When you look at Central Illinois you run into a lot of fields that have an average PI of 130-145. Obviously there are always some above and below that but generally a lot fall in the 130-145 range. These are fields that probably have APH corn yields of 220-250+. We are in southwest Illinois which is more variable. We farm in 4 counties adjacent to St. Louis and land in our area ranges generally between 100 to 135 in terms of average PI. Generally the area closest to St. Louis is the most productive then it tails off as you head east. When you get to Mt. Vernon and points east you will likely find a lot of field average PI in the 90-100 range. I don't know what the worst average PI field in Illinois would be but I am guessing you would be hard pressed to find many fields under 85. So it is really not a wide range and the difference between a field with a PI of 100 and one at 130 is pretty big. That being said the new corn hybrids have benefited the lower PI ground more than the higher PI ground just because it seems to deal with stress better.
