Background : This experiment was conducted to select suitable industrial crop after Panax ginseng cultivation under the greenhouse in the middle area. Methods and Results : This experiment was conducted in greenhouse of Chungbuk Agricultural Research Service and extension services from 2015 and 2016 years. Ginseng grown four years in greenhouse. After cropping of Panax ginseng was transplanted Cynanchum wilfordii, Platycodon grandiflorm, Dioscorea opposita, and Codonopsis lanceolata. Non-cultivated field that were grown sesame. Cynanchum wilfordii, Platycodon grandiflorm, and Codonopsis lanceolata was collected in the Chungbuk area and Dioscorea opposita was collected in Andong-si. Each industrial crop after panax ginseng cultivation under the greenhouse was sowing from late April to early May 2015 years. The growth and yield of crop examined in the experiment were good on the whole except Codonopsis lanceolata without disease due to continuous cropping of Panax ginseng. The yield of Cynanchum wilfordii, Platycodon grandiflorm, Dioscorea opposita, and Codonopsis lanceolata was 803kg, 1,393kg, 1031kg, 412kg per 10a respectively, and the every decline yield index was by 1%, 8%, 12%, and 31% respectively. The proper crop in after cropping of Panax ginseng was cynanchum wilfordii, which was yielded 1,393kg per 10a by fresh tuber and it was 1% decline compared to the non-cultivated field. Conclusion : In this study, Cynanchum wilfordii, Platycodon grandiflorm, Dioscorea opposita was recommended as a crop after Panax ginseng cultivation under the greenhouse in the middle area.
