Effects of controlled-release mixing fertilizers on rice yield

Field trial was conducted to evaluate the application effects of controlled-release mixing fertilizers on rice. The results showed that application of controlled-release mixing fertilizers was beneficial to rice yield. Compared with conventional fertilization, application of controlled-release mixing fertilizers with same nutrients, 10% decrement, 20% decrement could increase yield by 7.1%, 4.2%-6.1%, -8.5%, respectively. The controlled-release mixing fertilizer (No. 1) had the most economic benefits among the fertilizers in field trial, suggesting that the amount of fertilizer was 45 kg per 667 m2, and it may had potential as a commercial fertilizer.
