Seed Corn Hartung Brothers main seed corn production areas are in Wisconsin and Illinois. HBI does the planting of the seed corn. Our fields are 100% irrigated and rotated yearly. Seed Corn has male and female rows. Seed corn requires roguing and detasseling. The HBI fields are scouted on a regular basis to make sure they are growing a healthy crop. Once the seed corn is harvested, H & N Logistics, LLC is responsible for the transferring of the seed corn to our local seed plants - Madison, WI and Muncie, IL. It is then dried and bagged. The seed corn is sold wholesale or bagged to be planted as field corn.
