Effects of Planting Density on Yields of Aralia elata Seem

With the increase in the level of national income, the interest and demand of the wild edible plants have been increased. Aralia elata Seem is highlighted as a new income source for farmers in Korea. This study was conducted to determine the optimum planting density enhancing the commercial yield and quality in Aralia elata Seem. Yield of new shoots per 10a was increased in the dense planting of 1m×30cm by three years of planting, but it was decreased after four years of planting, which was mainly caused by the factors such as high mortality rate. The income per 10a in the planting density of 1m×50cm(2,000 plants/10a) was higher by 27% than that in the planting density of 1m×30cm(3,300 plants/10a) which was 968,00won per 10a
