Swertia japonica was cultivated in various soil mixtures composed principally of compost and sandstone, granite, basalt, shist or volcanic ashes. For the first year of cultivation, the growth of the plants was all alike regardless of the soil used. For the second year, however, the plants cultivated in the soil comprising shist showed marked decrease in viability. Slight decrease in viability was also observed among the plants grown in the soil of granite or volcanic ashes. The highest yield of plant was obtained when they were grown in sandstone or basalt while the lowest yield was given when shist was used. The content of bitter components (amaroswerin and amarogentin) was the lowest when the plants were grown in shist. These results show that the soil composed of sandstone or basalt as a principal ingredient, is quite satisfactory while the soil composed of shist is most undesirable for the cultivation of S. japonica.
