1. For the study on the cultivation of Jerusalem Archichocke, especially the fundamental study of its yield, the dispersion phases of tuber were investigated first. 2. Between the tubers and stolons, the correlation was found that the magnitude of tubers is in direct proportion to the length, depth and thickness of stolons and is in inverse proportion to the thickness of origins from which the stolons grow. 3. For instance, the means of stolons were 57.60±1.679cm in length, 13.06±0.244cm in depth, 3.21±0.045mm in thickness and the mean of origins was 4.38±0.159cm in height. 4. As for the directions of tuber development, the ratio was each 20% both in east and west, 30% in north and south. The direction of dike was north to south. 5. In spite of the negligence of Jerusalem Archichocke cultivation, it grows flourishingly, but in its harvest a great deal of labor is required. If the way of harvest be rough, it is feared that the next cultivation will be hindered by the abundant presence of those which are missed to be dug up. 6. For the investigatioa of Jerusalem Archichock yield, it is required that the way of harvest, the extent of fineness or coarseness etc. must be considered together with the yield quantity itself.
