NEW YORK (AP) — Corn is rising the most in more than a month after the government reported that farmers left a large amount of land unplanted, which could lead to lower supplies.

The price of corn rose after the government reported good demand for the crop and forecasts called for dry weather in the growing region.

Corn prices have been falling all summer on expectations of a strong crop.

Corn futures for December delivery rose 17 cents, or 3.7 percent, to $4.72 a bushel, its biggest increase since July 9.

Wheat and soybean prices also rose.

In metals trading, the price of silver jumped for a sixth consecutive day. Gold also climbed. Copper fell.

In energy trading, the price of oil rose 48 cents, or 0.4 percent, to $107.33 a barrel.
