Other claims from this paper (13)
- Observation Crofton weed (A. adenophora) showed 95–100% crown cover throughout invaded ridges/risers of terraced fields.
- Observation Crofton weed had stem densities of 134–208 individuals per m2 on invaded ridges/risers.
- Observation Crofton weed had an average basal area of 0.15 cm2.
- Intervention effect Total mean density of herbs other than A. adenophora decreased by 38–85% on invaded ridges/risers compared with uninvaded ridges.
- Intervention effect Species richness of herbs increased by 31–37% on invaded ridges compared with uninvaded ridges.
- Observation Soil nutrient availability was high across invaded ridges/risers and crop fields.
- Observation Average irradiance near invaded ridges was 1.8 ± 0.31%, much lower than 19.6 ± 1.80% near uninvaded ridges.
- Association Rice straw, root and grain yields near uninvaded ridges were reduced by 27%, 19% and 33% relative to the farthest distance.
- Association Rice straw, root and grain yields near A. adenophora-invaded ridges were reduced by 37%, 39% and 43% relative to the farthest distance.
- Association Soybean straw, root and grain yields near uninvaded ridges declined by 62%, 66% and 42% relative to the farthest distance.
- Association Soybean straw, root and grain yields near A. adenophora-invaded ridges decreased by 59%, 69% and 47% relative to the farthest distance.
- Association Soybean harvest index increased by 15% (uninvaded) and 10% (invaded) ridges relative to the farthest distance.
- Observation The authors conclude that Crofton weed could suppress field crops and form a single dominant population in the invaded area.
