand weeding or using herbicides, and pests and diseases should be monitored and treated as necessary. With proper planting and care, sugarcane can be a profitable crop for farmers in Kenya.
Fertilization
Fertilization is a crucial aspect of sugarcane farming in Kenya. It involves the application of nutrients to the soil to improve crop yield and quality. Sugarcane requires a balanced supply of nutrients to grow well, and farmers need to ensure that they apply the right fertilizers at the right time to achieve optimal results.
Before planting, farmers should conduct soil tests to determine the nutrient content and pH level of the soil. This will help them to choose the appropriate fertilizers and application rates. In general, sugarcane requires nitrogen, phosphorus, and potassium, as well as other micronutrients such as magnesium, sulfur, and zinc.
During the first six months of growth, sugarcane requires high levels of nitrogen to support its rapid growth. Farmers should apply nitrogen fertilizers at a rate of 100-150 kg/ha at planting and then top-dress with an additional 100-150 kg/ha of nitrogen after 60-90 days. Phosphorus and potassium should also be applied at planting, with rates of 60-80 kg/ha and 80-100 kg/ha, respectively.
After the first six months, sugarcane growth slows down, and the crop requires less nitrogen. Farmers should reduce the nitrogen application rate to 50-100 kg/ha during the second year of growth. In the third year, nitrogen application can be further reduced to 30-50 kg/ha.
In addition to chemical fertilizers, farmers can also apply organic fertilizers such as manure, compost, and green manure. Organic fertilizers can improve soil fertility, increase soil organic matter, and promote a healthy soil ecosystem. However, farmers should be careful not to over-apply organic fertilizers, as this can lead to nutrient imbalances and environmental pollution.
To summarize, fertilization is a critical component of sugarcane farming in Kenya. Farmers should conduct soil tests, choose appropriate fertilizers, and apply them at the right time and rate to achieve optimal crop yield and quality. By following these guidelines, farmers can improve their sugarcane production and contribute to the growth of the Kenyan agriculture sector.
Irrigation
Water is a crucial factor in sugarcane growth and development. In Kenya, sugarcane is mainly grown in areas that receive low and erratic rainfall. Therefore, it is essential to have an effective irrigation system to ensure adequate water supply to the crop.
The following are some of the irrigation methods that can be used for sugarcane farming in Kenya:
- Drip Irrigation: This method involves the use of a network of pipes and emitters to supply water directly to the roots of the plants. It is a very efficient method that saves water and reduces weed growth.
- Sprinkler Irrigation: This method involves the use of sprinklers to distribute water over the crop. It is a suitable method for large-scale sugarcane farming.
- Flood Irrigation: This method involves the flooding of the sugarcane fields with water. It is a traditional method that is not very efficient and can lead to waterlogging and soil erosion.
It is important to note that sugarcane requires a lot of water, especially during the first six months of growth. Therefore, it is essential to ensure that the irrigation system is efficient and provides adequate water supply to the crop.
In addition to irrigation, it is also important to ensure that the soil is well-drained to prevent waterlogging, which can lead to stunted growth and reduced yields.
Weed Control
Weed control is an essential part of growing sugarcane in Kenya. Weeds can compete with sugarcane for nutrients, water, and sunlight, reducing the yield and quality of the crop. Here are some effective ways to control weeds in sugarcane fields:
- Cultural control: This involves the use of practices such as crop rotation, intercropping, and cover cropping to suppress weeds. For example, planting legumes as cover crops can help to fix nitrogen in the soil and reduce weed growth.
- Mechanical control: This involves the use of tools such as hoes, cultivators, and weeders to physically remove weeds from the field. This method is labor-intensive but can be effective in small-scale farming.
- Chemical control: This involves the use of herbicides to kill weeds. Herbicides should be used with caution and according to the manufacturer’s instructions to avoid harming the sugarcane crop and the environment.
It is important to note that weed control should be integrated with other pest management practices to ensure the sustainability of sugarcane farming in Kenya. Farmers should also practice good field hygiene by removing weed debris and other crop residues to reduce the buildup of pests and diseases.
Pest and Disease Management
One of the biggest challenges in growing sugarcane is managing pests and diseases. Here are some tips for managing these issues:
- Integrated Pest Management (IPM): This approach involves using a combination of cultural, biological, and chemical control methods to manage pests. IPM techniques include crop rotation, intercropping, natural predators, and targeted pesticide use.
- Fungal Diseases: Sugarcane is susceptible to a number of fungal diseases, including smut, rust, and leaf blight. To manage these diseases, it is important to plant disease-resistant varieties, maintain proper spacing between plants, and apply fungicides as needed.
- Insect Pests: Sugarcane is also vulnerable to a variety of insect pests, including the sugarcane borer, the sugarcane aphid, and the sugarcane weevil. To manage these pests, it is important to monitor crops regularly, use insect-resistant varieties, and apply insecticides as needed.
- Nematodes: Nematodes are tiny worms that can cause significant damage to sugarcane roots. To manage nematodes, it is important to plant resistant varieties, rotate crops, and use nematicides as needed.
By following these tips and regularly monitoring crops for signs of pests and diseases, sugarcane farmers in Kenya can minimize losses and maximize yields.
Harvesting and Processing
Once your sugarcane is fully matured, it is time to harvest it. Sugarcane is typically harvested by hand, using a machete or other sharp tool to cut the stalks at the base. It is important to cut the stalks as close to the ground as possible to ensure that you get the maximum yield from each plant.
After harvesting, the sugarcane needs to be processed quickly to prevent deterioration. The first step in processing is to remove the leaves and outer layer of the stalks. This can be done manually or with a machine. Once the stalks are stripped, they are ready to be crushed to extract the juice.
There are a few different methods for crushing sugarcane. One traditional method is to use a wooden press, which is operated by hand or with the help of animals. Another option is to use a mechanical press, which can crush large quantities of sugarcane quickly and efficiently.
Once the juice has been extracted, it needs to be boiled to remove impurities and reduce the water content. This is typically done in large vats or pans over an open flame. The juice is stirred constantly to prevent burning and ensure even heating.
After boiling, the juice is left to cool and settle. The solids that settle to the bottom are called bagasse and can be used as fuel or animal feed. The clear liquid that remains is then further processed to produce sugar or other sugarcane products.
Overall, harvesting and processing sugarcane requires careful attention to detail and a lot of hard work. However, with the right techniques and equipment, it is possible to produce high-quality sugarcane products that can be sold for a profit.
Marketing and Sales
Once your sugarcane is ready for harvest, it’s time to think about marketing and sales. Here are a few tips to help you sell your sugarcane:
- Identify potential buyers: Research potential buyers in your area, including local markets, juice vendors, and sugar factories.
- Pricing: Determine a fair price for your sugarcane based on the prevailing market rates and your production costs.
- Packaging: Package your sugarcane in a way that makes it easy to transport and sell. Consider using bags or crates.
- Marketing: Use social media and other marketing channels to promote your sugarcane. Highlight the benefits of sugarcane and how it can be used in different ways.
It’s important to build relationships with your buyers to ensure repeat business. Provide high-quality sugarcane and excellent customer service to keep your buyers coming back.
