Abstract
After the method adopted to our previous papers, We have analyzed the growth of rice plant-height at Taisho (July 22rd every year) measured at the twenty agricultural experiment stations of Japan covering the period of 30 years from 1911 to 1940 and obtained factor load diagrams as shown in figures and tables in the text.
We could not clavity what factor loads were, but they were the fundamental data of our further researchs.
