Applying silicon and zinc fertilizers to rice plants helps them grow better and produce more grains. The study found that using these fertilizers together increased the number of rice spikes and reduced empty shells in the grains. This led to a significant increase in rice yield. The combination of silicon and zinc fertilizers also improved the pH value of the soil, preventing it from becoming too acidic. Overall, the research showed that using these fertilizers can boost rice growth and yield in different types of soil.
