Early riser! High yielding corn with outstanding early vigor. Handles stress well and works in all tillage systems. Enhanced protection from anthracnose stalk rot.


Stalks are good, but harvest timely.


air this with H5302 or H5522 to spread risk and have a phenomenal 1-2 punch! The root system on H5432 is really good, and with the high level of early vigor you can expect a strong response to in-furrow microbials like Micro-Cycle, as well as 2 X 2 or banded fertility. There is flex for girth, which will also be expressed with early fertility. Manage with foliar fungicides for disease as hybrid tolerance is average.


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 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

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

Luke, Iowa

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

Mark, Southeast 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

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