Ruta-Baga, or Swede Turnip

Russian Turnip. French Turnip. Brassica campestris Ruta-baga. De Cand.

The Ruta-baga, or Swede Turnip, is supposed by De Candolle to be analogous to the Kohl Rabi; the root being developed into a large, fleshy bulb, instead of the stem. In its natural state, the root is small and slender; and the stem smooth and branching,—not much exceeding two feet in height.

The bulbs, or roots, are fully developed during the first year. The plant flowers, and produces its seeds, the second year, and then perishes. Although considered hardy,—not being affected by even severe frosts,—none of the varieties will withstand the winters of the Northern or Middle States in the open ground. The crop should therefore be harvested in October or November, and stored for the winter, out of danger from freezing. Most of the sorts now cultivated retain their freshness and solidity till spring, and some even into the summer; requiring no particular care in their preservation, other than that usually given to the carrot or the potato.

Soil and Cultivation.—All the varieties succeed best in a deep, well-enriched, mellow soil; which, previous to planting, should be very deeply ploughed, and thoroughly pulverized by harrowing or otherwise. Some practise ridging, and others sow in simple drills. The ridges are usually formed by turning two furrows against each other; and, being thus made, are about two feet apart. If sown in simple drills, the surface should be raked smooth, and the drills made from sixteen to eighteen inches apart; the distance to be regulated by the strength of the soil.

Seed and Sowing.—About one pound of seed is usually allowed to an acre. Where the rows are comparatively close, rather more than this quantity will be required; while three-fourths of a pound will be amply sufficient, if sown on ridges, or where the drills are eighteen inches apart. The sowing may be made from the middle of May to the 25th of July; the latter time being considered sufficiently early for growing for the table, and by some even for stock. Early sowings will unquestionably give the greatest product; while the later-grown bulbs, though of smaller dimensions, will prove of quite as good quality for the table.

To raise Seeds.—Select the smoothest and most symmetrical bulbs, and transplant them in April, two feet asunder, sinking the crowns to a level with the surface of the ground.

The seeds are very similar to those of the common garden and field turnip, and will keep from five to eight years.

Varieties.—The varieties are as follow:—

Ashcroft.

Bulb of medium size, ovoid, very smooth and symmetrical; neck very short, or wanting. Above ground, the skin is purple; below the surface, yellow. Flesh yellow, very solid, fine-grained, and of excellent flavor. It forms its bulb quickly and regularly; keeps in fresh and sound condition until May or June; and well deserves cultivation, either for agricultural purposes or for the table.

Common Purple-Top Yellow.

An old and long-cultivated sort, from which, in connection with the Green-top, have originated most of the more recent and improved yellow-fleshed varieties. Form regularly egg-shaped, smooth, but usually sending out a few small, straggling roots at its base, near the tap-root; neck short; size rather large,—usually measuring six or seven inches in depth, and four or five inches in its largest diameter; skin purple above ground,—below the surface, yellow; flesh yellow, of close, firm texture, and of good quality. It is very hardy; forms its bulb promptly and uniformly; and in rich, deep soils, yields abundantly. For thin and light soils, some of the other varieties should be selected.

Early Stubble.

Bulb round, smooth, and regular. The skin, where exposed to light and air, is of a brownish-green; but, where covered by the soil, yellow. The flesh is firm, and well flavored.

The Early Stubble is recommended as forming its bulbs quickly and uniformly, and as being well adapted for late sowing. It yields abundantly; keeps well; is a good sort for the table; and, in some localities, is preferred to the Common Yellow for cultivation for farm purposes.

Green-Top Yellow.

In form and foliage, this variety resembles the Common Purple-top; but usually attains a larger size when grown in similar situations. Skin, above the surface of the soil, green; below ground, yellow. The flesh is solid, sweet, and well flavored, but inferior to that of the Purple-top. It keeps well, is of fair quality for the table, and, on account of its great productiveness, one of the best of all varieties for growing for feeding stock.

Green-Top White.

Bulb turbinate, smooth, and symmetrical. The skin above ground is of a fine, clear, pea-green; often browned or mellowed where exposed to the direct influence of the sun: below the surface of the ground, it is uniformly white. The flesh is also white, comparatively solid, very sweet, and of fair quality for table use. It differs from the Purple-top White, not only in color, but in size and quality; the bulbs being larger, and the flesh not quite so firm or well flavored.

The Green-top White is productive; continues its growth till the season has far advanced; is little affected by severe weather; and, when sown in good soil, will yield an agricultural crop of twenty-five or thirty tons to an acre.

Laing's Improved Purple-Top. Law. and Gen. Farmer.

This variety differs from most, if not all, of the varieties of Swedish turnips, in having entire cabbage-like leaves, which, by their horizontal growth, often nearly cover the surface of the ground. In form, hardiness, and quality, it is fully equal to any of the other sorts. Growing late in the autumn, it is not well adapted to a climate where the winter commences early. It has little or no tendency to run to seed in the fall; and even in the spring, when set out for seed, it is a fortnight later in commencing this function than other varieties of Ruta-bagas. It requires good land, in high condition; and, under such circumstances, will yield abundantly, and is worthy of cultivation. The bulb, when well grown, has an almost spherical form; a fine, smooth skin, purple above ground, yellow below, with yellow, solid, and well-flavored flesh.

Purple-Top White.

Bulb oblong, tapering toward the lower extremity, five or six inches in diameter, seven or eight inches in depth, and less smooth and regular than many of the yellow-fleshed varieties. The skin is of a clear rich purple, where it comes to air and light, but, below the ground, pure white; flesh white, very solid and fine-grained, sugary, and well flavored.

The variety is hardy, productive, keeps remarkably well, is good for table use, and may be profitably grown for agricultural purposes. Upwards of twenty-eight tons, or nine hundred and sixty bushels, have been raised from an acre.

River's.

Root regularly turbinate, or fusiform, of full medium size, smooth, and with few small or fibrous roots; neck two inches long; skin, above ground, green, washed with purplish-red where most exposed to the sun,—below ground, yellow; flesh yellow, firm, sweet, and well flavored. Esteemed one of the best, either for stock or the table. Keeps fresh till May or June.

Skirving's Purple-Top.

Skirving's Improved Purple-top. Skirving's Liverpool. Southold Turnip, of some localities.

Bulb ovoid, or regularly turbinate, and rather deeper in proportion to its diameter than the common Purple-top Yellow; surface remarkably smooth and even, with few fibrous roots, and seldom deformed by larger accidental roots, although, in unfavorable soils or seasons, a few coarse roots are put forth in the vicinity of the tap-root; size full medium,—five to seven inches in length, and four or five inches in diameter. Sometimes, when sown early in good soil, and harvested late, the average will considerably exceed these dimensions. Neck short, but, when grown in poor soil, comparatively long; skin, above ground, fine, deep purple,—below ground, yellow,—the colors often richly blending together at the surface; flesh yellow, of solid texture, sweet, and well flavored.

This variety was originated by Mr. William Skirving, of Liverpool, Eng. In this country it has been widely disseminated, and is now more generally cultivated for table use and for stock than any other of the Swede varieties. The plants seldom fail to form good-sized bulbs. It is a good keeper; is of more than average quality for the table; and long experience has proved it one of the best sorts for cultivation on land that is naturally shallow and in poor condition. On soils in a high state of cultivation, upwards of nine hundred bushels have been obtained from an acre.

In sowing, allow twenty inches between the rows, and thin to ten or twelve inches in the rows.

Sweet German.

Bulb four or five inches in diameter, six or seven inches in depth, turbinate, sometimes nearly fusiform. In good soil and favorable seasons, it is comparatively smooth and regular; but, under opposite conditions, often branched and uneven. Neck two or three inches in length; skin greenish-brown above ground, white beneath; flesh pure white, of extraordinary solidity, very sweet, mild, and well flavored.

It retains its solidity and freshness till spring, and often at midsummer has no appearance of sponginess or decay. As a table variety, it must be classed as one of the best, and is recommended for general cultivation.

White French.

Long White French.

The roots of this variety are produced entirely within the earth. They are invariably fusiform; and, if well grown, measure four or five inches in diameter, and from eight to ten inches in length. Foliage not abundant, spreading; skin white; flesh white, solid, mild, sweet, and delicate. It is not so productive as some other varieties, and is therefore not so well adapted to field culture; but for table use it is surpassed by few, if any, of its class.

A rough-leaved, fusiform-rooted variety of the common garden-turnip: is known by the name of "White French" in many localities; but, according to the most reliable authority, that name has not only long been used in connection with, but properly belongs to, the white turnip above described.
