73-617: A bean is the seed of any plant in the legume family ( Fabaceae ) used as a vegetable for human consumption or animal feed. The seeds are often preserved through drying , but fresh beans are also sold. Most beans are traditionally soaked and boiled, but they can be cooked in many different ways, including frying and baking, and are used in many traditional dishes throughout the world. The unripe seedpods of some varieties are also eaten whole as green beans or edamame (immature soybean ), but fully ripened beans contain toxins like phytohemagglutinin and require cooking. The word 'bean', for

Archaeological evidence suggests that these peas must have been grown in the eastern Mediterranean and Mesopotamian regions at least 5,000 years ago and in Britain as early as the 11th century. The soybean was domesticated around 5,000 years ago in China from a descendant of the wild vine Glycine soja. The oldest-known domesticated beans in
219-507: A botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Most legumes have symbiotic nitrogen-fixing bacteria in structures called root nodules . Some of the fixed nitrogen becomes available to later crops, so legumes play a key role in crop rotation . The term pulse , as used by the United Nations' Food and Agriculture Organization (FAO),
292-511: A certain cost must include artwork. KORO , the Norwegian State agency overseeing art in public spaces, engaged the artist to propose an artwork for the Seed Vault. The roof and vault entrance are filled with highly reflective stainless steel, mirrors, and prisms. The installation reflects polar light in the summer months, while in the winter, a network of 200 fibre-optic cables gives the piece
365-413: A diet of perennial grasses. Factors include larger consumption, faster digestion, and higher feed conversion rate . The type of crop grown for animal rearing depends on the farming system. In cattle rearing, legume trees such as Gliricidia sepium can be planted along edges of fields to provide shade for cattle, the leaves and bark are often eaten by cattle. Green manure can be grown between harvesting
438-590: A history of destroying some genebanks. The national genebank of the Philippines was damaged by flooding and later destroyed by a fire, the genebanks of Afghanistan and Iraq have been lost completely, while an international genebank in Syria became unavailable. According to The Economist , "the Svalbard vault is a backup for the world's 1,750 seed banks, storehouses of agricultural biodiversity ." Norwegian law has prohibited

Guar beans are used for their gum , a galactomannan polysaccharide . It is used to thicken and stabilise foods and other products. Some kinds of raw beans contain a harmful, flavourless toxin: the lectin phytohaemagglutinin , which must be destroyed by cooking. Red kidney beans are particularly toxic, but other types also pose risks of food poisoning . Even small quantities (4 or 5 raw beans) may cause severe stomachache, vomiting, and diarrhea. This risk does not apply to canned beans because they have already been cooked. A recommended method
730-507: A muted greenish-turquoise and white light. The Seed Vault's mission is to provide a backup against accidental loss of diversity in traditional genebanks. While the popular press has emphasized its possible utility in the event of a major regional or global catastrophe, the Seed Vault will be more frequently accessed when genebanks lose samples due to mismanagement, accident, equipment failures, funding cuts, and natural disasters . These events occur with some regularity. War and civil strife have

#1732858445132876-1557: A serious pest to broad beans and other beans. Common hosts for this pest are fathen, thistle and dock. Pea weevil and bean weevil damage leaf margins leaving characteristics semi-circular notches. Stem nematodes are very widespread but will be found more frequently in areas where host plants are grown. Common legume diseases include anthracnose , caused by Colletotrichum trifolii ; common leaf spot caused by Pseudomonas syringae pv. syringae ; crown wart caused by Physoderma alfalfae ; downy mildew caused by Peronospora trifoliorum ; fusarium root rot caused by Fusarium spp.; rust caused by Uromyces striatus ; sclerotina crown and stem rot caused by Sclerotinia trifoliorum ; Southern blight caused by Sclerotium rolfsii ; pythium (browning) root rot caused by Pythium spp.; fusarium wilt caused by Fusarium oxysporum ; root knot caused by Meloidogyne hapla . These are all classified as biotic problems. Abiotic problems include nutrient deficiencies, (nitrogen, phosphorus, potassium, copper, magnesium, manganese, boron, zinc), pollutants (air, water, soil, pesticide injury, fertilizer burn), toxic concentration of minerals, and unfavorable growth conditions. Seed viability decreases with longer storage time. Studies done on vetch , broad beans , and peas show that they last about 5 years in storage. Environmental factors that are important in influencing germination are relative humidity and temperature. Two rules apply to moisture content between 5 and 14 percent:
949-910: A significant source of protein , dietary fibre , carbohydrates , and dietary minerals ; for example, a 100 gram serving of cooked chickpeas contains 18 percent of the Daily Value (DV) for protein, 30 percent DV for dietary fiber, 43 percent DV for folate and 52 percent DV for manganese . Legumes are an excellent source of resistant starch ; this is broken down by bacteria in the large intestine to produce short-chain fatty acids (such as butyrate ) used by intestinal cells for food energy . Forage legumes are of two broad types. Some, like alfalfa , clover , vetch ( Vicia ), stylo ( Stylosanthes ), or Arachis , are sown in pasture and grazed by livestock. Others, such as Leucaena or Albizia , are woody shrubs or trees that are either broken down by livestock or regularly cut by humans to provide fodder. Legume-based feeds improve animal performance over
1022-540: A small number of the most productive varieties. Efforts are being made to conserve the germplasm of older varieties in different countries. As of 2023, the Norwegian Svalbard Global Seed Vault holds more than 40,000 accessions of Phaseolus bean species. Unlike the closely related pea , beans are a summer crop that needs warm temperatures to grow. Legumes are capable of nitrogen fixation and hence need less fertiliser than most plants. Maturity

Cooking beans, without bringing them to a boil, in a slow cooker at a temperature well below boiling may not destroy toxins. A case of poisoning by butter beans used to make falafel was reported; the beans were used instead of traditional broad beans or chickpeas , soaked and ground without boiling, made into patties, and shallow fried . Bean poisoning

Many beans are vines needing external support, such as "bean cages" or poles. Native Americans customarily grew them along with corn and squash, the tall stalks acting as support for the beans. More recently, the commercial "bush bean" which does not require support and produces all its pods simultaneously has been developed. The production data for legumes are published by FAO in three categories: The following
