Experience of introduction of perennial wild species of vetch (VICIA L.) in the conditions of the Middle Urals

摘要

Research on the introduction of perennial wild species of vetch was carried out for 5 years (2007-2011) in "Uralets" work-study unit located in the Beloyarsky district of the Sverdlovsk Region on the educational-experimental plot of the Faculty of Agricultural Technologies and Land Management. Experimental scheme included 3 variants: Vicia sepium L. (bush vetch) - control; Vicia sylvatica L. (wood vetch); Vicia megalotropis Ldb. (Siberian vetch). Once-cut stand, cutting was carried out in the phase of heavy flowering of the studied plants. It was found that during years of research wood vetch was developing most intensively. It is characterized with the highest average daily growth which ranged from 2.6 to 3.5 cm. Siberian vetch showed lower values, its average daily growth during all years of research did not exceed 1.1-1.5 cm. Average productivity of studied species during all years of observations (2008-2011) was as follows: Vicia sepium L. - 13.6 t/ha; Vicia sylvatica L. - 17.9 t/ha; Vicia megalotropis Ldb. - 11.7 t/ha.
