Co-incorporation of Leguminosae with Gramineae could reduce the risk of nitrogen starvation phenomena caused by appling green manure of Gramineae alone. The objective of the study was to examine the effect of mixed sowing of hairy vetch and rye seeds on soil quality in mountainous highland. Mixed sowing of hairy vetch and rye increased the yield of green manure and nutrients compared with those for sowing of hairy vetch or rye alone. The yield of green manure from row seeding was $5.3Mg\;ha^{-1}$ compared with $4.8Mg\;ha^{-1}$ for broadcast seeding. Incorporation of the two green manure crops increased yield of red-bean by 58~92% as compared with yield for incorporation of rye alone. The results obtained in the study imply that mixed sowing of hairy vetch and rye can solve the problem of low emergence of hairy vetch in spring and high C/N ratio and rough incorporation of rye, in addition to increase in yield of green manure.
