1) The seasonal variation in santonin content and the yield of crop were examined with the second year growth of Artemisia kurramensis Qaz., sown at Kasukabe in April 1950, during July 21, 1951, to November 2, 1951 (Table I). The results showed that the yield of crop harvested on August 21 was the largest with 246.7kg per 10 ares on air dry basis, with the highest santonin content of 2.341%, which is enough to rival that of Flos Cinae (flowers of A. Cina Willk.).
2) In the same way, the seasonal variation in santonin content and the yield of crop were examined with the first year growth of the same plant, sown in March 1951, during September 20, 1951, to March 18, 1952 (Table II).
3) In general, both the santonin content and the yield of crop increase extremely in the second year growth, when sown in spring.
4) The cultivation of A. kurramensis in Japan is largely dependent on the amount and number of days of rain during summer, especially in July and August.
5) Some knowledges were obtained on the breeding of seedlings of the autumn-sown plant.
