- Intervention effect Earlier fall cover-crop planting raised biomass about 2,000 kg ha −1.
- Intervention effect Each 10-day delay in spring termination raised cover-crop biomass about 2,000 kg ha −1.
- Method / resource A thermal model separating fall and spring heat units best estimated cereal rye biomass.
- Observation Cereal rye cultivars differed in total biomass accumulation.
- Observation Established cereal rye cultivars had similar growth rates.
- Observation Aroostook rye emerged earlier than Wheeler.
- Intervention effect Aroostook rye suppressed weeds more than Wheeler.
- Observation The rye-hairy vetch mixture had weed suppression intermediate between the two rye cultivars.
- Intervention effect Delaying cover-crop termination reduced weed density, especially early and late emerging summer annual weeds in 2006.
- Intervention effect Yellow nutsedge was unaffected by cover-crop type.
- Intervention effect Yellow nutsedge was unaffected by cover-crop management timing.
