On the effect of the storage method of seed potato on the propagation value

Abstract

1. The author have studied concerning the effect upon the propagation value of the propagating agents of the pit storage, cold storage and indoor storage methods. 2. As to the sprouting, it was recognized that the method of the pit storage was the best, the cold storage the second and indoor storage the third. 3. In the early period of growth after planting the stem length of the plant from the pit storage was less than that of the plant from the cold storage, but in the later period the result was inverse, that is to day that the growth of the plant from the indoor storage was usually the least of all. 4. According to the result from variance analysis about the yield, there was a significant difference between the production values by these methods of storage. As to the total weight of the potatoes, the yield of plants from outdoor pit storage was the best, cold storage the next and indoor storage the least. There were comparatively many large and medium sized tubers from plants stored in outdoor, but plants from cold storage produced many small and undersized tubers. 5. From the result of this experiment it was recognized that pit storage was the best method for propagating agents in the case of small scale.
