Abstract
Hairy vetch(Vicia villosa Roth) which is legume fur winter cover crop can supply nitrogen for companion crop and soil. The purpose of this study was to improve the forage quality and productivity using forage crop and hairy vetch in winter season fer three years. The results of this experiments were summarized as follows. Plant height of rye was decreased but hairy vetch was increased. The heading stage of rye did not show difference among the treatments. The content of dry mater(DM) was decreased with increased ratio of hairy vetch/rye but it did not show significant difference between seeding methods. Crude protein(CP) content tended to increase in mixture plots. Acid detergent fiber(ADF) and NDF(neutral detergent fiber) content of mixture plots were lower than that of rye mono-cultivated. In vitro dry matter digestibility(IVDMD) and TDN(total digestible nutrient) content were showed inverted tendency. The highest DM yield was in rye mono-cultivated, but it was similar between mono-cultivated and mixture I (P<0.05). In the CP yield, it did not show the significant difference between rye mono-culture and mixture I . The content of total nitrogen in soil showed slight increase as 0.06∼0.08%. Conclusively, mixture I showed equal or superior productivity and quality comparing with rye mono-cultivated, mixture I would be recommended to produce higher yield and to conserve soil environment.
