ST. LOUIS (AP) — A deepening drought in the nation's farm states has cut further into this fall's harvest, with farmers now expected to pull from their fields the lowest corn yield in more than a decade. But American farmers are still expected to produce their eighth-largest harvest ever, and while there's sure to be a rise in prices at the grocery stores, there's little risk of a failed harvest that would lead to shortages on the shelves. The U.S. Agriculture Department predicted the nation's biggest harvest ever in the spring, when farmers planted 96.4 million acres of corn — the most since 1937.
