- Observation The lowest average 0–80 cm soil water content occurred under I95 in 2015.
- Observation The lowest average 0–80 cm soil water content occurred under I100 in 2016.
- Intervention effect Irrigation level influenced soil temperature more at 5 cm than at other depths.
- Association Soil temperature increased as irrigation decreased and growth progressed.

- Observation Root length density differed significantly among lateral positions in the 0–20 cm layer.
- Intervention effect Deep-layer root length density was greater under I75 in 2015 than at other depths.
- Intervention effect Deep-layer root length density was greater under I80 in 2016 than at other depths.
- Intervention effect Grain yield, WUE, and PFP increased with irrigation level in 2015.
- Intervention effect Grain yield, WUE, and PFP rose then fell as irrigation increased in 2016.
