Cereals - Growth retardation

Symptoms
The number of grains sites and the size of grain is reduced under S deficiency. S deficient plants show a bright chlorotic, yellow green colour and stunted growth. Chlorosis caused by sulphur deficiency is observed at the young leaves first.

Reasons
Sulphur deficiency N deficiency and root damage may cause similar symptoms.

Cereals - Growth retardation

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.

Cereals - Growth retardation

Symptoms
Ears are small.

Reasons
Sulphur deficiency (left)

Cereals - Growth retardation

Symptoms
Leaves of S deficient plants exhibit a bright yellow-green chlorotic colour. Chlorosis normally starts on the young leaves. The whole plant including the ears shows stunted growth and yields poorly.

Reasons
Sulphur deficiency Symptoms of N and S deficiency in cereals are very similar, thus a tissue analysis is often necessary to reveal the cause.

Sulphur deficiency 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

  • Healthy green foliage
  • Even crop maturity
  • More efficient use of nitrogen by the crop
  • Improved grain protein contents

Yara recommended fertilizers for Sulfur

YaraVita THIOTRAC 300

YaraVita THIOTRAC 300

Cereals: 5 l/ha at pseudo stem erection to first node detectable (Zadok's G.S. 30 to 31). For moderate to severe deficiency, repeat applications at 10 to 14 day intervals. Water rate: 200 l/ha. Milling wheat only: Up to 5 l/ha from ear fully emerged to the end of the milk development stage in grain ripening (Zadok's G.S. 59 to 79) or two applications of 3 l/ha in the period flag leaf ligule just visible to the end of the milk development stage in grain ripening (Zadok's G.S. 39 to 79). Water rate: 200 l/ha.
