Apple Replant Research Project, Fruit Research and Extension Center

When evaluating new apple planting options for an orchard, it is important to assess the factors, which influence productivity and profitability. One condition which influences productivity is the apple replant problem. Replant has been recognized as a major cause of poor vigor and delayed cropping in new plantings. The loss of income from replant problems in a new apple planting can be high.

The treatments evaluated in this project include, corn/corn rotation, rapeseed/rapeseed rotation, composted animal manure, monoammonium phosphate and an immediate replant with chemical fertilizer.

Details of this project can be found in:
2003 SHAP Progress Report (PDF format).
