Abstract In order to improve soil quality of mountainous highland in Gangwon province, green manure cultivation is necessary rather than continuous cultivation of the same crops. One of the difficulties to grow green manure in the region is increase in soil hardness in spring after wintering of rye, the current major green manure. The objectives
of the study were to select proper green manure plants suitable to environment of mountainous highland and to compare the application effect of the green manure with rye. Hairy vetch, wheat, and rye showed relatively high survival rate (greater than 35%) and plant height (greater than 45 cm) after winter compared with the other seven
green manures. Rye and wheat increased soil penetration resistance to 2.7 and 3.0 MPa, respectively. Although yields of hairy vetch and wheat were less than that of rye, greater contents of nitrogen and calcium for the two green manures than the contents of rye indicated comparable nutrient supply to the following crops. The application effects of hairy vetch and wheat on soil chemical characteristics and Chinese cabbage yield were not significantly different from those of rye. The results obtained in the study implied that hairy vetch and wheat could substitute rye as a green manure for mountainous highland in Gangwon province.
