. Retrieved October 16, 2015, Peanuts need warm weather throughout the growing season to develop well. They can be grown with as little as of water, but for best yields need at least . Depending on growing conditions and the cultivar of peanut, harvest is usually 90 to 130 days after planting for subspecies ''A. h. fastigiata'' types, and 120 to 150 days after planting for subspecies ''A. h. hypogaea'' types. Subspecies ''A. h. hypogaea'' types yield more and are usually preferred where the growing seasons are sufficiently long. Peanut plants continue to produce flowers when pods are developing; therefore, some pods are immature even when they are ready for harvest. To maximize yield, the timing of harvest is important. If it is too early, too many pods will be unripe; if too late, the pods will snap off at the stalk and remain in the soil. For harvesting, the entire plant, including most of the roots, is removed from the soil. The pods are covered with a network of raised veins and are constricted between seeds. The main yield-limiting factors in semiarid regions are drought and high-temperature stress. The stages of reproductive development before flowering, at flowering, and at early pod development are particularly sensitive to these constraints. Apart from

. Biotic stresses mainly include pests, diseases, and weeds. Among insects pests, pod borers, aphids, and mites are of importance. The most important diseases are leaf spots, rusts, and the toxin-producing fungus Aspergillus. Harvesting occurs in two stages. In mechanized systems, a machine is used to cut off the main root of the peanut plant by cutting through the soil just below the level of the peanut pods. The machine lifts the "bush" from the ground, shakes it, then inverts it, leaving the plant upside down to keep the peanuts out of the soil. This allows the peanuts to dry slowly to a little less than a third of their original moisture level over three to four days. Traditionally, peanuts were pulled and inverted by hand. After the peanuts have dried sufficiently, they are threshed, removing the peanut pods from the rest of the bush. peanuts must be dried properly and stored in dry conditions. If they are too high in moisture, or if storage conditions are poor, they may become infected by the

The small Spanish types are grown in South Africa and the southwestern and southeastern United States. Until 1940, 90% of the peanuts grown in the US state of Georgia were Spanish types, but the trend since then has been larger-seeded, higher-yielding, more

-resistant cultivars. Spanish peanuts have a higher oil content than other types of peanuts. In the United States, the Spanish group is primarily grown in New Mexico, Oklahoma, and Texas. Cultivars of the Spanish group include 'Dixie Spanish,' 'Improved Spanish 2B', 'GFA Spanish,' 'Argentine,' 'Spantex,' 'Spanette,' 'Shaffers Spanish,' 'Natal Common (Spanish),' "White Kernel Varieties,' 'Starr,' 'Comet,' 'Florispan,' 'Spanhoma,' 'Spancross,' 'OLin,' 'Tamspan 90', 'AT 9899–14', 'Spanco,' 'Wilco I,' 'GG 2', 'GG 4', 'TMV 2', and 'Tamnut 06'.

Runner group

Since 1940, the southeastern US region has seen a shift to producing Runner group peanuts. This shift is due to good flavor, better roasting characteristics, and higher yields when compared to Spanish types, leading to food manufacturers' preference for the use in peanut butter and salted nuts. Georgia's production is now almost 100% Runner-type. Cultivars of Runners include 'Southeastern Runner 56-15', 'Dixie Runner,' 'Early Runner,' 'Virginia Bunch 67', 'Bradford Runner,' 'Egyptian Giant' (also known as 'Virginia Bunch' and 'Giant'), 'Rhodesian Spanish Bunch' (Valencia and Virginia Bunch), 'North Carolina Runner 56-15', 'Florunner,' 'Virugard,' 'Georgia Green,' 'Tamrun 96', 'Flavor Runner 458', 'Tamrun OL01', 'Tamrun OL02' 'AT-120', 'Andru-93', 'Southern Runner,' 'AT1-1', 'Georgia Brown,' 'GK-7', and 'AT-108'.

Virginia group

The large-seeded Virginia group peanuts are grown in the US states of Virginia, North Carolina, Tennessee, Texas, New Mexico, Oklahoma, and parts of Georgia. They are increasing in popularity due to the demand for large peanuts for processing, particularly for salting, confections, and roasting in shells. Virginia group peanuts are either bunch or running in growth habit. The bunch type is upright to spreading. It attains a height of , and a spread of , with rows that seldom cover the ground. The pods are borne within of the base of the plant. Cultivars of Virginia-type peanuts include 'NC 7', 'NC 9', 'NC 10C', 'NC-V 11', 'VA 93B', 'NC 12C', 'VA-C 92R', 'Gregory,' 'VA 98R', 'Perry,' 'Wilson, 'Hull,' 'AT VC-2' and 'Shulamit.'

, which is generally fatal if untreated. Eating a small amount of peanuts can cause a reaction. Because of their widespread use in prepared and packaged foods, avoiding peanuts can be difficult. Reading ingredients and warnings on product packaging is necessary to avoid this allergen. Foods processed in facilities that also handle peanuts on the same equipment as other foods are required to carry such warnings on their labels. Avoiding cross-contamination with peanuts and peanut products (along with other severe allergens like shellfish) is a promoted and common practice of which chefs and restaurants worldwide are becoming aware. The

of allergy states that a lack of early childhood exposure to infectious agents like germs and parasites could be causing the increase in food allergies. Studies comparing age of peanut introduction in Great Britain with introduction in Israel showed that delaying exposure to peanuts in childhood can dramatically increase the risk of developing peanut allergies. Peanut allergy has been associated with the use of skin preparations containing peanut oil among children, but the evidence is not regarded as conclusive. Peanut allergies have also been associated with family history and intake of soy products. Some

A recent study in Canada has shown that there is no difference in the percentage of accidental exposures occurring in schools prohibiting peanuts than in schools allowing them.

However, crude (unrefined) peanut oils have been shown to contain protein, which may cause allergic reactions. In a randomized,

, 60 people with proven peanut allergy were challenged with both crude peanut oil and refined peanut oil. The authors concluded, "Crude peanut oil caused allergic reactions in 10% of allergic subjects studied and should continue to be avoided." They also stated, "Refined peanut oil does not seem to pose a risk to most people with peanut allergy." However, they point out that refined peanut oil can still pose a risk to peanut-allergic individuals if the oil that has previously been used for cooking foods containing peanuts is reused.

tests every truckload of raw peanuts for aflatoxin; any containing aflatoxin levels of more than 15 parts per billion are destroyed. The peanut industry has manufacturing steps to ensure all peanuts are inspected for aflatoxin. Peanuts tested to have high aflatoxin are used to make peanut oil where the mold can be removed.
