Estimating crop yields before harvest can be variable, but producers often like to know about the potential yield of their crops. As the sorghum crop gets closer to full maturity, yield estimates will be more accurate because the seed weight will be closer to being set.
Every year, the National Wheat Foundation promotes a National Wheat Yield Contest, with winners coming from many states, and often from Kansas. Entering is easy and must be done by May 15 for winter wheat, although you are encouraged to enter by April 15 to get into an early entry prize drawing.
