• No significant interaction was observed between stubble height and cover crop treatments.
• The winter hardy cover crop type resulted in corn yielding significantly lower than the winter sensitive or no cover crop plots.
• No impact on yield was observed for the different stubble heights. The low stubble height treatment was 8 inches, which is below the height considered to maximize stored soil moisture. However, precipitation was 4.3 inches above normal from May to July, 2018 at Gothenburg, which likely minimized yield differences among the treatments.
