Optimization of One-Time Fertilization Scheme Achieved the Balance of Yield, Quality and Economic Benefits of Direct-Seeded Rice

There is limited information available to assess the impact of one-time fertilization on yield, quality, and economic benefits direct-seeded rice. This study reports effects three fertilizer treatments (BBU1, BBU2, BBU3) rice, where controlled-release nitrogen (N) (CRNF) provided 50%, 60%, 70% total N (270 kg ha−1), control treatment (CK) was a split application conventional urea (CU). The results showed that yield rice decreased significantly (p < 0.05) with increased ratio CRNF under fertilization, which mainly related accumulation between heading time maturity stages. Compared CK, maintained high milling reduced chalkiness 0.05), could be slow rate release from CRNF. In addition, protein content amylose milled improved eating quality 0.05). Furthermore, there no significant difference in benefit BBUI CK > Overall, replacing 50% helpful reduce frequency, achieve efficiency, improve fertilization.
