Copper deficiency-Wheat | Yara Tanzania

Symptoms
Ears of Cu deficient plants are often trapped in the sheath and emerge with white tips and blind spikelets. Plants show dry, white and twisted or curled leaf tips (white tip). Young leaves wilt on their tips, whereas the basal leaves remain dark green.

Reasons
Copper deficiency Severe drought, heavy frosts and herbicide damage can cause blind ears, too.

Cereals - Wilting

Symptoms
Young leaves show dry, white and twisted or curled leaf tips (white tip). The basal leaves remain dark green. The complete plant growth is stunted.

Cereals - Deformation

Symptoms
Ears of Cu deficient plants are often trapped in the sheath and emerge with white tips and blind spikelets. Less severe symptoms may be seen as curved ears which do not ripen with an accumulation of the dark coloured melanin.

Cereals - Deformation

Symptoms
Ears are often trapped in the sheath and emerge with white tips and blind spikelets. Plants show dry, white and twisted or curled leaf tips (white tip).

Reasons
Copper deficiency

Cereals - Size reduced

Symptoms
Ears of Cu deficient plants show blind grain sites (blind spikelets) or poor grain formation. As the ears are lightweight they stand more upright than sufficiently supplied ones and give the plant a different habitus.

Reasons
Copper deficiency

Copper deficiency made worse by

Organic soils
Chalky soils
Sandy soils
Reclaimed heathland
High nitrogen applications

Copper is important for

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