      • Leaf chlorophyll, LAI, and water potential as affected by tillage system
      • Diurnal variation of leaf photosynthetic parameters as affected by tillage system
      • Biomass, grain yield, ET, and WUE as affected by tillage system
    • Discussion
      • Subsoiling increased soil moisture retention and water uptake, and can ameliorate maize water stress
