Cabbage and tomato farming

Choosing the right fertilizer for cabbages in Kenya significantly impacts the quality, size, and weight of your harvest. The best fertilizers for cabbage farming include:

Di-Ammonium Phosphate (DAP) – Boosts early root and leaf growth
NPK 17:17:17 – Ensures balanced nutrient uptake
Calcium Ammonium Nitrate (CAN) – Enhances head formation and firmness

To maximize cabbage yield and ensure healthy growth, timing and proper application of these fertilizers are key. Let’s break it down step by step.

1. Di-Ammonium Phosphate (DAP) – Best for Early Growth

Why Use DAP?

  • Provides high nitrogen content for vigorous leaf development
  • Supplies phosphorus for strong root formation

When to Apply: 10 days after transplanting
How to Apply:

  • Apply on moist soil to prevent leaching
  • Use in small quantities per plant to avoid root burn

Pro Tip: Avoid applying DAP directly to dry soil, as this may cause nutrient loss due to runoff.

2. NPK 17:17:17 – Promotes Uniform Growth

At the vegetative stage, cabbages need balanced nutrition to develop evenly. NPK 17:17:17 is ideal because it provides:

  • Nitrogen (N) for leafy growth
  • Phosphorus (P) for root strengthening
  • Potassium (K) for disease resistance and water regulation

When to Apply: 35 days after sowing
How to Apply:

  • Apply evenly around the base of each plant
  • Supplement with foliar fertilizers like Wuxal Macromix for extra micronutrients

Pro Tip: Foliar feeding enhances nutrient absorption, especially in cases of nutrient deficiencies or stress caused by harsh weather.

3. Calcium Ammonium Nitrate (CAN) – Ensures Firm, Compact Heads

At the head formation stage, applying high-nitrogen fertilizers can result in oversized leaves instead of compact heads. Instead, CAN fertilizer provides:

  • Calcium for strong cell walls and firmness
  • Ammonium nitrate for moderate nitrogen supply

When to Apply: At the onset of head formation

How to Apply:

  • Apply away from the base to avoid root damage
  • Avoid overuse, as excess nitrogen can delay head formation

Pro Tip: Never apply fertilizers directly onto cabbage leaves, as this can cause scorching and drying.

Conclusion: Choosing the Right Fertilizer for Cabbages

For optimal cabbage growth and maximum yield, follow a structured fertilizer application schedule and use high-quality fertilizers. Apply at the rate of 100kgs per Acre.

Key Takeaways:

  • DAP for early root development
  • NPK 17:17:17 for uniform vegetative growth
  • CAN for strong and compact head formation

By applying fertilizers at the right time and in the right way, you can boost productivity and improve cabbage quality.
