Corn development and yield: Updated forecasts available for the Corn Belt

by Jeff Coulter, Extension Corn Specialist

Much of the corn in Minnesota is in the dough stage of kernel development. Once kernels enter the dough stage, about four weeks after tassel emergence, kernel number is established and yield loss caused by stress is due to a reduction in kernel size.

To evaluate the impact of this season’s weather on corn yield potential and its spatial variability across the Corn Belt, including three locations in Minnesota, yield forecasts were made on August 10 by University of Nebraska researchers as part of a multi-state project: http://cropwatch.unl.edu/2016/2016-corn-yield-forecasts-aug-10

Updated forecasts of corn yield and development are planned for late August.
