Cabbage - Growth retardation
Symptoms
With nitrogen deficiency the foliage becomes yellowish-green (chlorotic). The symptoms start from the older leaves and after a while the whole plant becomes chlorotic, some leaf parts may have a reddish or orange flush.
The shape of the leaves remains normal.
Growth is strongly restricted, crop development is delayed and older leaves may decay.
With severe N deficiency, no head is formed.
Causes

Symptoms
With nitrogen deficiency the foliage becomes yellowish-green (chlorotic), some leaf parts may show a reddish or orange flush.
The symptoms start on the older leaves and after a while spread over the whole plant.
Desiccated, necrotic areas may occur additionally on the leaf blades.
The shape of the leaves remains normal, whereas their size is reduced.

Nitrogen deficiency vs. healthy plant made worse by
- Low or high pH soils
- Sandy or light soils (leaching
- ) Low organic matter
- Drought conditions
- High rainfall (leaching) or heavy irrigation
- Addition or high levels of non-decomposed organic matter/manure (eg straw)
- Fast growing crops
Nitrogen is important for
- High and early yields, good leaf size and market quality
