Weather Effects on Expected Corn and Soybean Yields

by Paul Westcott and Michael Jewison

Weather during the growing season is critical for corn and soybean yields. Adjusting for weather in an analysis of historical U.S. corn and soybean yields is important for determining underlying trends and future yield expectations. Models for U.S. corn and soybean yields provide estimates of the effects of weather on yields for those crops.
