Farmer Brian Pilotte holds an ear of immature corn as he looks over a drought stricken field in Idaville, Indiana, U.S., on Friday, July 6, 2012. The ear, one of the best he could find in the field, is representative of an approximately 80-90 bussel per acre yield, about half of what he would expect under normal conditions, Pilotte said. Wheat, corn and soybeans headed for the first losses in a week. Grains had surged as a heat wave in the U.S. Midwest eroded prospects for crops.
