By 2016, organic production increased to 5,019,496 acres in the U.S., with 186,178 acres in organic vegetable production. In the most recent Iowa survey (2018), Iowa had 902 acres of certified organic vegetables, contributing $4.2 million in annual sales. Organic farming has been shown to improve soil quality and contribute to food safety and quality. This experiment, conducted in 2019, at the ISU Neely-Kinyon Farm in Greenfield, IA, examined the effect of cover crops and reduced tillage on organic tomato production and postharvest quality. Food quality analysis was performed in the ISU Department of Food Science and Human Nutrition. Results showed no significant differences in color of fruit, soluble solids content (SSC), titratable acidity (TA) or pH between treatments, but a trend towards lower SSC in the treatment without cover crops or mulch. Yields were lower in organic no-till plots, but previous research has shown greater soil quality in this treatment.
