Hefty 4322 and 4612 corn is very versatile and fit on all of my acres.

Mike, Pope County, Minnesota

Hefty 4322 is a very fast germinating corn crop.

Dave, Eastern South Dakota

Hefty 4322 and 4612 make a nice combination in my fields. Both have some height so they can dual purpose for silage on any soil type.

Ron, Pope County, Minnesota

Hefty 4322 will go on peat soils because it is quick out of the ground and it has some height so it is versatile for a silage option.

Mike, Stearns County, Minnesota

Hefty 4322 comes out of the ground quick and it stands well in heavy winds on my hilly ground.

Brad, Pope County, Minnesota

Hefty 4322 stood intact way better and yielded 20 bushels better than the NK hybrid in my field.
