Symptoms
S deficient plants show a bright chlorotic, yellow green colour and stunted growth. Chlorosis caused by sulfur deficiency can often be observed at the young leaves first - in contrast to deficiency symptoms caused by a lack of nitrogen.
The number of grains sites and the size of grain is reduced under S deficiency.
Reasons
Sulphur deficiency (right)
N deficiency and root damage may cause similar symptoms. Symptoms of N and S deficiency in wheat and other small grains are very similar, thus a tissue analysis is often necessary to reveal the cause.
