Home run hitter! Explosive yields across high and low productivity fields. Callouts include staygreen, late season intactness, and Goss’s and gray leaf spot tolerance.


Northern corn leaf blight tolerance is average.


This hybrid will flex for length and responds well to increased soil and applied fertility. Fungicide response is average, but improves greatly if northern corn leaf blight protection is needed. Planting time insecticide is recommended in areas of the country with moderate levels of rootworm or other soil insect pressure.

My Hefty Brand Corn (including H4522)  has done well for me over the past couple of years, so I continue to plant it.

Gaylen, Southwest Minnesota

Hefty Corn (H4522) looks good on my farm all season long and outperforms the competition.

Paul, Willmar, Minnesota

Hefty 4522 is taller and darker green than the competitor variety through the entire field.

Levi, Fall River County, South Dakota

H4522 looks like a yield monster starting at emergence. This number has a very dark green color and came out of the ground faster than the others.

John, Canby, Minnesota

Hefty 4522 is great looking corn in the field.

Jeremy, Central South Dakota

The Hefty Corn emergence was great this year and we’re expecting excellent yield.
