- Intervention effect Sixty percent shade increased corn chlorophyll relative to full sun.
- Intervention effect Sixty percent shade reduced corn leaf area and height relative to full sun.
- Intervention effect Double density plants had 11% less chlorophyll than single density plants.
- Intervention effect Double density plants had leaf area and height similar to shaded plants.
- Intervention effect Double density increased water and nitrogen use efficiency.
- Intervention effect Double density increased yield per hectare by 11%.
- Intervention effect Sixty percent shade reduced yield per plant by 50%.
- Intervention effect Double density reduced yield per plant by 50%.
- Mechanism The authors attributed shaded plant yield reduction to light stress.
- Intervention effect High density was associated with a 20% decrease in red to near infrared ratio.
- Mechanism The authors linked the density induced ratio decrease to downregulation of three carbon metabolism enzymes.
- Observation High density and shade had similar per plant yield impact but different compensation mechanisms.
