Improving Machine Harvest Efficiency and Fruit Quality for Fresh Market Blueberry

Investigators: L.W. DeVetter, F. Takeda, W. Yang, and J. Chen

Collaborators: Oxbo

We have been working to improve machine harvesting technologies for fresh market blueberry in collaboration with other researchers and private manufacturing companies. Drs. DeVetter and Yang were recently awarded Specialty Crop Block Grant funding from Washington and Oregon State Departments of Agriculture in 2018.  This will allow the research to continue for additional years and we hope viable, commercial technologies will soon become available to growers.


  1. Develop and test harvest technologies and practices that allow for the mechanical harvest of fresh market blueberry with high fruit quality and high harvest efficiency
  2. Packing line assessments
  3. Compare food safety risks associated with traditional and new harvesting technologies
  4. Assess the microbial quality of fruits harvested by hand and the modified OTR harvester prototyes
  5. Extend project information
