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.
Heavily mechanized, U.S. agriculture has a high yield relative to other countries. As of 2004: [20] Corn for grain, average of 160.4 bushels harvested per acre (10.07 t/ha) Soybean for beans, average of 42.5 bushels harvested per acre (2.86 t/ha) Wheat, average of 43.2 bushels harvested per acre (2.91 t/ha, was 44.2 bu/ac or 2.97 t/ha in 2003)
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]

Yield mapping or yield monitoring is a technique in agriculture of using GPS data to analyze variables such as crop yield and moisture content in a given field. It was developed in the 1990s and uses a combination of GPS technology and physical sensors, such as speedometers , to track crop yields, grain elevator speed, and combine speed.
Along with climate and corresponding types of vegetation, the economy of a nation also influences the level of agricultural production. Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat.
