1) It was found that the cultivation of Ammi visnaga LAM. in Japan should start with autumn sowing during the middle of October, at the latest, from the point of growth, yield of fruit, and content of khellin (Table I).2) The optimal soil moisture in the said cultivation seems to be in the range of 60-70% of the water capacity from the point of growth, yield of fruit, and khellin content (Table II).3) This plant grows favorably in the soil with pH ranging from 6.5 to 7.5, with neutral reaction as the median point.4) It was confirmed through experimental cultivation extending from 1951 to 1955 that the cultivation of this plant should be made in a place with small amount of rainfall during the summer and a well-drained soil rich in clay (Tables II and III).5) Comparative cultivation was carried out with five foreign strains with different origin (khellin content of the original seed, 0.61-0.94%) and the khellin content of the fruit from these cultivated plants was 0.32-0.51%, indicating a fair decrease of the content. However, this was thought to be due to the profuse generation of diseases during August, before flowering, and unhealthy fruit had been mixed (Table IV).6) In one individual plant, the fruits that ripened earlier seemed to have higher content of khellin (Table V).
