Sodium Chloride Enhances Nitrogen Use Efficiency but Reduces Yield Benefits Under Elevated CO<sub>2</sub> in Upland Rice

Climate-change-driven elevation of atmospheric CO<sub>2</sub> (e[CO<sub>2</sub>]) disrupts rice physiology by impairing nitrogen use efficiency (NUE) and leaf carbon balance. This study investigated how sodium chloride (NaCl) amendment modulates these processes in upland rice...
