Cabbage is a crop that requires adequate nutrition to produce large, heavy, high-quality heads that meet market requirements. Successful cabbage production does not depend on fertilizer alone. It also requires quality seed, healthy soil, proper irrigation, timely weeding, and effective pest and disease management.

For a farmer cultivating one acre of cabbage, it is important to have a fertilizer program that matches the different growth stages of the crop.

Important: The exact fertilizer rates per acre should be determined based on soil-test results, cabbage variety, field conditions, irrigation system, and production target. Do not apply fertilizer rates routinely without professional advice.

STEP 1: TEST THE SOIL BEFORE PLANTING

Timing: Before preparing the field.

The first step is to conduct a soil test.

A soil test can help determine:

• Soil pH.
• Nitrogen (N).
• Phosphorus (P).
• Potassium (K).
• Other nutrients, depending on the type of test.

Why is soil testing important?

Because fertilizer requirements vary from one field to another.

Do not purchase or apply large amounts of fertilizer before understanding the needs of your field.

STEP 2: LAND PREPARATION

Timing: Before transplanting seedlings.

Manure or Compost

Apply well-decomposed manure or compost during land preparation.

It can help to:

• Increase organic matter in the soil.
• Improve soil structure.
• Help the soil retain moisture.
• Improve the root environment.

Basal Fertilizer

Depending on soil-test results, a fertilizer containing Phosphorus (P) may be applied during land preparation or at transplanting.

Fertilizers such as DAP or MAP may form part of the program where Phosphorus is required.

Do not use DAP or MAP routinely without considering the actual needs of the soil.

STEP 3: TRANSPLANTING THE SEEDLINGS

Timing: On the transplanting day.

Use healthy seedlings that are ready for transplanting.

At this stage, consider the following:

✓ Ensure the roots are healthy.
✓ Make sure the soil has adequate moisture.
✓ Avoid transplanting during extreme heat without proper preparation.
✓ Do not allow concentrated fertilizer to come into direct contact with the seedling roots.
✓ Use appropriate spacing according to the cabbage variety and production system.

Important nutrients

• Phosphorus for root development.
• Nitrogen for early growth at an appropriate rate.
• Other nutrients according to soil requirements.

STEP 4: WEEK 1–2 — SEEDLING ESTABLISHMENT

During the first weeks, cabbage plants begin developing stronger roots and producing new leaves.

Fertilizers that may form part of the program include:

• NPK.
• CAN.
• Urea where additional Nitrogen is required.

Objective

Strengthen the roots and establish healthy leaf growth.

Farmers should monitor:

✓ Seedling establishment
✓ New leaf development
✓ Soil moisture
✓ Signs of pests and diseases
✓ Signs of nutrient deficiencies

Avoid excessive Nitrogen, because over-application can lead to unbalanced plant growth.

STEP 5: WEEK 3–5 — LEAF DEVELOPMENT

At this stage, cabbage plants begin producing leaves rapidly and building the foundation for head formation.

Nutritional focus

• Nitrogen at the required level.
• Phosphorus according to soil conditions.
• Potassium in an appropriate balance.
• Other nutrients where required.

Fertilizers that may be used:

• NPK.
• CAN.
• Urea where additional Nitrogen is required.

With drip irrigation, fertilizers suitable for fertigation may be supplied through the irrigation system according to an appropriate program.

Do not apply large amounts of Urea or CAN without a proper plan.

STEP 6: WEEK 5–7 — HEAD FORMATION BEGINS

At this stage, the plant begins directing more of its growth toward forming the cabbage head.

Focus on:

• Balanced nutrition.
• Nitrogen at an appropriate level.
• Potassium.
• Calcium and Magnesium where required.
• Micronutrients according to crop condition.

Objective

Support the development of a firm, heavy, and high-quality cabbage head.

Farmers should not increase Nitrogen routinely assuming that more fertilizer will automatically produce a larger head.

STEP 7: WEEK 7–9 — HEAD DEVELOPMENT

This is an important stage for achieving good cabbage size and quality.

Nutritional focus

Balanced Nitrogen + Potassium + required nutrients

Potassium is an important part of cabbage nutrition and supports several plant growth processes.

Consider the following:

✓ Maintain adequate and consistent irrigation
✓ Maintain balanced nutrition
✓ Control pests
✓ Manage diseases
✓ Remove weeds on time

STEP 8: WEEK 9–12 — HEAD MATURITY

As cabbage approaches maturity, farmers should focus more on head quality, weight, and firmness.

Focus on:

• Potassium according to crop requirements.
• Balanced nutrition.
• Appropriate irrigation.
• Avoiding excessive Nitrogen.
• Monitoring pests and diseases.

Do not apply fertilizer routinely as the crop approaches harvest.

STEP 9: HARVESTING

Cabbage should be harvested when the heads reach the appropriate size and maturity for the market.

Signs to consider

• The head is firm.
• The head has reached the desired size.
• The head has the firmness required by the market.
• There are no major signs of rot or disease.

Harvest on time to reduce the risk of splitting and loss of quality.

SIMPLE FERTILIZER SCHEDULE FOR ONE ACRE OF CABBAGE

IMPORTANT FERTILIZERS IN CABBAGE PRODUCTION

DAP/MAP

Provides Phosphorus along with other nutrients depending on the fertilizer formulation and is used where the soil requires it.

NPK

Provides Nitrogen, Phosphorus, and Potassium in the ratio contained in the particular formulation.

CAN

Provides Nitrogen together with Calcium and may form part of a top-dressing fertilizer program where required.

UREA

Contains approximately 46% Nitrogen and is a concentrated Nitrogen fertilizer. It should be used carefully according to crop requirements.

POTASSIUM FERTILIZERS

They are important components of cabbage nutrition, particularly during plant growth and head formation, depending on soil conditions.

CALCIUM AND MAGNESIUM

These nutrients may be important components of the nutrition program depending on soil condition and crop requirements.

MICRONUTRIENTS

Boron, Zinc, Iron, and other micronutrients may be required where deficiencies have been identified or confirmed.

FERTILIZER MISTAKES TO AVOID

❌ Applying fertilizer without testing the soil.
❌ Applying excessive Urea or CAN without a proper plan.
❌ Placing fertilizer directly against young seedling roots.
❌ Ignoring Potassium during head formation and development.
❌ Applying too much fertilizer at one time.
❌ Neglecting proper irrigation.
❌ Waiting until the cabbage shows severe nutrient deficiency symptoms.
