In this exploratory research project at the Rural Development Center in Salinas, CA., yield and quality in cherry tomatoes and beets improved after four years organic management and again after twelve years organic management. After fours years organic management, beet yield increased 1.76 kg. (3.89 lbs.) per sampled area (PSA) and 3.59 kg. (7.93 lbs.) after twelve years. Cherry tomato yield increased 3.51 kg. (7.75 lbs.) PSA after four years, and 7.17 kg. (15.80 lbs.) PSA after twelve years. Yield and quality for these two crops was compared on land in its first year, fourth year, seventh year, and twelfth year of organic management. Organic matter increased after twelve years and cherry tomato plant size increased with more years in organic. Results are preliminary, and only reflect one season. This study offers an important "snapshot" of the transition period after converting to organic production. The project models farmer collaborative, on-farm research into organic systems.
