CHICAGO: Chicago Board of Trade corn futures ended fractionally higher on Monday after a choppy session as traders squared positions a day ahead of monthly supply/demand reports due Tuesday from the US Department of Agriculture.

CBOT December corn settled up 3/4 cent at $3.57-1/2 per bushel.

Analysts surveyed by Reuters expect the government on Tuesday to trim its estimates of the US 2017 corn yield and 2017/18 US corn ending stocks.

Ahead of the USDA's weekly crop progress report due later on Monday, analysts surveyed by Reuters expected the government to report the US corn harvest as 4 percent complete.

The CBOT reported two deliveries against CBOT September corn futures contract, which expires on Thursday.
