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)
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.
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 use of CMS-T, starting in the 1950s, eliminated the need for detasseling. In the early 1970s, plants containing CMS-T genetics were susceptible to southern corn leaf blight and suffered from widespread loss of yield. Since then, CMS types C and S were used instead. [7]
The study found that "the crop yields for corn and soybeans were similar in the organic animal, organic legume, and conventional farming systems". It also found that "significantly less fossil energy was expended to produce corn in the Rodale Institute's organic animal and organic legume systems than in the conventional production system. There ...
Research conducted by Indiana University's Center for Sexual Health showed that using lube makes it 50% easier for both men and women to orgasm. And it makes sense, too: according to Elist, lube ...
Since the 1960s, food production in both nations has increased faster than the rate of population growth. [citation needed] India's use of high-yield farming has prevented an estimated 100 million acres (400,000 km 2) of virgin land from being converted into farmland—an area about the size of California, or 13.6% of the total area of India.
