WASHINGTON, June 29 (UPI) -- Progress in the U.S. corn crop remains far behind its historic average, as the corn cobs enter the silking stage, the U.S. Department of Agriculture said.
In the previous five seasons, the 18 largest corn-producing states have averaged 8 percent of the crop at the silking stage by this time of year. Only 4 percent of this year's crop has reached that stage so far this year.
