About Cabbage farming in Kenya
Cabbage scientifically known as Brassica oleracea is a leafy vegetable widely grown in Kenya. Its popularity stems from its versatility in culinary use, high nutritional value, and relatively short growing cycle. The crop thrives in various regions of Kenya, such as Central Kenya, Rift Valley, and Western Kenya, where the climate is favorable. Cabbage grows best at altitudes ranging from 1,200 to 2,500 meters above sea level.
The crop requires a cool climate with temperatures between 15°C and 20°C. Higher temperatures may lead to bolting or reduced head quality. Well-drained loamy soils with a pH of 6.0 to 6.5 are ideal for cabbage. Acidic soils should be amended with lime before planting. Cabbage requires consistent moisture throughout its growth period. However, excessive rainfall can lead to waterlogging and diseases.
Hybrid Varieties (F1):
Gloria F1 – Known for uniform, dense heads and disease resistance.
Victoria F1 – A high-yielding, compact hybrid with good market appeal.
Amani F1 – Resilient in tropical climates, offering good size and quality.
Pruktor F1 – A premium hybrid with consistent performance and attractive heads.
Winner F1 – Renowned for early maturity and strong adaptability.
Kilimo F1 – Suited for tropical climates, often preferred for its robustness.
Open-Pollinated Varieties:
Sugarloaf – A classic, cone-shaped cabbage with a sweet taste.
Copenhagen Market – Compact and ideal for small-scale farmers; good storage.

Early Jersey Wakefield – Early-maturing, cone-shaped with tender leaves.
Charleston Wakefield – A larger version of the Jersey Wakefield, well-adapted to warmer climates.
Kiboko – Often grown in tropical regions, popular for its heat tolerance.

Central Kenya
Known for fertile soils and favorable climate, areas like Nyeri, Nyandarua , Murang'a and Kinangop lead in cabbage production.
Rift Valley
Nakuru and Eldoret are notable for large-scale cabbage farms.
Western Kenya
Counties like Kisii and Kakamega contribute significantly to cabbage farming.
Key Nutrients for Cabbages
Nitrogen (N) – Promotes leafy growth, essential during early growth stages.
Phosphorus (P) – Supports root development and early establishment.
Potassium (K) – Enhances head formation, disease resistance, and quality.
Secondary Nutrients:
Calcium (Ca) – Prevents disorders like tip burn.
Magnesium (Mg) – Supports photosynthesis.
Micronutrients:
Boron (B) – Prevents hollow stems and other deformities.
Molybdenum (Mo) – Helps in nitrogen utilization.
Recommended Fertilizer Types:
1. Organic Fertilizers:
Compost/Manure: Enriches soil with organic matter and slow-release nutrients.
Bone Meal: Provides phosphorus for root development.
Wood Ash: Supplies potassium.
2. Inorganic Fertilizers:
General Purpose NPK Fertilizers:
Use a balanced NPK ratio (e.g., 16:16:16) for early growth.
Transition to a higher potassium formulation (e.g., 10:10:20) during head formation.
Urea or Ammonium Sulfate: High in nitrogen; apply sparingly to avoid overgrowth or disease.
Calcium Nitrate: Supplies calcium and nitrogen for better head development.
Application Recommendations
Before Planting:
Test soil to determine nutrient needs.
Apply well-rotted compost or manure (3-5 tons per acre).
Add phosphorus and potassium fertilizers (e.g., DAP or TSP) to enrich the planting bed.
After Planting (Top-Dressing):
2-3 weeks after transplanting: Apply a nitrogen-rich fertilizer (e.g., urea or CAN).
Mid-Growth: Use a balanced NPK fertilizer to support leaf growth.
Head Formation Stage: Apply potassium-rich fertilizer to enhance quality.
Additional Tips:
Boron: Apply foliar sprays with boron (e.g., Borax) if deficiencies are noted.
Magnesium: Use Epsom salts for magnesium deficiency.
Frequency: Split fertilizer applications to avoid leaching and overfeeding.
Watering: Always water the plants after fertilizing to prevent root burn.
Drip Irrigation:
Efficient water use and minimized fungal disease risks.
Precision Farming
Use of technology like GPS and drones to optimize field management.
Organic Farming
Growing cabbages without synthetic inputs to cater to health-conscious consumers.
Tips for Successful Cabbage Farming
Soil Testing
Conduct regular soil tests to determine nutrient deficiencies.
Good Agricultural Practices (GAP)
Adhere to GAP to enhance yields and maintain environmental sustainability.
Market Research
Understand market trends and timing to maximize profits.
Post-Harvest Handling
Proper storage and transportation prevent losses and maintain quality.
Steps in Cabbage Farming
Land Preparation
Plow the land to a fine tilth to ensure good root penetration ,add organic manure or compost to improve soil fertility. Avoid planting cabbage in soils that previously hosted other brassica crops to minimize disease risks.
Seed Selection and Nursery Preparation
Use certified seeds from reputable suppliers. Prepare a nursery bed in a well-drained location. Sow seeds 1 cm deep and cover lightly with soil.Water regularly to maintain moisture but avoid overwatering.
Transplanting
Transplant seedlings when they are 4–6 weeks old and have 4–6 true leaves. Space plants 45 cm apart in rows spaced 60 cm apart to allow for good aeration and growth.
Crop Management
Ensure consistent watering, especially during dry spells. Weeding Keeps the field weed-free to reduce competition for nutrients.
Apply nitrogen-rich fertilizers during the vegetative stage and potassium-rich fertilizers during head formation.
Pest and Disease Management
Common pests include aphids, diamondback moths, and cabbage loopers. Use integrated pest management (IPM) methods such as natural predators and targeted pesticide application.
Diseases like black rot, clubroot, and powdery mildew are prevalent. Practice crop rotation and apply fungicides as needed.
6. Harvesting
Harvest cabbage heads when they are firm and fully formed, typically 75–120 days after transplanting, depending on the variety.
Economic Potential of Cabbage farming
Local Market
Cabbage is a staple vegetable with consistent demand in urban and rural areas.
Export Potential
Kenyan cabbage is exported to neighboring countries, such as Uganda and Tanzania, and the Middle East.
Value Addition
Processing cabbage into products like sauerkraut and pickles can boost profitability.
Challenges facing Cabbage Farming
Pests and Diseases
Heavy infestations can significantly reduce yields. Farmers must invest in pest control measures.
Unpredictable Weather
Climate change has led to erratic rainfall patterns, impacting crop production.
Market Fluctuations
Price volatility can affect profitability.
High Input Costs
Fertilizers, certified seeds, and pesticides can be expensive, especially for small-scale farmers.
