The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
The quantities of corn (maize, Zea mays) in the following table are in million metric tonnes (m STs, m LTs). All countries with a typical production quantity of at least 10 million t (11 million short tons; 9.8 million long tons) are listed below.
Wheat yields in least developed countries since 1961. The steep rise in crop yields in the U.S. began in the 1940s. The percentage of growth was fastest in the early rapid growth stage. In developing countries maize yields are still rapidly rising. [6] Productivity is driven by changes in either agricultural technique or improvements in technology.
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. Products ...
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]

Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. [79] In 2020, total world production was 1.16 billion tonnes, led by the United States with 31.0% of the total (table). China produced 22.4% of the global total. [80]
The value and production of individual crops varies substantially from year to year as prices fluctuate on the world and country markets and weather and other factors influence production. This list includes the top 50 most valuable crops and livestock products but does not necessarily include the top 50 most heavily produced crops and ...
