Abstract

Current cropping practices in Iowa have reduced diversity in crop production to predominantly corn and soybean. Low prices, weed and pest control problems, and erosion have plagued these monoculture crop systems. Small grains and forages represent potentially viable alternative crops to corn and soybean in Iowa. Producers could opt for an annual intercrop that provides grain and forage without taking land out of corn and soybean for more than one year. This project tested the possibilities for combining small grains with a forage crop for a one-year intercrop.
