CBOT corn ends flat on technicals, short-covering

CHICAGO: Chicago Board of Trade corn futures ended roughly unchanged on Monday as pressure from ample global grain supplies and favorable US weather was offset by technical support, traders said.

Corn rebounded from Friday's 21-month lows but there was little new buying amid overall favorable US growing conditions and expectations for a big harvest in the United States.

Analysts polled by Reuters expected the US Department of Agriculture later on Monday to slightly lower US corn crop condition ratings.
