Other claims from this paper (9)
- Intervention effect Alternate wetting and drying increased soil redox potential compared with continuous flooding.
- Intervention effect Alternate wetting and drying increased DTPA-extractable soil zinc compared with continuous flooding.
- Intervention effect Alternate wetting and drying increased rice grain zinc concentration by 9% over continuous flooding without a yield penalty.
- Association Fertilizer zinc at rates above 10 kg Zn/ha increased rice grain zinc concentration.
- Association Timing of fertilizer zinc application from basal to flowering had no effect on rice grain zinc concentration or yield.
- Association Alternate wetting and drying had a more consistent and larger positive effect on rice grain zinc than fertilizer zinc application.
- Observation The increase in rice grain zinc from fertilizer or water management was small, up to 2 mg Zn/kg brown rice.
- Recommendation Improved agronomic management alone is not sufficient to meet the target increase of at least 10 mg Zn/kg in rice grain.
- Recommendation Combined agronomic management is a useful complementary strategy for enhancing the performance of Zn-enriched rice.
