- Observation Pea/oat mix produced 5036 kg ha −1 above-ground dry matter.
- Observation Hairy vetch produced 5032 kg ha −1 above-ground dry matter.
- Observation Sweetclover produced 4064 kg ha −1 above-ground dry matter.
- Observation Lentil produced 3589 kg ha −1 dry matter, among the lowest.
- Observation The seven-species mixture produced 3551 kg ha −1 dry matter, among the lowest.
- Observation Soybean produced 3174 kg ha −1 dry matter, among the lowest.
- Observation Pea/oat was among the most weed-competitive green manures, with less than 15% weed dry matter.
- Observation Hairy vetch was among the most weed-competitive green manures, with less than 15% weed dry matter.
- Observation Grazing utilization of green manures varied little among species and ranged from 28 to 86%.
- Intervention effect Grazing increased nitrogen availability to wheat.
- Intervention effect Grazing significantly increased wheat dry matter production.
- Intervention effect Grazing significantly affected wheat nitrogen uptake, which averaged 107 versus 98 kg N ha −1 in grazed and ungrazed plots.
- Intervention effect Grazing significantly affected wheat grain nitrogen.
- Intervention effect Grazing had no statistically significant effect on wheat yield.
- Intervention effect Fall rye productivity was unaffected by grazing.
- Recommendation The authors recommend pea/oat green manure for overall system performance.
- Recommendation The authors recommend hairy vetch green manure for overall system performance.
