Cabbage Farming Program, Cabbage is one of Kenya’s most important commercial vegetables due to its high demand, good market price, and adaptability across regions. However, producing uniform, firm, and market-ready heads requires a structured farming program. This guide outlines a complete cabbage production schedule to help farmers achieve consistent, profitable results.

1. Land Preparation

Soil Requirements

• Well-drained loam soil
• pH: 6.0–6.5
• Rich in organic matter

Preparation Steps

For Cabbage Farming Program to be succefull we begin by ploughing the land deeply to break compacted layers. Afterward, incorporate 8–12 tons of well-decomposed manure per acre to improve soil fertility and water-holding capacity. In addition, form raised beds in areas prone to waterlogging to minimize root diseases.

2. Seed Selection & Nursery Management

Recommended Varieties

Choose high-quality hybrid or open-pollinated varieties such as:

• Glory F1
• Blue Dynasty F1
• Victoria F1
• Pruktor
• Copenhagen Market

These varieties produce firm heads with strong disease tolerance.

Nursery Establishment

Prepare a fine-textured nursery bed in a well-drained area. Mix topsoil with sand for aeration. Next, treat the bed with an appropriate fungicide to prevent damping-off. Sow seeds evenly, cover lightly, mulch, and water gently. Within 4–6 weeks, seedlings will be ready for transplanting. How to Prepare and Manage a Seedling Nursery

3. Transplanting

Steps

Transplant seedlings once they reach 12–15 cm height and have 4–6 true leaves. Water the nursery thoroughly before lifting seedlings to reduce stress.
Spacing:

• 60 × 45 cm (smaller varieties)
• 75 × 60 cm (large-headed varieties)

Pre-plant Treatments

Before transplanting, apply a starter fertilizer such as DAP to promote strong root development. Additionally, apply termiticides in termite-prone soils and use pre-emergent herbicides around the beds to reduce early weed competition.

4. Fertilizer Application Program

Establishment Phase (Week 1–3)

Use NPK 17:17:17 at 75–90 kg per acre. This supports early root and vegetative development.

Rapid Vegetative Growth Phase (Week 3–6)

Apply CAN at 50–70 kg per acre depending on soil fertility.
Moreover, nitrogen at this stage significantly enhances leaf development, which determines final head size.

Head Formation Phase (Week 6–10)

Switch to NPK 10:26:26 or Calcium Nitrate at 40–50 kg per acre. This improves head firmness and reduces cracking.

Micronutrient Support

Apply foliar feeds rich in calcium, magnesium, and boron every 10–14 days. These nutrients help prevent physiological disorders and improve head quality.

5. Irrigation Management

Consistent moisture is essential for cabbage. For best results, adopt drip irrigation to supply uniform water while reducing leaf wetness that encourages disease. Water at least twice a week during dry periods. However, avoid waterlogging, as it increases the risk of root rot and fungal infections.

6. Weed Management

Cabbage is sensitive to early weed competition. Therefore, apply pre-emergent herbicides after transplanting and use selective herbicides during crop development. Shallow hand weeding is also helpful, but take care not to disturb the roots.

7. Pest & Disease Management

Common Pests

• Diamondback moth
• Aphids
• Cutworms
• Cabbage looper

Common Diseases

• Black rot
• Downy mildew
• Fusarium wilt
• Alternaria leaf spot

Protection Schedule

Stage	Treatment	Purpose
Early growth	Preventive fungicide	Controls damping-off & leaf diseases
Continuous	Insecticide rotation	Reduces moths, loopers & aphids
Mid-late	Systemic fungicides	Manages black rot & mildew

Furthermore, rotating chemicals improves efficacy and reduces resistance risks.

8. Head Formation & Maintenance

As heads begin forming, ensure watering is consistent but not excessive. Additionally, avoid late nitrogen applications since they can delay maturity or cause loose heads.

Remove old leaves touching the soil to improve aeration and reduce disease pressure.

9. Harvesting

Harvest when heads are firm and compact. Use a sharp knife and cut slightly above the soil line. As a result, the plant remains clean, and post-harvest damage is minimized.

For market freshness, avoid exposing harvested heads to direct sunlight.

Key Takeaways

• High-quality seeds guarantee stronger seedling establishment
• Balanced fertilization improves head size and uniformity
• Regular scouting prevents pest outbreaks
• Good irrigation practices ensure firm, market-ready heads
• Timely harvesting prevents splitting and quality loss
