- Intervention effect Increasing cotton density enhanced upper-canopy leaf area index.
- Mechanism Increased upper-canopy leaf area index led to higher upper-canopy FIPAR.
- Intervention effect High density lowered photosynthetic rate, chlorophyll content and leaf area relative to moderate density.
- Intervention effect High density lowered specific leaf weight relative to moderate density.
- Intervention effect Low and moderate density achieved maximum biomass in both years.
- Intervention effect Low and moderate density achieved maximum yield in both years.
- Intervention effect Moderate density had higher biomass-based light use efficiency in each canopy than low and high density.
- Association FIPAR was the dominant predictor of variation in biomass-based light use efficiency.
- Association Photosynthetic rate ranked second in predicting biomass-based light use efficiency variation.
- Observation Photosynthetic gene expression varied across canopy layers and planting densities in support of the light-use-efficiency pattern.
- Association The partial least squares model identified biomass-based light use efficiency and leaf photosynthesis as principal influences on yield.
- Intervention effect Moderate density optimized canopy light distribution and photosynthetic productivity in middle and upper canopies.
- Intervention effect Moderate density enhanced light use efficiency and yield potential.
