Effect of rotation and N rate on average corn yield

Rotation and N rate effects on average corn yield from 1979 to 2004. An upper case letter in the rotation code indicates the sequence in the rotation for the corn crop to which the graphed yield refers. For example, c-c-C-s indicates third-year corn of the corn-corn-corn-soybean rotation.
