Daikon 大根 (だいこん) or mooli, (مولی) Radish var. longipinnatus, is a mild-flavored winter radish usually characterized by fast-growing leaves and a long, white, root. Originally native to continental East Asia, daikon is harvested and consumed throughout the region, as well as in South Asia, and is available internationally. In some locations, daikon is planted for its ability to break up compacted soils and recover nutrients and is not harvested.
The vegetable's Chinese language names are still uncommon in English. In most forms of Chinese cuisine, it is usually known as bái luóbo (white radish). Although in Cantonese and Malaysian cuisine, it is encountered as lobak or lo pak, which are Cantonese pronunciations of the general Chinese term for "radish" or "carrot" (蘿蔔). In the cuisines of Hokkien language and Teochew language-speaking areas such as Singapore, Thailand, and Taiwan, it is also known as chai tow or chai tau (菜頭). Any of these may be referred to as "radish," with the regional variety implied by context. In English-speaking countries, it is also sometimes marketed as icicle radish.
In mainland China and Singapore, the calque white carrot or misnomer carrot is sometimes used, owing to the similarity of the vegetables' names in Mandarin and Hokkien. This variant inspired the title for a popular guidebook on Singaporean street food, There's No Carrot in Carrot Cake, which refers to chai tow kway, a kind of cake made from daikon.
In North America, it is primarily grown not for food but as a Crop rotation, with the roots left unharvested to prevent soil compaction; the leaves (if harvested) are used as animal fodder. The official general name used by the United States Department of Agriculture is oilseed radish, but this is only used in non-culinary contexts. Other English terms employed when daikon is used as animal feed or as a soil ripper are "forage radish", "fodder radish", and "tillage radish".Natural Resources Conservation Service. Plants Database.

In Hong Kong, the misnomer turnip is also used. This name lends its name to the dish "turnip cake".
The Heirloom plant watermelon radish is another Chinese variety of daikon with a dull green exterior but a bright rose or fuchsia-colored center. Its Chinese name xīnlǐměi luóbó) is sometimes irregularly romanized as the shinrimei radish and sometimes translated as the "beauty heart," "beautiful heart inside," or "roseheart" radish.
The roots can be stored for weeks without the leaves if lifted and kept in a cool, dry place. If left in the ground, the texture tends to become woody, but the storage life of whole untreated roots is not long.
Certain varieties of daikon can be grown as a winter cover crop and green manure. These varieties are often named "tillage radish" because the plant grows a huge, penetrating root that effectively performs deep cultivation. The roots bring nutrients lower in the soil profile up into the higher reaches and are good nutrient scavengers, so they are good partners with instead of grasses; if harsh winters occur, the root will decompose while in the soil, releasing early nitrogen stores in the spring.
Nutrient retention is another important feature of tillage radish. The large taproot is used to retain macro- and micro-nutrients that would otherwise have the potential to be lost to leaching during the time when the field would otherwise be left empty. The nutrients from the root become readily available for the following year's crop upon the decay of the radish, which can boost yields and reduce fertilizer costs.
Daikons are also used as a forage worldwide. As a forage, they also have the side benefit of weed control. Although used elsewhere for much longer, daikon as a forage is a recent introduction in Massachusetts field practice.
Varieties
Several nonwhite varieties occur. The Cantonese lobak, lo pak, etc., sometimes refer to the usual Chinese form but is also applied to a form of daikon with a light green coloration of the top area of the root around the leaves. The Korean radish, also called mu, has a similar pale green shade halfway down from the top and are generally shorter, stouter, and sturdier, with denser flesh and softer leaves. Both are often spicier than the long white radishes.
Cultivation
The Chinese and Indian varieties tolerate higher temperatures than the Japanese ones. These varieties also grow well at lower elevations in East Africa. If moisture is abundant, it can grow quickly; otherwise, the flesh becomes overly tough and pungent. The variety Long White Icicle is available as seed in Britain and will grow very successfully in Southern England, producing roots resembling a parsnip by midsummer in good garden soil in an average year.
Culinary uses
Japan
In Japan, many types of pickles are made with daikon roots, including takuan and bettarazuke. Daikon roots can be served raw, in salads, or as sashimi's , which is prepared by meticulous .Example photograph of the technique: is frequently used as a garnish, often mixed into various dippings such as ponzu, a soy sauce and citrus juice condiment.

China
In Chinese cuisine, turnip cake and chai tow kway are made with daikon. The variety called mooli has a high water content, and some cookbooks recommend salting (or sweetening, depending on the region and context) and draining it before it is cooked. Sometimes, mooli is used as a medium for elaborately carved garnishes. More commonly, daikon is referred as bailuobo (白蘿蔔) in Mandarin or lobak in Cantonese. Bailuobo is used in various dishes for its unique and mild flavour after being boiled and cooked. For soups, bailuobo can be seen in daikon and pork rib soup (白蘿蔔排骨湯), daikon and tomato soup (白蘿蔔番茄湯), daikon and tofu soup (白蘿蔔豆腐湯), etc. Delicacies such as "shredded daikon" (白蘿蔔絲) and "cut daikon" (白蘿蔔塊) are popular domestic dishes too. Similar to Japanese cuisine, there are many types of pickles (in Mandarin Chinese: 咸菜 xiáncài / 榨菜 zhàcài) made with daikon, for example, "sour-sweet cut daikon" (酸甜白蘿蔔塊), "spicy daikon" (麻辣白蘿蔔), daikon zhacai (白蘿蔔榨菜), etc.
India
In North India, daikon is a popular ingredient used to make Indian cuisine, stuffed , , salads, pickles, and as garnish. The plant's leaves are used to make dal and kadhi, among other dishes. In South India, daikon is the principal ingredient in a variety of sambar, in which roundels of the radish are boiled with onions, tamarind pulp, lentils, and a special spice powder. When cooked, it can release a very strong odor. This soup, called mullangi sambar (, ; literally, "radish sambar") is very popular and is often mixed with rice.
Vietnam
In Vietnamese cuisine, sweet and sour pickled daikon and carrots (củ cải cà rốt chua or đồ chua) are a common condiment in bánh mì sandwiches.

Nutrition
Raw daikon is 95% water, 4% , and less than 1% each of protein and fat (table). In a reference amount of , raw daikon supplies 18 and is a rich source (20% or more of the Daily Value, DV) of vitamin C (24% DV), with no other in significant content (table).
Agricultural use
Tillage radish leaves behind a cavity in the soil when the large taproot decays, making it easier for the following year's crops, such as potatoes, to bore deeper into the soil. Potatoes grown in a rotation with tillage radish do not experience growth restrictions associated with having a shallow hardpan soil, as the tillage radish can break the hardpan, making the transfer of water and other important nutrients much easier for the root system.
Other use
Daikon is used in preparing metal surfaces for chemical patination, for example, under the Rokushō process.
