e0“We evaluated no-tillage production of tomato ( Solanum lycopersicum L.), zucchini ( Cucurbita pepo L.), and bell pepper ( Capsicum annuum L.) planted into winter rye, hairy vetch, and a winter rye/hairy vetch (WR/HV) mixture that were mechanically suppressed with a roller–crimper at two locations in Minnesota”
e5“Soil growing degree-days (SGDD) were lower in cover crop treatments compared with the no-cover control, which could have delayed early vegetable growth and contributed to reduced yields”

- Intervention effect Average marketable yield of tomato in rolled cover crops was reduced 89% in 2008 compared with a no-cover control.
- Intervention effect Average marketable yield of tomato in rolled cover crops was reduced 65% in 2009 compared with a no-cover control.
- Intervention effect Average marketable yield of zucchini in rolled cover crops was reduced 77% in 2008 compared with a no-cover control.
- Intervention effect Average marketable yield of zucchini in rolled cover crops was reduced 41% in 2009 compared with a no-cover control.
- Intervention effect Average marketable yield of bell pepper in rolled cover crops was reduced 92% in 2008 compared with a no-cover control.
- Intervention effect Average marketable yield of bell pepper in rolled cover crops was reduced 79% in 2009 compared with a no-cover control.
- 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 Winter rye had higher average residue biomass than hairy vetch (5.3 Mg·ha −1 ) throughout the season.
- Association The WR/HV mixture had higher average residue biomass than hairy vetch (5.7 Mg·ha −1 ) throughout the season.
- 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.
