KEY STRENGTHS

Dominating yielder! Roundup Ready® version of the popular H3712 hybrid with powerful yield! Strong push out of the ground in the spring. Handles most soil types very well.

WEAKNESSES

No Bt insect protection.

POSITIONING

Girthy ears with 18-20 kernels around! Push this one with fertility near the row at planting time. Root system is adequate but can be greatly enhanced with practices such as in-furrow microbials like Alpha Complete and protection from insecticide like Capture LFR.

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 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

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 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

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

Mark, Southeast South Dakota

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.
