VETCH , in See also:botany, the See also:English name for Vicia saliva, also known as tare, a leguminous See also:annual See also:herb with trailing or climbing stems, See also:compound leaves with five or six pairs of leaflets, reddish-See also:purple See also:flowers See also:borne singly or in pairs in the See also:leaf-See also:axis, and a silky pod containing four to ten smooth seeds . The See also:wild See also:form, sometimes regarded as a distinct See also:species, V. angusti-(olia, is See also:common in dry soils . There are two races of the cultivated vetch, See also:winter and See also:spring vetches: the former, a See also:hardy form, capable of enduring See also:frost, has smoother, more cylindrical pods with smaller seeds than the summer variety, and gives less bulk of See also:stem and leaves . The spring vetch is a more delicate plant and grows more rapidly and luxuriantly than the winter variety . The name vetch is applied to other species of the genus Vicia . Vicia orobus, See also:bitter vetch, and V. sylvatica, See also:wood vetch, are See also:British See also:plants . Another British plant, Hippocrepis, is known as horseshoe vetch from the fact of its pod breaking into several horseshoe-shaped See also:joints . Anthyllis vulneraria is See also:kidney-vetch, a herb with heads of usually yellow flowers, found on dry See also:banks . Astragalus is another genus of See also:Leguminosae, and is known as See also:milk-vetch . Vetches are a very valuable See also:forage See also:crop . Being indigenous to See also:Britain, and not fastidious in regard to See also:soil, they can be cultivated successfully under a See also:great diversity of circumstances, and are well adapted for poor soils . By combining the winter and spring varieties, and making several sowings of each in its See also:season at intervals of two or three See also:weeks, it is practicable to have them See also:fit for use from May till See also:October, and thus to carry out a See also:system of soiling by means of vetches alone . But it is usually more expedient to use them in See also:combination with grass and See also:clover, beginning with the first cutting of the latter in May, taking the winter vetches in See also:June, recurring to the See also:Italian ryegrass or clover as the second cutting is ready, and afterwards bringing the spring vetches into use . Each crop can thus be used when in its best See also:state for See also:cattle See also:food, and so as gratefully to vary their See also:dietary . |
