Technical Abstract: The Old Rotation (circa 1896) is the oldest, continuous cotton experiment in the world. Its 13 plots on 1 acre of land on the campus of Auburn University continue to document the long-term effects of crop rotations with and without winter legumes (crimson clover) as a source of nitrogen for cotton, corn, soybean, and wheat. This is the third year that irrigation on the Old Rotation could be compared with non-irrigated plots. A very wet growing season resulted in no apparent yield increase due to irrigation for corn and cotton. A very dry fall did result in a soybean yield response to irrigation.
