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.
The combine grain yield monitor is a device coupled with other sensors to calculate and record the crop yield or grain yield as a modern-day combine harvester operates. Yield monitors are a part of the precision agriculture products available to producers today that provide producers with the tools to reduce costs, increase yields, and increase efficiency.
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. [1]
In northern Illinois, farmers could lose $140 per acre on average for corn and $30 an acre for soybeans with autumn delivery prices of $4.50 and $11.50 a bushel, respectively, the analysis showed.

For example, average yields of corn (maize) in the US have increased from around 2.5 tons per hectare (t/ha) (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001. Similarly, worldwide average wheat yields have increased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990.
