Excellent test weight and great yield potential in good soils! Responds well to higher plant populations and higher fertility levels.


Less ear flex than other Hefty Brand hybrids. A little less staygreen in the fall, so it should move up a little in your harvest order.


Loves the Red River Valley and east into Minnesota. This hybrid has a little less ear flex than others in the lineup and requires a little more population to fully express its yield. Responds very well to fertility, beneficial microbials, and intensive management.

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

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!

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.

I put my Hefty corn up to my favorite Pioneer and Dekalb, and wow does it perform! I’ll keep planting Hefty!

Luke, Iowa

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.

The emergence and yields I have gotten from my Hefty Brand Seed have been outstanding!

Out of everything I planted, Hefty has always been the first corn out of the ground over the last three years.
