Abstract

Crop rotation and tillage systems have an impact on both production cost and yield. The use of an alternating corn and soybean rotation rather than continuous corn or soybean typically results in higher net return and lower variability since the economics of crop rotation are largely tied to the effect of introducing a break crop. However, limited research exits in Iowa with just corn and soybean in the rotations. The objective of this study was to determine the long-term effect on yield and profitability with continuous corn or soybean vs. rotated corn and soybean using different tillage systems. The study is conducted at two locations—Ames and the ISU Northwest Research Farm, Sutherland, IA.
