Cereals - Spots

Symptoms
In the present case, a mature leaf exhibits irregular light brown lesions, bordered by a dark brown margin.

Reasons
Zinc deficiency

Cereals - Growth retardation

Symptoms
Affected plants are paler in colour than normal and the leaves have a purplish tint. Necrotic spots (often light brown with dark margin) occur on the older leaves. Growth is also reduced due the affect of zinc on chlorophyll function. Internodes are shortened.

Reasons
Zinc deficiency

Cereals - Chlorosis

Symptoms
Medium leaves show interveinal chlorosis.

Reasons
Zinc deficiency on durum wheat

Zinc deficiency made worse by

  • Organic soils
  • High pH soils
  • Soils rich in phosphorus
  • Soils receiving high phosphorus application
  • Cold wet conditions

Zinc is important for

  • Increased fertility (number of grains per ear)
  • Better grain quality
