Workgroup Information

Vegetable Crops

Summary The workgroup brings together people who share common interests in vegetable crop issues to promote effective communication and interaction among the members. These people include faculty, extension specialists, and farm advisors in the UC. The objectives of the workgroup are to: 1) form a network to discuss research on specific vegetable crops; 2) provide a forum for members to exchange insights and experiences in their work and research; 3) discuss ways of disseminating vegetable-related information such as encouraging members to collaborate and providing information via the Vegetable Research & Information Center web site.
