IL | I guess I'm not sure why there would be any reasons other than Mother Nature. We've discussed this before about beans, and corn is the same story. If you're looking for a so-called yield drag, it just isn't there. Average yields have always fluctuated up & down wildly depending on the season. In fact, if you look at yields over the past ten years or so, they've actually fluctuated less (and remained at or near record levels) since the introduction of GMO's. Not saying that GMO's are the reason for that (although they could play a part), but you certainly can't show any yield drag. A given genetics (and accompanying traits) will respond different each year because the conditions each year are different. That is going to continue until someone finds a working crystal ball & magic wand. | |
