Minnesota and Wisconsin yield king at this maturity! Handles higher populations well with powerful roots and stalks. Strong emergence and early vigor with enhanced anthracnose stalk rot tolerance.


Goss’s tolerance is only average.


With this much yield potential, the area of adaptation is bound to expand. Keep populations up to a medium-high range for your area and feed this beast as it can produce top-end yields. Responds well to in-furrow microbials like Micro-Cycle.


The higher the number, the better the performance or rating.

We have had a really good run with Hefty Corn hybrids on our farm over the last several years. In fact, they have been our top-yielding hybrids for a number of years now.
Nathan, Watertown, South Dakota
I know that when I give my business to Hefty Seed Company, I can count on great yields from their products and outstanding service from their knowledgeable agronomists.
Paul, Southeast South Dakota
I first tried Hefty because of the price point. Then I put four hybrids in my competition plot with four other brands of corn. Hefty took 1st, 2nd, and 3rd in my plot. That’s when I knew I was planting the real deal!
Ben, Moses Lake, Washington
I put my Hefty corn up to my favorite Pioneer and Dekalb, and wow does it perform! I’ll keep planting Hefty!
Luke, Iowa
The emergence and yields I have gotten from my Hefty Brand Seed have been outstanding!
Mark, Southeast South Dakota
I plant corn for Habitat for Hunting. My ground is really tough due to flooding it each year. I switched to Hefty Corn because of how well it handles tough, dry soil.
Mike, Othellow, Washington
Out of everything I planted, Hefty has always been the first corn out of the ground over the last three years.
