Reviving the grape industry in Iowa requires development of improved sustainable production systems. This project used research, demonstration, and information transfer to educate and assist new and established Iowa grape growers.
Can grapevines be grown in Iowa and can they be grown in a sustainable manner?
This project was undertaken to determine if grapevines can be grown using sustainable production practices under Iowa environmental conditions and to identify cultivars adapted to these practices in Iowa. Researchers developed experimental vineyards and initiated studies that will continue in future years to gain further information on fruit yield, quality, and disease tolerance. To date, they found differences in grape cultivar adaptation and tolerance to important diseases, some insects, and 2-4,D drift injury. Growing grapes in a sustainable manner using best management practices allowed for excellent grapevine growth and development. A system using organic-approved practices and products showed that weed control, fall cold tolerance, and nutrient and disease management will be critical for future consideration under this system.
