- Intervention effect Root pruning at bloom reduced cumulative apple yield by 14%.
- Intervention effect Root pruning in mid-June reduced cumulative apple yield by 20%.
- Intervention effect Root pruning reduced cumulative yield efficiency, with little difference among pruning times.
- Intervention effect Root pruning reduced biennial bearing intensity regardless of pruning time.
- Intervention effect Root pruning decreased the number of large fruit in three of six years.
- Intervention effect Root pruning increased the number of small fruit in three of six years.
- Intervention effect Yield-adjusted analysis showed root pruning reduced average fruit size.
- Intervention effect Root-pruned trees produced firmer fruit and higher soluble solids.
- Intervention effect Root pruning increased fruit soluble solids concentration.
- Intervention effect Root-pruned trees had less preharvest fruit drop than nonpruned trees.
