The study was carried out to elucidate the influenced of shading and mulching with polyethylen vinyl on growth and yield of Cinidium officinale Makino, and improve the cultivation method of those medicinal plants in northern area of Gyeong-buk province, Korea. Top fresh weight of Cinidium officinale Makino was increased by both 35 % and 55% shading compared to the non-shadingand decreased by 75 % shading, but that of Ligusticum chuanxing Hart. Was decreased by the shading tested The summer wilt of Cinidium officinale Makino severely occurred in non-shading but greatly reduced by 55 % or 75 %shading, while no difference was observed in Ligusticum chuanxing Hort, between the shading and the non-shading. Dry root yield Cinidium officinale Makino was increased by 17 % and 19 % in 35 % and 55 % shading levels, respectively, compared to the dry root yield(254kg/10a) in non-shading. However, it was decreased in Ligusticum chuaxing Hort. by the shading. Emergence ratio of Cinidium officinale Makino was increased by black polyethylen vinyl mulch but decreased by transparent polyethylen vinyl mulch, compard to non-mulch. Polyethylen vinyl mulch increased the top fresh weight of Cinidium officinale Makino Especialy black polythylen vinyl mulch was very effective on increasing the top fresh weight. Dry root yield of Cinidium officinale Makino was increased by 32 % and 30 %, respectively, compared to the non-shading.
