WASHINGTON — Key numbers in the U.S. Department of Agriculture Oct. 10 Crop Production and World Agricultural Supply and Demand Estimates reports were below the average of pre-report expectations from the trade. Still, corn and soybean futures prices declined while wheat futures posted gains after the reports were released.

U.S. 2014 corn production was forecast at 14,475 million bus, up 80 million bus from 14,395 million bus forecast in September and up 4% from 13,925 million bus in 2013. Based on Oct. 1 conditions, corn yield was forecast at 174.2 bus an acre, up 2.5 bus from September and up 15.4 bus from 158.8 bus an acre in 2013, the U.S.D.A. said. Harvested area was forecast at 83,097,000 acres, down 1% from September and down 5% from 2013.

Soybean production was forecast at 3,927 million bus, up 14 million bus from 3,913 million bus forecast in September and up 17% from an upwardly revised 3,358 million bus last year. Soybean yield was forecast at 47.1 bus an acre, up 0.5 bu from September and up 3.1 bus from an upwardly revised 44 bus an acre in 2013. Harvested area was forecast at 83,403,000 acres, down less than 1% from September but up 9% from 2013.
