The National Ag Statistics Service said the state's corn crop covered almost three-and-a-third million acres -- and the average yield was the second-highest on record at 156 bushels an acre.
That's about nine bushels above the national average. Wisconsin corn is eaten by both people and dairy cows, and some of it's used for making ethanol.
Officials almost 16 million tons of corn was produced for silage in 2011, almost one-and-a-half million tons more than in 2010.
Meanwhile, soybean yields in Wisconsin dropped to 46 bushels an acre. That was after a record-high of 50-and-a-half bushels the preceding year. But the state's yield was still larger than the national average of 41-and-a-half bushels per acre.
