- Intervention effect Surface residue mechanical treatments killed flowering hairy vetch.
- Intervention effect Surface residue mechanical treatments did not kill vegetative hairy vetch.
- Intervention effect Mechanical treatments with cultivation controlled annual broadleaf weeds less well than herbicides.
- Observation Mechanical treatments kept final weed populations below threshold in two of four experiments.
- Intervention effect Stalk chopper and light disk left high surface vetch residue.
- Intervention effect Stalk chopper and light disk reduced initial broadleaf weed populations relative to heavy disk.
- Intervention effect Cultivation after stalk chopper or light disk reduced weeds by 38–69%.
- Intervention effect Cultivation after heavy disk reduced weeds by 87–95%.
- Observation Final weed populations were similar across mechanical pre-plant treatments.
