The price for the protein-rich bean hit an all-time high of $17.7025 per bushel in late August on concerns that the drought had damaged the crop. But early harvest reports show yields have been better than expected and overall demand remains strong.
The U.S. Agriculture Department said 41 percent of the crop had been harvested by Sunday, compared with an average of 19 percent over the previous four years.
