Agriculture -- Canada; Agriculture -- United States; Farm produce -- Canada; Farm produce -- United States. ROOT CROPS ROOT CROPS 547 The parsnip is grown usually on strong loams and even on clay soils. The details of culture are simi- lar to those given for carrots [which see]. It is important, however, that the seed shall not be more than one year old and that it be sown near the surface. Four to six pounds are re- quired to seed an acre. Since the roots are not injured by frost when left in the ground over winter, harvesting may be deferred until spring, if desired. At the present time there are a few well-recognized varieties which are em- braced in two main types : (1) the long type, which includes the Hollow Crown | or Student variety and its ^^^^ ^ ^ strains ; (2) the short or round t\T)e, which is of comparatively recent in- troduction. Both of these types are found wild. Sugar-beet. Beta vulgaris, Linn. Chenopodiacece. A mangel developed for the production of sugar, and a product of the past century. So far as cul- ture and use as stock-food is concerned, it is similar to mangel. [See separate article on Sugar-beet] even in individuals of the same variety, being modified by variations in the plants themselves, the soil and the method of cultivation. As usually grown, they are regarded as biennial plants. In this discussion it is proposed to treat all three types under the one heading because, although botanically somewhat different, their uses and the methods of culture are Turnip. 5rassicc, sp. Cruciferce. Figs. 778,784,785. Turnips are grown for their thickened roots, which are formed during the first year of growth and are used as food for stock. The name "turnip" is here used in its widest sense and embraces the common turnip {Bras.^ica Rapa, var. depressa, DC), the rutabaga, a Swedish turnip {Brassica Campestris,. Please n
