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.
The following are international Maize (corn) production statistics come from the Food and Agriculture Organization figures from FAOSTAT statics 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 ...
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]

The Pro Farmer Crop Tour found ideal growing conditions could supercharge Iowa's corn yield
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)
Finally in the 1950s, new mechanical harvesters allowed a handful of workers to pick as much as 100 had done before. The result was a large-scale exodus of the white and black cotton farmers from the south. By the 1970s, most cotton was grown in large automated farms in the Southwest. [119] [120]
Since the 1970s, Willett and a team at Harvard have been studying types of dietary fat, tracking over 200,000 people for more than four decades to monitor the impact of nutrition on the incidence ...
