Other claims from this paper (9)
- Intervention effect Shorter root fragments produced lower mean shoot height than longer fragments.
- Intervention effect Longer root fragments produced plants with higher dry weight than shorter fragments.
- Intervention effect Longer root fragments produced plants with more nitrogen than shorter fragments.
- Intervention effect Dry matter production per square meter did not differ among initial root-fragment populations.
- Intervention effect Dry matter allocation among leaves, stems, buds and roots at harvest did not differ among populations.
- Intervention effect Nitrogen allocation among leaves, stems, buds and roots at harvest did not differ among populations.
- Observation Nitrogen was reallocated from leaves and stems to roots over time.
- Association Initial root length per square meter predicts harvest biomass better than fragment number per square meter.
- Recommendation Root fragmentation may be an effective weed control measure with a crop competitive for light.
