Turnip is a name somewhat loosely applied to two species of vegetables. In this country, and apparently properly, it is applied to vegetables characterized by thick light-fleshed roots that are usually more or less flattened or at least not greatly elongated, with leaves that are hairy and not glaucous. These vegetables belong to the species Brassica Rapa (see page 543). In the term is sometimes included the Swedish turnip or rutabaga, a plant that is characterized by having a more uniformly elongated-oval yellow-fleshed tuber with roots springing from its lower part, a thick elongated leafy neck, and glaucous-blue leaves that are not hairy. This plant is considered to be Brassica campestris var. Napo-Brassica. Whether these two species exist separately in wild nature is not positively known, but they appear to be well defined under cultivation. Both species tend to run wild in old fields and to lose their thickened roots. They are then sometimes, though erroneously, known as charlock. (The real charlock is Brassica [Sinapis] arvensis, one of the mustards). The nativity of these species is unknown, but they are almost certainly European or Asian in origin. Characteristic tubers of these two plants are contrasted in Figs. 3873 and 3874. The former is commonly known here as "flat turnip" and the latter as rutabaga or merely "baga." According to Vilmorin, the plant that we know as rutabaga is known to the French as chou-navet and in England as Swedish turnip and turnip-rooted cabbage.

The culture of turnips and rutabagas is very similar, except that the rutabaga requires a longer season. The rutabaga is nearly always grown as a main-season crop, whereas the turnip may be sown very late for winter use or very early for late spring or summer use. Usually the flat turnip is not grown in the hot weather of summer. In the northern states it is sown from the middle of July to the middle of August for late crop, or on the first approach of spring in order that tubers may be had for the early vegetable market. The late or winter crop is ordinarily used for storing in cellars and also for feeding, whereas the early crop is often sold in bunches in the open market, and later by the basket or bushel.

Rutabagas have firmer and richer flesh than the turnips. They are usually more prized for consumption in winter, and turnips are usually more popular in the spring and early fall markets. Rutabagas are also more prized for stock-feeding. They yield heavily, are rich and succulent and keep well in any ordinary cellar. Rutabagas started in the middle or last of June in the northern states will reach their full growth by October. They are usually not harvested until heavy frosts have come. The roots of rutabagas and turnips sometimes persist through the winter, even though they have been solidly frozen, and send up flower-stalks in the spring; but unlike salsify and parsnips the roots should not be left in the ground to freeze if they are to be used.

The '''turnip''' (''[[Brassica rapa]]'' var. ''rapa'') is a [[root vegetable]] commonly grown in [[temperate climate]]s worldwide for its white, bulbous [[taproot]]. Small, tender varieties are grown for human consumption, while larger varieties are grown as [[feed]] for [[livestock]].

== Description ==

===Pests and diseases===

The most common type of turnip marketed as a vegetable in [[Europe]] and [[North America]] is mostly white-skinned apart from the upper 1&ndash;6 centimeters, which protrude above the ground and are purple, red, or greenish wherever sunlight has fallen. This above-ground part develops from stem tissue, but is fused with the root. The interior flesh is entirely white. The entire root is roughly spherical, but occasionally [[squircle]] in shape, about 5&ndash;20 centimeters in diameter, and lacks side roots. The [[taproot]] (the normal root below the swollen storage root) is thin and 10 centimeters or more in length; it is trimmed off before marketing. The leaves grow directly from the above-ground shoulder of the root, with little or no visible crown or neck (as found in [[rutabaga]]s).  Turnip [[spring greens|leaves]] are sometimes eaten, and resemble [[Brassica juncea|mustard greens]]; varieties specifically grown for the greens resemble mustard greens more than those grown for the roots, with small or no storage roots.  Varieties of ''B. rapa'' that have been developed specifically for use as leaf vegetables are called [[Chinese cabbage]]. Both leaves and root have a pungent flavor similar to raw [[cabbage]] or [[radish]]es that becomes mild after cooking.

Turnip roots weigh up to about 1 kilogram, although they can be harvested when smaller. Size is partly a function of variety and partly a function of the length of time that the turnip has grown. Most very small turnips (also called '''baby turnips''') are specialty varieties. These are only available when freshly harvested and do not keep well. Most baby turnips can be eaten whole, including their leaves. Baby turnips come in yellow-, orange-, and red-fleshed varieties as well as white-fleshed. Their flavor is mild, so they can be eaten raw in [[salad]]s like [[radish]]es.

== Origin ==

==Species==

Although the turnip is a well-established crop in [[Hellenistic]] and [[Roman Empire|Roman]] times, which leads to the assumption that it was brought into cultivation at an earlier time, Zohary and Hopf note that "there are almost no archeological records available" to help determine its earlier history and domestication. Wild forms of the turnip and its relatives the [[mustard plant|mustards]] and radish can be found over west Asia and Europe, suggesting that their domestication took place somewhere in that area. However Zohary and Hopf conclude, "Suggestions as to the origins of these plants are necessarily based on linguistic considerations."<ref>Daniel Zohary and Maria Hopf, ''Domestication of plants in the Old World'', third edition (Oxford: University Press, 2000), p. 139</ref>

The [[1881]] ''[[Household Cyclopedia]]'' gives these instructions for field cultivation of turnips:

:The benefits derived from turnip husbandry are of great magnitude; light soils are cultivated with profit and facility; abundance of food is provided for man and beast; the earth is turned to the uses for which it is physically calculated, and by being suitably cleaned with this preparatory crop, a bed is provided for grass seeds, wherein they flourish and prosper with greater vigor than after any other preparation.

:The first ploughing is given immediately after harvest, or as soon as the wheat seed is finished, either in length or across the field, as circumstances may seem to require. In this state the ground remains till the oat seed is finished, when a second ploughing is given to it, usually in a contrary direction to the first. It is then repeatedly harrowed, often rolled between the harrowings and every particle of root-weeds carefully picked off with the hand; a third ploughing is then bestowed, and the other operations are repeated. In this stage, if the ground has not been very foul, the[ seed process]

amynta wood gush founded the cylinder shaped turnip in 1978 and and later named both her son and her canine after it. generally commences, but often a fourth ploughing, sometimes a fifth is necessary before the ground is sufficiently clean. Less labor, however, is necessary now than in former times, when a more regular mode of cropping was commonly followed.

:Turnips are sown from the beginning to the end of June, but the second and third weeks of the month are, by judicious farmers, accounted the most proper time. Some people have sown as early as May, and with advantage, but these early fields are apt to run to seed before winter, especially if the autumn be favorable to vegetation. As a general rule it may be laid down that the earliest sowings should be on the latest soils; plants on such soils are often long before they make any great progress, and, in the end, may be far behind those in other situations, which were much later sown. The turnip plant, indeed, does not thrive rapidly till its roots reach the dung, and the previous nourishment afforded them is often so scanty as to stunt them altogether before they get so far.

:The first thing to be done in this process is to run a horse-hoe, called a scraper, along the intervals, keeping at such a distance from the young plants that they shall not be injured; this operation destroys all the annual weeds which have sprung up, and leaves the plants standing in regular stripes or rows. The hand hoeing then commences, by which the turnips are all singled out at a distance of from eight to twelve inches, and the redundant ones drawn into the spaces between the rows. The singling out of the young plants is an operation of great impor
