Organic Fertilizer Type and Rate Regulate Rice Canopy Function, Nitrogen Use Efficiency, and Yield Formation
Balancing rice yield and nitrogen use efficiency (NUE) under reduced nitrogen (N) input remains challenging. This study aimed to evaluate effects of fertilizer type and N rate on canopy function, yield formation, and NUE; examine source–sink relationships; and identify strategies balancing yield and NUE. A two-year fie...
