I live in Western KS. There is now much dryland corn grown out here, where 15 years ago, you didn't see any (17-20" rainfall). In NW part, it has gotten to where many elevators will no longer take grain sorghum, since they can fill up with corn which is more consistent in grade, moisture, etc. Have some neighbors who grow 1000-1500 ac. per year. They started in 1989, and have a 92 bushel average over the 10 years. They expect some 120 bushel corn this year, with a wet summer. Many acres of dryland soybeans now grown also.
