Corn fell Thursday and soybean futures rose after the government's latest crop report.
Gold and silver fell and energy futures ended higher.
Corn for December delivery fell 6.25 cents, or 1.3 percent, to $4.6625 a bushel after the U.S. Department of Agriculture reported that crop yields were higher than traders had been expecting.
