- Intervention effect Silicon reduced leaf blast on partially resistant and susceptible rice cultivars as its rate increased.
- Intervention effect Silicon reduced neck blast on partially resistant and susceptible cultivars as its rate increased.
- Intervention effect At some locations, silicon at 500 or 1,000 kg/ha lowered leaf blast severity in partially resistant cultivars to that of resistant cultivars without silicon.
- Intervention effect Silicon at 1,000 kg/ha increased rice yield by up to 42%, depending on cultivar.
- Intervention effect High silicon rates reduced broken grains.
- Intervention effect High silicon rate reduced grain discoloration by up to 70%.
- Recommendation The authors propose silicon supplementation of host resistance for rice disease management and improved yield quantity and quality.
