Optimal Drip Irrigation Frequency and Volume Mitigates Photosynthetic Impairment and Balances Yield–Resource Trade–Offs for Spring Maize in Arid Sandy Loam Soils
Optimizing irrigation amount and frequency is critical for maize production in arid sandy loam soils, which are characterized by severe water scarcity and high leaching risks. This study aimed to determine the physiological and multi-objective synergistic responses of spring maize to different drip irrigation regimes i...
