Most of Chicago Board of Trade (CBOT) grains futures rallied on Wednesday following a sharp overall fall during the previous session.

The most active corn contract for December delivery rose 2.5 cents, or 0.66 percent, to 3.79 dollars per bushel. September wheat delivery went down 0.5 cent, or 0.11 percent to 4.6075 dollars per bushel. November soybeans went up 5.75 cents,or 0.59 percent, to 9.775 dollars per bushel.

CBOT brokers estimated that funds bought 3,300 contracts of soybeans, 4,000 contracts of corn, while selling 2,100 contracts of wheat.

The massive sell-offs on Tuesday had led to more than two percent fall in all grains futures, and bargain-buying on Wednesday boosted a rally, said analysts.

"It's been a choppy but mostly stronger day for the grain markets, soybeans and corn still trading higher into the close while wheat market started to tail off for the last half of the day," said Jack Scoville with the Price Futures group.
