Technical Abstract: Potato cropping systems in New England include both continuous potatoes and potatoes rotated with small grains. Producers recognize the benefits of increased rotations, but the economics of producing a high-valued crop, such as potatoes, create incentives for continuous potato production. Research at the USDA-ARS research site in Newport, Maine is evaluating the agronomic and economic impacts of six crops in two-year rotations on potato yield and whole-farm profitability. Preliminary results show that certain rotation crops have a positive impact on the following potato crop. The impact on yield can reduce nitrogen needs and production costs. Simulation was conducted to determine the impact of rotation crops on whole-farm profitability and income risk. Rotation crops, such as sweet corn, can increase financial return to land and management. Several crops, while not increasing overall whole-farm profitability, were found to significantly reduce income risk. These findings provide support for including rotation crops as a method to improve potato production and sustainability, increase whole-farm profitability, and reduce income risk.
