Symptoms
Pale yellow chlorotic zones running parallel to the midrib starting at base of leaves. Leaf margin, tip and midrib remain green. The youngest developing leaves may be totally clorotic yellow or white ('white bud'). A reddish to necrotic brown discolouration at the leaf margins and the stems may develop on basal plant parts, when deficiency is severe.
Internode growth is reduced and leads to a stunted appearance.
Reasons
Zinc deficiency
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
- Good plant development early in the season
- Improves yield
- Brings harvest date forward
