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.
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]
Research on plant breeding produced varieties of grain crops that could produce high yields with heavy fertilizer input. This resulted in the Green revolution, beginning in the 1940s. [99] By 2000 yields of corn (maize) had risen by a factor of over four. Wheat and soybean yields also rose significantly. [100] [101]
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer , the creation of better farming tools, new methods of farming and improved crop varieties , have ...
The Pro Farmer Crop Tour found ideal growing conditions could supercharge Iowa's corn yield
6001 BC – Archaeological evidence from various sites on the Iberian Peninsula suggest the domestication of plants and animals. 6000 BC – Granary built in Mehrgarh for storage of excess food. 5500 BC – Céide Fields in Ireland are the oldest known field systems in the world, this landscape consists of extensive tracts of land enclosed by ...
The middle plot was originally planted in a rotation of corn and oats, with the oats replaced by soybeans in 1968. The southern plot was originally planted in a rotation of two years of corn, one year of oats, and three years clover; this was replaced in 1901 by a rotation of corn, oats, and clover, and in 1953 by corn, oats, and alfalfa.
