This experiments were conducted to clear the influence of various amounts of phosphorous and potash supply on growth and fruiting of buckwheat plant. The Shinano No. 1 was used as materials. The results are summmarized as follows ; 1) By increasing the amount of phosphorbus supply, the plant grows higher, while the diameter of stem (at 5 cm level from the ground) is not so large. By increasing the amount of potash, it was found that the reverse was true. Little differences were observed in germination percentage between potash and phosphorous plots, but as to the flowering, the latter is earlier than the former. The flowering period is postponed by the phosphorous supply. The stem becomes hard gradually by increasing the amount of both fertilizers, particularily by potash. 2) The number of flowers are much earqer in phosphorous plots than in potash plots. The fruiting percentage is not affected by the phosphorous, but affected remarkably by potash. The blasting percentage comes up about to 5 per dent in potash plot's, and about 15 per cent in phosphorous plots. It may be said that potash is one of the most remarkable factors for buckwheat plant ; on fruiting and hardening.
