Introduction
- Zinc importance in plant nutrition is recognized after the introduction of
high yielding varieties. - Zinc deficiency caused by intensive cropping.
- 80% of rice land deficient in zinc.
- After N and P zinc playing an important role in rice.
Role in Plant System
- Producing several enzymes
- Responsible for chlorophyll formation.
- Deficiency reduce photosynthetic activity.
- Playing a role in N – metabolism.
- Regulate auxin (hormone) production
- Promotes nucleic acid production for protein synthesis.
Injury Due To Excess Fertilizer
- Excess zinc cause deficiency of Iron.
Deficiency Symptoms
- Appearance of rusty brown spots and discoloration of older leaves starting from 2-3 weeks after planting.
- Uneven crop stand.
- Under acute conditions margins of older leaves dry up.
- Under acute conditions margins of older leaves dry up.
- Tillering and growth adversely affected (KHAIRA disease)
- Fresh leaves smaller in size.
- No uniform maturity of crop.
Management of Zinc for Rice
- 50 kg of Zinc Sulphate /hector to soil in the final puddling in every Rabi season in double cropped wet lands.
- Once in 2-3 crops in single cropped areas.
- Give a gap of 4-5 days between application of phosphorus and Zinc since Zn has antogonistic effect with phosphorus.
- Zinc deficiency in standing crop can be corrected by spraying 0.2% zinc sulphate solution (2g/lt of water) about 500 liters of spray solution is required to cover one hectare.
- Spraying should be repeated 2-4 times at an interval of 5-10 days
Sources:
- Zinc Sulphate – Zn SO4 7H2O (21%Zn)
- ZnSO4 H2O (33% Zn)
- Chelated Zinc (12% Zn) – is costly
- Chelated Zinc (14% Zn)
