| Impacts and Outcomes: | Human resource capacity development: M.S. student Callie Bolton In-row cover crops reduced vine vigor and weed biomass, mowing reduced weeding time and increased weed biomass as compared to clean tillage. However, future research is needed to determine if these factors positively or negatively impacts fruit yield and quality. Specialty in-row grape cultivator, Wonder Weeder, provided good in-row weed management but caused significant damage to young vines. Dissemination of information through workshops, field days and web sites. A new Extension publication on establishing a new organic vineyard is being developed. The organic vineyard established by this project is being used to investigate organic disease management options in western Washington. | |
