Vegetable Trial Reports
The Department of Horticulture and Landscape Architecture and cooperating departments annually conduct experiments on field vegetable production. Data are reported for multiple aspects of each study and may include information on planting, harvesting, crop-quality, seed sources, and other related factors. Reports present data in text, table, and photo format providing up-to-date information on field research results. Results support OSU recommendations on vegetable production and are a valuable information resource for producers. Trial reports are available annually from 2001 through 2022. Reports are available as a PDFs that can be downloaded or viewed online. Contact Donna Dollins for a copy of older versions.
