| | Agriculture - Wikipedia, the free encyclopedia |
 | | In addition to emergence of farming in the Fertile Crescent, agriculture appeared by at least 6,800 BC in East Asia (rice) and, later, in Central and South America (maize, squash). |
 | | With the rapid rise of mechanization in the 20th century, especially in the form of the tractor, the demanding tasks of sowing, harvesting and threshing could be performed with a speed and on a scale barely imaginable before. |
 | | Aquaculture, the farming of fish, shrimp, and algae, is closely associated with agriculture. |
