Stress tolerant, high-yielding hybrid! Strong Goss’s tolerance and excellent test weight. Great greensnap scores as well. SmartStax® version of H5522.


Ear type has a little less flex and a medium-high population is preferred.


Keep the populations up over 25,000 in the stress zones and pour the coals to this hybrid with population, fertility, and foliar fungicides in the high-yielding ground. Excellent low-end yield stability with great upside, as well.


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

I have been pleased with the very consistent yield performance in Hefty 5524.

Great emergence on Hefty 5524 with the seed treatment!

Hefty 5524 and the rest of the corn have been very solid the past few years so we have gone to most of the farm being Hefty Brand Seed.

After buying Hefty Corn 5524, the average yields on my corn last year were impressive. I’ve been getting good yields after switching to Hefty Brand Corn.

Hefty Corn 5524 was a phenomenal yielder and packed a great punch during harvest!

Jim, Southeast South Dakota

Hefty 5524 was planted on sod and we were concerned about emergence, but I think every kernel grew; it looks really good!
