Aug 7, 2024Roger Duncan retires after transforming tree crop production
Roger Duncan, a prominent UC Cooperative Extension (UCCE) pomology farm advisor, retired on July 1 after 36 years of pioneering research and Extension work in tree fruit and nut crops. His contributions have significantly advanced almond, peach and grape production in California.
Duncan, who began his career with UCCE in 1988, has been instrumental in enhancing agricultural practices through innovative research on rootstocks, pruning methods, and disease management. His minimal pruning research, for example, challenged traditional practices and helped growers cut costs while boosting yields.
“Roger’s research has been crucial in improving productivity and quality,” said Mel Machado, vice president at Blue Diamond Almonds. “His work, particularly on pruning, transformed how we approach orchard management.”
Duncan’s efforts have led to a dramatic increase in the use of hybrid almond rootstocks and improved orchard designs, increasing profitability for growers. His research has also shaped educational programs for new farmers and expanded outreach through 4-H and Master Gardener programs.
“Roger provided invaluable resources and tools to growers, impacting the entire industry,” said John Duarte, nursery owner. “His departure is a significant loss, but his legacy will continue to influence farming practices.”
Duncan was recently honored with a Distinguished Service Award and granted emeritus status by UC ANR. For more information on Duncan’s work and UC Agriculture and Natural Resources programs, visit UCANR.
