Several varieties are available that are capable of producing high yields.
I would plant the bulk of my acreage in a proven performer on your farm. Plant a small acreage of any new varieties that may have preformed well in your area.

Be sure you need the specific gene pack age and be sure the gene package is in a variety that is adapted to your farm.
