Soybean growers in the mid-southern U.S. face many challenges imposed by adverse weather conditions that vary spatially and temporally. As a result, growers experience variations in soybean seed quality, grain quality, and yield. While not every harvest season experiences extremes in environmental conditions, those that do may result in major quality issues that could lead to significant financial losses. Therefore, the objective of this research was to evaluate quality as it relates to delayed harvest conditions for soybean following common management practices such as fungicide application to mitigate spread of pathogens or harvest aid application to facilitate more efficient harvest. Experiments were conducted in 2019 and 2020 to determine the impact that these soybean management practices have on soybean quality under delayed harvest conditions. Results indicate that soybean quality, regardless of planting date, was not impacted by fungicide or harvest aid treatment, but rather by harvest delay.
