CHICAGO, Sept. 7 (UPI) -- Grain futures closed mixed Friday on the Chicago Board of Trade with the dollar index off 1.17 percent to 80.17 on the International Exchange.

Corn was off 2 1/4 to up 1 1/2, soybeans were off 10 to off 12 3/4, wheat was up 10 1/4 to up 13 1/4 and oats were off 1/2 to up 1.

Corn futures were flat Friday as a market analyst estimated the corn yield for the year at 119.8 bushels per acre compared to an earlier estimate of 120.7. The wheat market gained mostly on the weaker dollar, while soybean futures dropped in double digit figures, although the major direction decisions will come after the U.S. Federal Reserve's policy decision expected on Thursday.
