  1. The coefficients were estimated fitting linear regression models between first year differences (year-to-year changes) of yield (kg ha−1), of monthly maximum temperature (left) and monthly cumulative precipitation (right) generated for each of the 5 locations and each of the 7 growing season months from 1981–2013. The number in each cell is the month-specific yearly linear trend and was independently generated by holding constant the variation in all other cells. The location-specific data were aggregated to generate a southeastern US average for the same 7 months. Dashes denote statistically non-significant maize yield responses (P > 0.1).
