Chicago Board of Trade corn futures ended firm on Friday as concerns about a larger-than-anticipated US harvest only partly offset spillover support from higher soy amid easing US-China trade tensions, traders said. CBOT December corn settled up 1-1/2 cents at $3.68-3/4 per bushel. The contract held chart support at its 20-day moving average.

December corn ended the week up 3.7%, the contract's steepest weekly gain in two months. September corn futures expired on Friday at $3.55-1/2 per bushel. Soyabean futures extended gains on signs of easing trade tensions between the United States and China and the resumption of soyabean purchases by Chinese importers. Rising soy prices buoyed corn futures.

Corn remained anchored by large supplies after the US Department of Agriculture (USDA) on Thursday raised its 2019 harvest outlook The USDA cut its US corn production estimate to 13.799 billion bushels, from 13.901 billion last month.
