Nope. I think we're going to have a friendly agreement that you guys are wrong that say tw makes no yield difference.

Tim, you say that the farmer might have to just haul another truckload of the light corn. Well, if the kernels are the same size, then that won't happen. The field will only have so many corn kernels in it regardless of tw. Everyone knows this when they do their yield computations in the early fall. They count the kernels on one ear & multiply it by the population. That's all the kernels there are. You can't go find any more. If the kernels fill a 41' hopper bottom up to the ledge, he'll have 50,000# of grain assuming a certain bulk density (=TW) of the kernels, a given amount of kernels (kernels per ear x population). If the kernels are more dense (= higher tw), that same physical size load of the same # of kernels is going to be heavier. Instead of 50,000# of corn, he might have 51,000# of grain off that same field (let's assume this is all the grain from that given field). You now have a higher yield. There was no more corn. Also, if that corn had a lower bulk density (=tw), then the "full to the brim" load might only weigh 48,000#. Again, there is no more grain to go get.

Finally, no, I don't say that higher t.w. always = higher yield. But, an explainably low tw of any variety will usually mean an unexplainable lower yield.
