KEY STRENGTHS
Big plant with very strong yield data! Ear flexes well for length. Heavy test weigh! Fast drydown.

WEAKNESSES
Staygreen and Goss’s tolerance are just average.

POSITIONING
The best fit is in zone for maturity and slightly south, as well. The Goss’s tolerance suggests placement 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.

AGRONOMIC & DISEASE RATINGS

H4564 Agronomic Chart

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

Luke, Iowa

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

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

Devon, Southeast Nebraska

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!
