CHICAGO: Chicago Board of Trade corn futures declined on Friday on expectations of active harvesting in the Corn Belt this weekend and investor uncertainty after US President Trump tested positive for the novel coronavirus, rattling global financial markets.

CBOT December corn settled down 3 cents at $3.79-3/4 per bushel. Private analytics firm IHS Markit on Friday cut its forecast of the average US 2020 corn yield to 177.8 bushels per acre (bpa), from 178.1 a month ago.
