Fast emerger with big yield potential! Nice flex and girthy ears with very good drydown. Strong stalks and roots work well across a wide variety of stressful environments.


Shorter plant may not be the best for silage.


This is a really good hybrid that stretches west into Montana and North Dakota and also works in areas where it rains more. The best fit is in the normal 80-85 day maturity zone in average ground to better soils. It’s a shorter hybrid, so avoid the toughest ground. Showed good strength in the Red River Valley. H3302 will be tough to beat running west, but this one shares the same female in the cross and should do well.

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!

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

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 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.

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.
