- Intervention effect Retaining more fruiting nodes per vine increased Concord grape yield.
- Intervention effect Retaining more fruiting nodes per vine reduced Concord grape fruit quality.
- Intervention effect Geneva double curtain training produced more Concord grape fruit than single wire cordon training.
- Intervention effect Geneva double curtain training produced better Concord grape fruit quality than single wire cordon training.
- Intervention effect Shoot positioning increased Concord grape yield in the following season.
- Intervention effect Shoot positioning improved Concord grape fruit quality during the season it was performed.
- Intervention effect Pruning Concord grape vines to 6-node canes increased yield compared with 3-node spurs.
- Intervention effect Pruning Concord grape vines to 9-node canes increased yield compared with 3-node spurs.
- Intervention effect Pruning Concord grape vines to 6-node canes did not sacrifice fruit quality relative to 3-node spurs.
- Intervention effect Pruning Concord grape vines to 9-node canes did not sacrifice fruit quality relative to 3-node spurs.
- Intervention effect Pruning Concord grape vines to 6-node canes reduced the yield-increasing potential of shoot positioning compared with 3-node spurs.
- Intervention effect Pruning Concord grape vines to 9-node canes reduced the yield-increasing potential of shoot positioning compared with 3-node spurs.
- Recommendation The authors suggest that longer canes, GDC training and shoot positioning in Arkansas may permit less severe pruning than the 30+10 schedule to increase grape yield without losing fruit quality.
- Intervention effect Treatments increasing Concord grape yield generally reduced pruning weights.
