Beautiful hybrid with great standability and drought tolerance! Strong performer across all soil types with broad national placement. Very high test weight.


Average gray leaf spot rating.


Hybrid with national placement on all soil types. Strong drought tolerance is observed thanks to very good stalks and roots. Handles northern corn leaf blight, eye spot, and Goss’s well. Utilize fungicide applications in gray leaf spot areas. Works well in continuous corn with fungicide use.


The higher the number, the better the performance or rating.

I love the way the H4912 dries down on my farm.

Ever since switching to Hefty, my corn always looks great and the ears fill out really nice.

H4912 is excellent corn and will be planted again on our farm. Very good emergence with good dry down!

Pat, Southern Minnesota

H4912 has great dry down along with yield that handled my wetter type soil

Jerry, Southern Minnesota

I love the fast drydown of H4912.

Hefty Brand H4912 Corn had better standability than the competition in 2019. For similar yields, when compared, I would rather have standing corn with Hefty Brand Corn than worry about down crop with the competition.

For my setup, I really like the drydown of the H4912.
