Domestication of Plants in the Americas: Insights
... Helianthus annuus (sunflower) were also domesticated for
their oil-rich seeds. The first sign of domestication in all
three is the appearance of large seeds or fruits, outside
the range of modern wild forms (Smith, 2006). Cucurbita
pepo and sunflower are still important crops, but marshelder
had dis ...
... Such is the aim of this book which, beginning with an analysis of the
characteristics of these plants, attempts to identify possible areas of research
and development in order to facilitate, where possible, their reintroduction
in regions to which they had become so well adapted over the centuries. ...
The Biology of Hordeum vulgare L. (barley)
... barley comes from more southern areas, such as South Australia and Victoria, due to climatic
conditions (Sims 1990).
Traditionally, barley was one of the dominant food grains, but has been surpassed by rice and
wheat in many countries. Barley is still an important food grain in several re ...
History of agriculture
Agriculture involving domestication of plants was developed around 11,500 years ago separately in both the Fertile crescent and at Chogha Golan in modern day Iran, where wild barley, wheat, and lentils were cultivated and with domesticated forms of wheat appeared about 9,800 years ago. Agriculture has undergone significant developments since the time of the earliest cultivation. The Fertile Crescent of Western Asia, Egypt and India were sites of the earliest planned sowing and harvesting of plants that had previously been gathered in the wild. Independent development of agriculture occurred in northern and southern China, Africa's Sahel, New Guinea, parts of India and several regions of the Americas. Agricultural techniques such as irrigation, crop rotation, the application of fertilizers were developed soon after the Neolithic Revolution but have made significant strides in the past 200 years. The Haber-Bosch method for synthesizing ammonium nitrate represented a major breakthrough and allowed crop yields to overcome previous constraints.In the past century, agriculture in the developed nations, and to a lesser extent in the developing world, has been characterized by enhanced productivity, the replacement of human labor by synthetic fertilizers and pesticides, selective breeding, and mechanization. The recent history of agriculture has been closely tied with a range of political issues including water pollution, biofuels, genetically modified organisms, tariffs, and farm subsidies.
