• Blended controlled-release nitrogen fertilizer increases rice post-anthesis nitrogen accumulation, translocation and nitrogen-use efficiency (2024) · Frontiers in Plant Science · cited 9× · doi

  There is a lack of knowledge on the effects of blended controlled-release nitrogen fertilizer on rice yield and nitrogen-use efficiency. The conventional practice of split applications of urea has limitations, and there is a need for alternative fertilizer management practices. The study aims to address the gap in knowledge on the optimal nitrogen application rate for blended CRN treatment.

• Enhancing root physiology for increased yield in water-saving and drought-resistance rice with optimal irrigation and nitrogen (2024) · Frontiers in Plant Science · cited 12× · doi

  Further studies are needed to explore the effects of different irrigation regimes and NFAR on grain yield in various rice varieties. Research on the optimization of water and nitrogen management for high-yield and water-efficient irrigation production in rice is necessary. Investigations on the relationships between root and shoot morphophysiology and grain yield in different rice varieties are required.
