Abstract

This article discusses some of the important factors to consider when contemplating corn on corn. Only the factors that apply to the individual producer will be discussed. There are a number of environmental and societal costs and benefits that are important; however, space does not permit going into that discussion here. The biggest factor in comparing the different rotations is the yield differences. Research has shown that there is a yield drag of approximately 5 to 15 percent for second-year corn relative to first-year corn. This yield difference varies by soil and location. The yield penalty is most prevalent in bad weather years.
