Our farm has used Hefty hybrids for at least 4 seasons and we continue to use them. We are 75% corn most years and these varieties have handled our challenging growing conditions on high pH, poorly drained soils as well as anything we have found.  The service from Jack in Watertown has been very good anytime we wanted to switch hybrids or had any issues with a specific hybrid.

Hefty 4324 has done well for me.

My Hefty Corn has yielded very well for me the past couple of years!

Armin, Southwest Minnesota

I worked closely with the guys at the Hancock location to put the right varieties on my farm. We place H4324 on corn-on-corn ground and it was very consistent across the field even through wet conditions.
