<<A legume in botanical writing is a plant in the family Fabaceae, or a fruit of these specific plants. A legume fruit is a simple dry fruit that develops from a simple carpel (i.e., pod) and usually dehisces (opens along a seam) on two sides. Well-known legumes include alfalfa, clover, peas, beans, lentils, lupins, mesquite, carob, soy, and peanuts. The term legume, is believed to come from the verb legere "to gather." The history of legumes is tied in closely with that of human civilization, appearing early in Asia, the Americas (the common Phaseolus bean in several varieties), and Europe (broad beans) by 6,000 BC, where they became a staple, essential for supplementing protein where there was not enough meat.
Legume plants are notable for their ability to fix atmospheric nitrogen, thanks to a symbiotic relationship with bacteria (rhizobia) found in root nodules of these plants. This fertilizer costs for farmers and gardeners, and allows legumes to be used in a crop rotation to replenish soil that has been depleted of nitrogen. Legume seed and foliage have a comparatively higher protein content than non-legume material, probably due to the additional nitrogen that legumes receive through nitrogen-fixation symbiosis. [However,] legumes contain relatively low quantities of the essential amino acid methionine. To compensate, some vegetarian cultures serve legumes along with grains, which are low in the essential amino acid lysine, which legumes contain. Thus a combination of legumes with grains can provide all necessary amino acids for vegetarians.>>
