Rotation Impact on On‐Farm Yield and Input‐Use Efficiency in High‐Yield Irrigated Maize–Soybean Systems

Cereal yields tend to be higher in cereal–legume rotations relative to cereal monoculture yields. We investigated the influence of crop rotation on yield and input‐use efficiency in high‐yield irrigated maize ( Zea mays L.)‐based cropping systems using producer‐reported data from western U.S. Corn Belt (about 11,000 observations). Across regions, average yield of maize grown after soybean [ Glycine max (L.) Merr.] (S–M) was 0.2 to 0.6 Mg ha −1...
