The final estimate of corn production for the years 1950 to 1959 in the United States is given as some three billion bushels and in recent years, some nine billion bushels are produced each year. [2] Corn growth is dominated by west north central Iowa and east central Illinois. [11] In 2018, the national average production was 176 bushels 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)

Wheat yields in least developed countries since 1961, in kilograms per hectare. By one 2021 estimate, the Green Revolution increased yields by 44% between 1965 and 2010. [80] Cereal production more than doubled in developing nations between the years 1961–1985. [81] Yields of rice, corn, and wheat increased steadily during that period. [81]
Wheat production witnessed major changes in varieties and cultural practices since 1870. Thanks to these innovations, vast expanses of the wheat belt now support commercial production, and yields have resisted the negative impact of insects, diseases, and weeds.
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.
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.
