- Association Winter rye reduced average annual weed density at St. Paul by 96% for 8 to 10 weeks after rolling.
- Association Hairy vetch mulch reduced weeds by 80% for 2 to 8 weeks after rolling.
- Association The WR/HV mixture had higher average residue biomass than hairy vetch (5.7 Mg·ha −1 ) throughout the season.
- Association Soil growing degree-days were lower in cover crop treatments than in the no-cover control.
- Mechanism Lower soil growing degree-days may have delayed early vegetable growth under cover crop treatments.
- Association All cover crop mulches were associated with low levels of soil nitrogen (less than 10 mg·kg −1 N) in the upper 15 cm.
- Recommendation Rolled winter annual cover crops show promise for controlling annual weeds in organic no-tillage systems.
