Gamechanger! Emergence and early vigor are off the charts, and it closes the rows quickly. Top-end yielder!


Average tolerance to Goss’s wilt and gray leaf spot.


This is a hybrid to fall in love with quickly as it responds to fertility, increased population, and in-furrow applications of microbial products like Alpha Complete. It has the ability to put on sizable tillers to feed the plant late in the season more reliably than the roots can. Use a fungicide for gray leaf spot protection mid to late season.

H4933 was one of the first hybrids that emerged on my farm.

Steve, Southwest Minnesota

Hefty 4933 is good on my high fertility ground.. The emergence looks excellent and responds well where manure was applied.

John, Swift County, Minnesota

Hefty 4933 has the top end yield for my high fertility manured ground and my marginal soils it has the drought tolerance and defense.

Justin, Big Stone County, Minnesota

Hefty 4933 corn looks like a fit in the 97 to 99-day offerings that yield with the best 100’s.

Jon, Stevens County, Minnesota

Hefty 4933 handles my variable soils well. It has extra top end on the heavy soils and shows off the DroughtGard® on sandy ground.
