CFSA’s Southeast Organic Seed and Variety Trial Report was developed to support organic growers in two ways: to increase access to variety trials results and to provide a significant listing of organic seed purveyors.
In 2014, CFSA sought to compile the results of variety trials conducted under organic management throughout the southeastern region. The unfortunate reality is that there is very little data available concerning which varieties are suited to the unique management techniques, regional conditions and market demands that organic growers in the Southeast face. Organic growers typically source and manage on-farm fertility using a variety of inputs and lack the production aids conventional system employ to ward off pest, disease and weed pressure. Therefore, data from conventional trials are less meaningful for organic systems.
CFSA reached out to those growers who have been making headway on this issue to fill our current void of information for variety selection. The report compiles contributions from seed producers, extension staff, researchers, and farmers who have been engaged in this critical work. Reports were split into two categories. First, we’ve grouped variety trials that were replicated so that cultivar performance could be compared statistically. In the second section, you’ll find observational trials that were not replicated but still offer helpful information on variety performance. We sincerely thank each of the contributors to this report for their efforts and willingness to share trial findings.
The final section of our report lists purveyors of certified organic seed. The USDA National Organic Program standards require that organic crop producers use organically grown seed – and this provision includes both cash and cover crops. While the industry continues to grow, it can be challenging for growers to track down companies that offer certified products. Our hope is that this robust (although not comprehensive) list will help growers source compliant organic seed. If you use or know of a company that should be added to this list, please contact us so we can include their information.
