Sugar Beet - Growth retardation
Symptoms
Growth is stunted, and the plants have a stiff upright appearance. Leaves and petioles can become brittle.
Starting from the inner leaves, the foliage of the entire plant including the veins turns chlorotic yellow.
Causes
Sulphur deficiency (right).
Early symptoms of S deficiency may be confused with those of N deficiency. In both cases, leaves fade gradually from green to a light yellow-green. Later on, the heart leaves of S deficient plants become light green to almost yellow in contrast to the deep green with N deficiency.

Sulphur deficiency made worse by
- Acidic soils
- Light, sandy soils (leaching)
- Low organic matter
- Poorly aerated soils (waterlogged soils
- ) Areas with low industrial emissions
Sulphur is important for
- Better crop development
- More efficient use of nitrogen by the crop
