Effects of optimized nitrogen fertilizer management on the yield, nitrogen uptake, and ammonia volatilization of direct‐seeded rice

Abstract

Optimized N fertilizer management achieved delayed senescence (maintenance of higher leaf Soil Plant Analysis Development meter values in late reproduction), higher canopy photoassimilation (suitable leaf area), higher N fertilizer use efficiency, and less N loss (lower cumulative NH₃ volatilization). © 2023 Society of Chemical Industry.
