The US is the world's largest producer of corn. [8] According to the United States Department of Agriculture (USDA), the average U.S. yield for corn was 177 bushels per acre, up 3.3 percent over 2020 and a record high, with 16 states posting state records in output, and Iowa reporting a record of 205 bushels of corn per acre.
Over time, the stalks will decrease in value as feed, so farmers aim to graze the corn stover as soon as possible after harvest. The amount of grazing possible on a field of corn stover is "between one and two months of grazing per cow per acre (50 cows on 50 acres (200,000 m 2) for one to two months)." [5]

The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution .
