For the purpose of clarifing the factors which affect the growth of Bupleurum falcatum L., the appearance of Bupleurum roots cultivated under 5 kinds of soils with or without ventilation and watering in the soil was compared. Main and hair roots grew up well in sandy loam soil, whereas main and lateral roots grew up in clay loam soil. The content of saikosaponins in the root was shown to be highest in stream or mountain sand. The number of blooming increased and time to flowering came earlier with soil ventilation. Gaseous phase in the three phase distribution of soil increased with ventilation or watering. The yield of Bupleurum root also increased with soil ventilation or watering in all kinds of soils. As a result, it is concluded that the soil ventilation is a useful method for the cultivation of B. falcatum owing to the change in the physical properties of soils.
