Abstract

|
The crop rotation of rice and ginseng in paddy field has very important meaning because up-land field suitable for ginseng cultivation is now being insufficient day by day in main ginseng production area. This studies were conducted to define basic problems related to ginseng cultivation and replanting in paddy field. In Keumsan district, the most serious problem on ginseng cultivation in paddy field was excess of mineral salts left behind in the soil of rice cultivation. The amounts of organic matters, CEC and the mineral elements including potassium were higher in the soil of paddy ginseng field compared to those of upland. Plant growth of 3 and 4 year old ginseng and root yield of four year old ginseng cultivated in paddy field of 1st and replanting were not decreased compared to those of 1st - planting of up-land field, but those were significantly decreased in replanted compared to those of first planted upland field. Crop rotation with ginseng and rice in paddy field seemed to be a good way to avoid hazards of continuous cropping of ginseng with it's outyield of root and less infection of diseases. Amounts of crude saponin and ginsenosides of ginseng cultivated in paddy field were not differ from those of upland field.
