Other claims from this paper (10)
- Observation Setaria sphacelata had higher total biomass, relative yield and competitive balance index than Ageratina adenophora.
- Observation Relative yield total was below one.
- Association The competitive relationships were more pronounced at lower community densities.
- Intervention effect Ageratina biomass in mixture fell 33.0% at 20 plants/m2 versus monoculture.
- Intervention effect Ageratina biomass in mixture fell 70.1% at 175 plants/m2 versus monoculture.
- Intervention effect Setaria biomass did not differ significantly between mixture and monoculture.
- Intervention effect Setaria root-to-shoot mass ratio was lower in mixture than monoculture.
- Intervention effect Ageratina root-to-shoot mass ratio was higher in mixture than monoculture.
- Mechanism The authors attributed suppression of Ageratina growth mainly to shoot competition from Setaria.
- Recommendation The authors proposed Setaria as a competitor for replacement control of Ageratina.
