Key Strengths
· Big plant with very strong yield data! Ear flexes well for length. Heavy test weigh! Fast drydown.
· Staygreen and Goss’s tolerance are just average. Flowers a little late for its maturity.
· The best fit is in zone for maturity and slightly south, as well. The Goss’s tolerance suggests placement from I-29 and east or in low-pressure Goss’s areas. Handles northern leaf blight well but still responds favorably to foliar fungicide applications, especially for tar spot and gray leaf spot.

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

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

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 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

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.
