CHICAGO- Chicago corn futures ticked down and soybean futures hovered near unchanged on Friday with seasonal harvest pressure on the rise.

Meanwhile, wheat futures notched up on dryness in some wheat-producing regions of the world, analysts said.

The most-active corn contract on the Chicago Board of Trade (CBOT) settled down 4 cents at $4.01-3/4 a bushel. For the week, it fell 1.81 percent .

Soybeans ended down $1-1/4 at $10.12 per bushel, with a weekly rise of 0.57 percent .

Most-active wheat contracts rose 3 cents to end at $5.68-1/2 per bushel, with a weekly drop of 4.91 percent .

Wheat rose with worries about dryness in the Black Sea, the US Southern Plains and Argentina, said Arlan Suderman, chief Commodities Economist for the StoneX group.

Suderman said he was “expecting to see more tightness in major exporting supplies, particularly as we get into the last half of the marketing year.”
