I’ve planted Hefty Corn for the last four years and I’ll continue to plant it every year. I’ve been happy with its price and performance.

Kim, Central South Dakota

Hefty Brand Corn 3122 was priced aggressively and was the maturity I was looking for. The corn was quick out of the ground.

Stuart, Central South Dakota

The seed quality is excellent!

Steven, North Dakota

I love the planting ability of this seed (Hefty 3122) and the great emergence in lighter soil.

Greg, North Dakota

I like how Hefty Dorn pops out of the ground, usually 2-3 days sooner than the other hybrids on my farm.
