US corn futures jumped 4.5 percent on Friday on bargain buying, recouping all of the losses from a day earlier when prices fell to their lowest level in nearly a month. "There is short-covering after yesterday's big sell-off and the outside markets are commodity-friendly with the weaker dollar, higher crude oil and gains in metals," said Don Roose, president and analyst for US Commodities in Des Moines, Iowa.
At 12:29 pm CDT (1729 GMT), CBOT July corn up 27-3/4 cents at $7.57 per bushel, July wheat was up 16 cents at $7.93-1/2, and July soy up 30-1/2 cents at $13.84.
