Six percent more potatoes than last year were planted for fall harvests, according to a new U.S. Department of Agriculture report.

About 949,000 acres of potatoes were planted by U.S. growers, up from 894,000 acres for Fall 2010 harvests, according to the USDA’s National Agricultural Statistics Service’s latest Crop Production report.

About 320,000 acres were planted in industry leader Idaho, 8% more than in 2010.

An even bigger percentage increase is expected from industry No. 2 Washington. Acreage there is projected to rise from 135,000 to 155,000, or 15%.

Acreage in the fourth-largest producing state, Wisconsin, is expected to increase slightly, from 62,500 to 63,000 acres.

Fall acreage in Maine, Michigan, Minnesota and Oregon is expected to increase in 2011.
