Cabbage - Growth retardation
Symptoms
General plant development is delayed and growth is stunted. White cabbage develops succulent, brittle leaf tissue. Headforming is inhibited and crops are more susceptible to fungal infections.
Reasons
Sulphur deficiency (left)
S deficiency can easily be confused with lack of N. Symptoms like delayed and stunted growth are similar, but chlorosis occurs on younger leaves first with S undersupply, whereas N deficiency symptoms are first visible on older foliage.

Cabbage - Growth retardation
Symptoms
Young plants show chlorosis of the younger leaves. General plant development is delayed and growth is stunted. Headforming is inhibited and crops are more susceptible to fungal infections.

S deficiency can easily be confused with lack of N. Symptoms like delayed and stunted growth are similar, but chlorosis rather occurs on younger leaves first with S undersupply, whereas N deficiency symptoms are first visible on older foliage.

Reasons
Sulphur deficiency (right)
S deficiency can easily be confused with lack of N. Symptoms like delayed and stunted growth are similar, but chlorosis occurs on younger leaves first with S undersupply, whereas N deficiency symptoms are first visible on older foliage.
Sulphur is required in relatively high quantities in brassicas. A steady supply of S throughout the season is needed.

Symptoms
General plant development is delayed and growth is stunted. The youngest developing leaves show uniform chlorosis.

Sulphur deficiency vs. healthy plant made worse by
- Acidic soils
- Light, sandy soils (leaching)
- Low organic matter
- Poorly aerated soils (waterlogged soils
- ) Areas with low industrial emissions
Sulfur is important for
- Requirement of steady supply in relatively high quantities
- Important for head development and stress tolerance
- Major role in crop quality
- Better inner quality determinants and improved storage quality
