New Western Washington Trial Report

The Greenbank Farm Organic Seed Project: 2015 Western Washington Trial Report is the result of on-farm variety trials conducted in 2014 and 2015 by organic farmers in Western Washington with technical advising support from both OSA and Greenbank Farm. The report includes descriptions of trial goals, trial methods, and trial result data of six on-farm variety trials conducted on four participating farms in Western Washington in 2015. Trials included varieties of tomatoes, dry pole beans, popcorn, radicchio, chicory, snap peas, and bush yellow snap beans. Download the report here
