Farmers are continually searching for a third crop to complement the corn-soybean rotation. Field peas can be substituted for most of the soybean meal in swine rations and is more economical than soybean meal,so there is a huge potential market for field peas in Iowa. Field peas are a short season crop which makes double cropping a potential possibility.
