Test plots are put on the ground that are usually somewhat good.  You wouldn't put a test plot in a water hole or the top of a sand dune.  All those areas do better and then you have higher national yield. 

 Too few of data points.

3 plots in Kansas is way to few for a state that large and so variable, without knowing where in the state those plots are it is impossible to know if the lower yield between those years was because it was too wet or too dry. 




I think this is the answer for my neck of the woods.
The test plots are put in areas where they yields are always good. However, other parts of the same fields can have dried out hills, drown out low areas, or even both.
This year, the number on my yield monitor never broke any kid of record for the highest number it read. In fact, the highest numbers it showed were probably lower than the average highest numbers I saw over the last 3-4 years.
What made the difference is that the low numbers didn't go down nearly as low as they usually do.

I have variable soils in my fields. For every acre that shows 250 on the yield monitor, I have 2 acres that show 150. This year the 250 parts of the field only showed 235-240, but the 150 parts of the field stayed above 200, making my overall average as good as it ever was. What also helped greatly in overall procuction was a dryland yield of about 165 on fields with a yield history of 7-190. It isn't very often that the dryland production is to the high end at the same time the irrigated is setting or tying overall production records, at least not here.
