On the relation between the moisture content and the storable term of rough rice, the materials which were cultured by different methods or harvested by different machines were studied. According to the deterioration developed on the rice surface in newly threshed fresh rough rice in storage, deteriorated rice grains were classified into three groups, the spotted rice, the opaque rice and the rotten rice. The storable term was shown by the time during which the total of deteriorated grain was less than 5%. 1. The suitability for storage of rough rice obtained from cultivation in the same condition of soil and climate was not affected by variety, the time of maturity or the stage to maturity, lodging, harvest machine or cropping district. (Fig 1, 2, 5, 6, 8) 2. The relation between the moisture content of rough rice and its storable term for ordinaly rice harvested in a fine year was as follows. The rice of moisture content 18% could be stored for 30 days without changes, the rice of 19% kept 20 days, of 20% kept 15 days, of 21% kept 7-10 days, of 22% kept 7days, of 23% kept 1-3 days. (11 of capacity, at 10-25℃ of room temperature. Fig. 2) 3. The climatical environment from flowering time to mature stage considerably affected the suitability for storage of paddy, and the paddy from the fine climate districts or the fine years were better than in the rainy district ot in the rainy years.(Fig. 3, 7) 4. The late harvested rough rice in high moisture conditions was of worse suitability for storage than ordinary harvested, because in some of the stored rice, it had changed to the opaque. (Fig. 4)
