SmartStax® hybrid with very strong tolerance to Goss’s and Northern Corn Leaf Blight. Good ear flex with nice response to variable-rate planting and irrigation.


Gray leaf spot tolerance is only average and will need to be addressed with a foliar fungicide at tasseling time.


Completely diverse genetics from the vaunted H6214 and H6524, this hybrid is a great addition to your SmartStax® portfolio and spreads your risk. Excellent yield potential can be reached through a balanced fertility plan with plenty of potassium in relationship to nitrogen. Expect a strong response to foliar fungicides especially at R1. Best-in-class protection from Goss’s wilt is a nice feature, as well.


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.

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 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!

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

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.
