As well as the northern corn belt, there also has been research in Texas and some of the dry areas of the US where quicker canopy shows some water savings and better yield. I think that is where we get the yield bump from. Our long term average is about 125 bpa to give you an idea of yield levels. Best ever whole farm average one year was almost 150. Worst was about 30. Highest individual field around 200. Our yields do vary.
