Cauliflower Farming in Kenya: A Profitable Niche Venture

Cauliflower is a highly nutritious vegetable that closely resembles cabbage due to its white curds. It is widely grown in areas such as Kiambu, Kakamega, and Taita Taveta, although it remains a niche crop due to its relatively low popularity in Kenya. Despite this, cauliflower farming can be profitable for farmers targeting high-end markets.


Popular Cauliflower Varieties in Kenya

Farmers in Kenya grow several varieties of cauliflower, each suited to specific growing conditions and market demands:

  • Cheddar AGM
  • Flame Star Hybrid
  • Graffiti AGM
  • Kibo Giant
  • Clapton
  • Italian Giant
  • Early Snowball
  • Fioretto 60

Ecological Conditions for Growing Cauliflower

For optimal growth, cauliflower requires the following conditions:

  • Soil: Fertile, well-drained soil with a pH of 6.0-6.5 and good moisture retention.
  • Altitude: 1,000-2,000m above sea level.
  • Rainfall: Minimum annual rainfall of 500mm.
  • Temperature: 12-28°C.
  • Drainage: Proper drainage is essential, as cauliflower is sensitive to waterlogging.

Propagation and Planting

Cauliflower is propagated by seeds, which are first raised in a nursery before being transplanted into the main field.

Steps for Propagation:

  1. Raise seedlings in a nursery for 3-4 weeks.
  2. Maintain a spacing of 45-60cm within rows and 60-75cm between rows in the nursery.

Transplanting:

  • Transplant seedlings once they reach the desired size and strength, typically after 3-4 weeks.

Fertilizer Application

Cauliflower is a heavy feeder and requires adequate potassium and nitrogen for optimal growth.

  1. At Planting: Apply 100kg of nitrogen, 100kg of P205, and 100kg of K20 per hectare.
  2. Topdressing:
    • Apply 20g of CAN when the plant reaches 20cm in height.
    • After 3 weeks, apply an additional 40g of CAN.

Weed Management

  • Importance: Keeping the farm weed-free is crucial to prevent competition for nutrients and water.
  • Method: Practice shallow cultivation to remove weeds and minimize soil disturbance.

Pests and Diseases Management

Common Pests:

  • Aphids
  • Cutworms
  • Diamondback moths

Control Measures:

  • Use recommended insecticides such as Polytron to manage pest infestations.

Common Diseases:

  • Ring Spot
  • Black Rot
  • Dry Rot
  • Bacterial Soft Rot
  • Yellowing Disease
  • Downy Mildew

Management Practices:

  • Rotate crops regularly to prevent disease buildup.
  • Maintain proper field hygiene.
  • Plant disease-resistant varieties recommended by experts.

Harvesting

Cauliflower matures in 3-5 months, depending on the variety and ecological conditions.

Harvesting Guidelines:

  • Cut the heads when fully developed, ensuring the leaves are still green.
  • Leave a set of leaves attached to protect the curds.

Yield: One hectare of cauliflower can produce 20-25 tons.


Market for Cauliflower in Kenya

Cauliflower is a niche crop with limited demand in the domestic market. The best opportunities lie in high-end markets, including:

  • High-end supermarkets
  • Grocery stores

Pricing: A kilogram of cauliflower can fetch up to Ksh 400 in these premium markets.


With proper management practices and strategic marketing, cauliflower farming in Kenya can be a profitable venture for farmers willing to cater to a niche but high-value market.
