The '''field pea''' is a type of pea sometimes called ''P. sativum'' subsp. ''arvense'' (L.) Asch.  It is also known as dun (grey-brown) pea, Kapucijner pea, or Austrian winter pea, and is one of the oldest domesticated crops, cultivated for at least 7,000 years.  Field peas are now grown in many countries for both human consumption and stockfeed.  There are several cultivars and colors including blue, dun (brown), maple and white. This pea should not be confused with the [[cowpea]] (''Vigna unguiculata'') which is sometimes called the "field pea" in warmer climates.<ref>{{cite web|title=Field pea, (Pisum sativum)|url=http://www.pulseaus.com.au/Fieldpea.aspx|publisher=Pulse Australia|access-date=2019-04-11|archive-url=https://web.archive.org/web/20131104115649/http://www.pulseaus.com.au/Fieldpea.aspx|archive-date=2013-11-04|url-status=dead}}</ref><ref>{{cite web|last=French|first=Bob|title=Crop management Growing field pea|url=http://www.agric.wa.gov.au/objtwr/imported_assets/content/fcp/lp/southern_pulse_manual_ch2.pdf|publisher=Australia, Dept. of Agriculture and Food|access-date=11 April 2019|archive-date=3 April 2015|archive-url=https://web.archive.org/web/20150403092440/https://www.agric.wa.gov.au/objtwr/imported_assets/content/fcp/lp/southern_pulse_manual_ch2.pdf|url-status=dead}}</ref>

It is a climbing annual legume with weak, viny, and relatively succulent stems. Vines often are 4 to 5 feet (120 to 150&nbsp;cm) long, but when grown alone, field pea's weak stems prevent it from growing more than 1.5 to 2 feet (45 to 60&nbsp;cm) tall. Leaves have two leaflets and a tendril. Flowers are white, pink, or purple. Pods carry seeds that are large (4,000 seeds/lb), nearly spherical, and white, gray, green, or brown. The root system is relatively shallow and small, but well nodulated.<ref>{{cite web|last=Sattell|first=R|title=Field Pea|url=http://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/15224/em8698.pdf|publisher=Oregon State U.}}</ref>

The field pea is a cool-season legume crop that is grown on over 25 million acres worldwide. It has been an important [[grain legume]] crop for millennia, seeds showing domesticated characteristics dating from at least 7,000 years ago have been found in archaeological sites around what is now [[Turkey]].  Field peas or "dry peas" are marketed as a dry, shelled product for either human or [[livestock]] food, unlike the garden pea, which is marketed as a fresh or canned vegetable. The major producing countries of field peas are Russia and China, followed by Canada, Europe, Australia and the United States. Europe, Australia, Canada and the U.S. raise over 4.5 million acres (18,000 km²) and are major exporters of peas. In 2002, there were approximately 300,000 acres (1,200 km²) of field peas grown in the U.S.<ref>{{cite web|last=McKay|first=Kent|title=Field Pea Production|url=http://www.ndsu.edu/pubweb/pulse-info/resources-pdf/Fieldpea%20production%20guide.pdf|publisher=North Dakota State University|access-date=11 April 2019|archive-date=10 October 2019|archive-url=https://web.archive.org/web/20191010235504/https://www.ndsu.edu/pubweb/pulse-info/resources-pdf/Fieldpea%20production%20guide.pdf|url-status=dead}}</ref>
