Varieties of Beans Grown in Kenya
Several varieties of beans are grown in Kenya, each with distinct characteristics suited to various climates and consumer preferences. Some of the common varieties include:
- Wairimu
- Rose Coco
- Mwezi Moja
- Mwitemania

Ecological Requirements for Growing Beans
To grow beans successfully in Kenya, certain environmental factors need to be considered:
- Annual Rainfall: 800-2000 mm
- Soil: Well-drained soils with a pH of 6.5-7.5, rich in organic matter.
- Temperature: Beans thrive in temperatures ranging from 15°C to 33°C.
- Altitude: Beans grow best at altitudes between 1,000 and 2,100 meters above sea level.
Planting Beans
Beans should be planted at the onset of rains when the soil is moist. Follow these guidelines for successful planting:
- Land Preparation: Prepare the land thoroughly before planting.
- Propagation: Beans are propagated by seeds, which should be sown directly in the ground.
- Spacing: Recommended spacing is 40 cm by 15 cm, with 2 seeds per hole at a depth of about 2 inches.
- Intercropping: Beans can be intercropped with other crops, such as maize, for better growth and higher yields.
- Germination: Beans typically take about 7 days to germinate, depending on the variety.
Fertilizer Application
Beans need adequate nutrients for optimal growth:
- Basal Fertilizer: Apply phosphorus-rich fertilizers during planting.
- Topdressing: Use CAN (Calcium Ammonium Nitrate) for topdressing, which should be applied 4 weeks after germination. Other basal fertilizers can also be used for additional topdressing.
Pests and Diseases
Beans are susceptible to various pests and diseases, which can negatively impact yields. Common pests include:
- Aphids
- Red Spider Mites
- Alonze Soec
- Leaf Miners
- Pod Borers
- Whiteflies
Common diseases include:
- Downy Mildew
- Bean Rust
- Anthracnose
- Bacterial Blight
- Fusarium Wilt
Management:
- Use recommended pesticides and fungicides like Pentagon, Green Cop, and Ransom.
- Practice proper field hygiene to prevent the spread of pests and diseases.
Harvesting
Beans typically take between 70 to 120 days to mature, depending on the variety. Beans are ready for harvesting when the pods have matured and turned yellow. After harvesting, ensure that the beans are properly dried before storage.

Conclusion
Beans farming in Kenya is a lucrative and essential part of the agricultural sector. With proper planting techniques, pest management, and access to markets, farmers can enjoy good returns from beans production. By meeting the ecological requirements and adopting modern farming practices, Kenyan farmers can increase their yields and contribute to the country’s food security.
