A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. [1] They are also considered centers of diversity. Centers of origin were first identified in 1924 by Nikolai Vavilov.
However Harlan preferred the term center of diversity to Vavilov's term center of origin, because while the centers of crop diversity are known and mapped, the origins of crops cannot be definitely pinned down. In The Living Fields: Our Agricultural Heritage he wrote: First, we will not and cannot find a time or place where agriculture originated.
In 1982, the American conceptual artist Agnes Denes grew a two-acre field of wheat at Battery Park, Manhattan. The ephemeral artwork has been described as an act of protest. The harvested wheat was divided and sent to 28 world cities for an exhibition entitled "The International Art Show for the End of World Hunger". [201]
Nikolai Ivanovich Vavilov ForMemRS, [3] HFRSE (Russian: Никола́й Ива́нович Вави́лов, IPA: [nʲɪkɐˈlaj ɪˈvanəvʲɪtɕ vɐˈvʲiləf] ⓘ; 25 November [O.S. 13 November] 1887 – 26 January 1943) was a Russian and Soviet agronomist, botanist and geneticist who identified the centers of origin of cultivated plants.
Agricultural history took a different path from the Old World as the Americas lacked large-seeded, easily domesticated grains (such as wheat and barley) and large domestic animals that could be used for agricultural labor. Rather than the practice which developed in the Old World of sowing a field with a single crop, pre-historic American ...
During the first decade of the 2000s, wheat ranked third among U.S. field crops in both planted acreage and gross farm income; the first two positions were held by corn and soybeans. The acreage has gone down by nearly 30% (to 48,653,000 acres in 2001, as against 60-63 million acres harvested annually in the previous years; 30 of this area is ...
In 1988, the Israeli botanist Daniel Zohary and the German botanist Maria Hopf formulated their founder crops hypothesis. They proposed that eight plant species were domesticated by early Neolithic farming communities in Southwest Asia (Fertile Crescent) and went on to form the basis of agricultural economies across much of Eurasia, including Southwest Asia, South Asia, Europe, and North ...
