Rice - Discolouration
Symptoms
Older leaves show a bronze tint starting from the leaf margins thus the midrib remains green for a longer while.
Reasons
Zinc Deficiency
(Hudda disease - Pakistan, Khaira disease - India)
Rice is sensitive to Zn deficiency.
Rice - Discolouration
Symptoms
Older leaves show a bronze tint starting from the leaf margins thus the midrib remains green for a longer time.
Tips of older leaves wither and become white.

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
- Efficient photosynthesis (sugar production)
- Healthy crop
- Strong, early vigour
- Grain formation (yield)
