Using Participatory Variety Trials to Assess Response to Environment in Organic Vegetable Crops

About the Webinar

Beginning in 2010, the Northern Organic Vegetable Improvement Collaborative (NOVIC) has been conducting participatory vegetable variety trials on a network of organic farms across the northern U.S. While critical for producing findings that accurately reflect working farms, participatory research poses unique challenges in terms of data quality and analytical methods. Alexandra Lyon, a PhD student who has been working for NOVIC since 2010, will discuss a straightforward, graphical approach that uses the NOVIC variety trial data to assess the stability of variety performance across variable environments. From this work, future participatory breeding and variety trial efforts can be better informed and made more efficient and effective. This webinar is meant for an audience of researchers, farmers, and other professionals interested in farmer collaboration and participatory research.
