The '''potato''' (pl. ''potatoes''), also called ''Irish potato'' or ''white potato'' or, informally, ''spud'', is one of the world's most important [[food|foods]]. It ranks as the fourth-most-important food crop, after corn (maize), wheat and rice and ahead of soybeans. It provides more calories and more nutrients, more quickly, using less land and in a wider range of climates than any other plant. However, it is hard to store and ship long distances.

The potato is a [[tuber]] of ''Solanum tuberosum''; it comes in many colors (brown, purple, red, white, etc.) and can be easily cooked by frying in oil, baking, or boiling. For long-term storage or shipment, they can be frozen in strips (to make "French Fries" or "chips") or turned to powder.

The potato diffused widely after 1600, becoming a major food resource in Europe and East Asia. Following its introduction into China toward the end of the Ming dynasty, the potato immediately became a delicacy of the imperial family. After the middle period of the Qianlong reign (1735-96), population increases and a subsequent need to increase grain yields coupled with greater peasant geographic mobility, led to the rapid spread of potato cultivation throughout China, and it was acclimated to local natural conditions.

Sailors returning from Peru to Spain with silver presumably brought maize and potatoes for their own food on the trip. Historians speculate that leftover tubers (and maize) was carried ashore and planted.  Basque fishermen from Spain used potatoes as ships' stores for their voyages across Atlantic in the 16th century, and introduced the tuber to western Ireland, where they landed to dry their cod.

In 1588 botanist Carolus Clusius made a painting of what he called "Papas Peruanorum" from a specimen in Belgium; in 1601 he reported that potatoes were in common use in northern Italy for animal fodder and for human consumption.

The Spanish had an empire across Europe, and brought potatoes for their armies. Peasants along the way adopted the crop, which was less often pillaged by marauding armies than above-ground stores of grain. Across most of northern Europe, where open fields prevailed, potatoes were strictly confined to small garden plots because field agriculture was strictly governed by custom that prescribed seasonal rhythms for plowing, sowing, harvesting and grazing animals on fallow and stubble. This meant that potatoes were barred from large-scale cultivation because the rules allowed only grain to be planted in the open fields.<ref>William H. McNeill, "How the Potato Changed the World's History." ''Social Research'' 1999 66(1): 67-83. </ref>  In France and Germany government officials and noble landowners promoted the rapid conversion of fallow land into potato fields after 1750.

In Ireland the expansion of potato cultivation was due entirely to the landless laborers, renting tiny plots from landowners who were interested only in raising cattle or in producing grain for market. A single acre of potatoes and the milk of a single cow was enough to feed a whole Irish family a monotonous but nutritionally adequate diet for a healthy, vigorous (and desperately poor) rural population. Often even poor families grew enough extra potatoes to feed a pig which could be sold for cash.

French physician Antoine Parmentier studied the potato intensely and in ''Examen chymique des pommes de terres'' (Paris, 1774) showed their enormous  nutritional value. King [[Louis XVI]] and his court eagerly promoted the new crop, with Queen Marie Antoinette even wearing a headdress of potato flowers at a fancy dress ball. The annual potato crop of France soared to 21 million hectoliters in 1815 and 117 millions in 1840, allowing a concomitant growth in population while avoiding the Malthusian trap.  Although potatoes had become widely familiar in Russia by 1800, they were confined to garden plots until the grain failure in 1838-1839 persuaded peasants and landlords in central and northern Russia to devote their fallow fields to raising potatoes.  Potatoes yielded from two to four times more calories per acre than grain did, and eventually came to dominate the food supply in eastern Europe.  Boiled or baked potatoes were cheaper than rye bread, just as nutritious, and did not require a gristmill for grinding. On the other hand cash-oriented landlords realized that grain was much easier to ship, store and sell, so both grain and potatoes coexisted.<ref>William L. Langer, "American Foods and Europe's Population Growth 1750-1850," ''Journal of Social History,'' 8#2 (1975), pp. 51-66 </ref>

Throughout Europe the most important new food in the 19th century was the potato, which had three major advantages over other foods: its lower rate of spoilage, its bulk (which easily satisfied hunger), and its cheapness. The crop slowly spread across Europe, such that, for example, by 1845 it occupied one-third of Irish arable land. Potatoes comprised about 10% of the caloric intake of Europeans. Other foods imported from the New World included cod, sugar, rice, flour, and rum. These also provided an additional 10% of daily calories and proved a crucial factor in biodiversity of crops, thus preventing famines.<ref> John Komlos, "The New World's Contribution to Food Consumption During the Industrial Revolution."

In Britain the potato promoted economic development by underpinning the [[Industrial Revolution]] in the 19th century. As a cheap source of calories and nutrients that was easy for urban workers to cultivate on small backyard plots. Potatoes became popular in the north of England, where coal was readily available, so a potato-driven population boom provided ample workers for the new factories. Marxist [[Friedrich Engels]] even declared that the potato was the equal of iron for its "historically revolutionary role.

The Lumper potato, widely cultivated in western and southern Ireland before and during the great famine, was tasteless, wet, and poorly resistant to the potato blight, but yielded large crops and usually provided adequate calories for peasants and laborers. Heavy dependence on this potato led to disaster when the potato blight turned a newly harvested potato into a putrid mush in minutes. The [[Irish Famine]] in the western and southern parts of the British-controlled island of Ireland, 1845-49, was a catastrophic failure in the food supply that led to approximately a million deaths from famine and (especially) diseases that attacked weakened bodies, and to massive emigration to Britain, the U.S. and Canada.

Potatoes were planted in Idaho as early as 1838; by 1900 the state's production exceeded a million bushels. Prior to 1910, the crops were stored in barns or root cellars, but by the 1920s potato cellars came into use.  U.S. potato production has increased steadily; two-thirds of the crop comes from Idaho, Washington, Oregon, Colorado, and Maine, and potato growers have strengthened their position in both domestic and foreign markets.

By the 1960s, the Canadian Potato Research Centre in Fredericton, New Brunswick, was one of the top six potato research institutes in the world. Established in 1912 as a dominion experimental station, the station began in the 1930s to concentrate on breeding new varieties of disease-resistant potatoes. In the 1950s-60s the growth of the french fry industry in New Brunswick led to a focus on developing varieties for the industry. By the 1970s the station's potato research was broader than ever before, but the station and its research programs had changed, as emphasis was placed on serving industry rather than potato farmers in general. Scientists at the station even began describing their work using engineering language rather than scientific prose.<ref> Steven Turner, and Heather Molyneaux, "Agricultural Science, Potato Breeding and the Fredericton Experimental Station, 1912-66."
