Other claims from this paper (10)
- Association Shoot yield rose asymptotically with density.
- Method / resource The fitted yield density model best described yield per area for a time and density series.
- Association The fitted parameter w m rose over time.
- Association The fitted parameter a rose over time.
- Association Nutrient availability affected w m but not a.
- Association Density and time after sowing influenced individual size variability.
- Association CV declined linearly with log mean plant weight, with slope about -0.2.
- Observation Root weight variability exceeded total weight variability, which exceeded shoot weight variability.
- Mechanism Allometric growth partly explained differences in variability among yield components.
- Association Nutrient availability did not influence size variability.
