2006 Annual Report 4d.Progress report. This report serves to document research conducted under a reimbursable agreement between ARS and Washington State University. Additional details of research can be found in the report for the parent 1931-21000-015-00D Integrated Orchard Management and Automation for Deciduous Tree Fruit Crops. The experimental sweet cherry harvester developed at the Appalachian Fruit Research Station was loaned to Dr. Matthew D. Whiting, Washington State University, Prosser, WA for the 2004, 2005 and 2006 season. Dr. Whiting is developing and evaluating sweet cherry cultivar characteristics, cultural practices, and tree training systems for compatibility with machine harvest. Annual harvest trials determined the optimum parameters. This project supplements the parent CRIS by providing detailed information on Component 2 (Agroengineering, Agrochemical, and Related Technologies), problem statement 1 (Automation and Mechanization to Improve Labor Productivity) in National Program 305.
