Effect of the Application of Several Organic Materials on Ginseng Growth

수종유말물 시용이 인삼생육에 미치는 영향

To search for substituents of greens, several organic materials such as rice straw, barley straw, corn stem and manufactured compost were applied in a ginseng cultivating field. The yields of six year old ginseng harvested in the rice straw, barley strait and corn stem treated field were similar to or higher than that of the greens treated one. The varied amount of applied substituents resulted in a yield change, but statistical linearity was not found. The growth of ginseng aerial part and soil physicochemical property in the field fortified with these substituents showed similar results to those of the greens treated one. So, it is though that these organic materials can substitute for greens.
