In order to examine the differences on dietary fibers : soluble (SDF), insoluble (IDF), and total (TDF), protein, and oil contents, and weight of 100 seeds on soybeans, 7 soybean cultivars were cultivated in upland, drained paddy field and late-seeding time at Tohoku National Agricultural Experiment Station in 1995. The drained paddy field culture, as compared with the upland culture, gave no different of SDF, IDF, TDF contents, high protein and low oil contents and heavy weight of 100 seeds. Significant differences were observed in protein and oil contents and weight of 100 seeds. From the contribution ratio of the field condition and cultivar, cultivar was higher than field condition in dietary fibers, protein, oil contents and weight of 100 seeds. The late-seeding time culture, as compared with normal-seeding time culture, gave slightly high IDF content, low oil content, and light weight of 100 seeds. As to the variation of IDF content, it was presumed that increased IDF content was influenced by reduced weight of 100 seeds. The low oil content was influenced by low temperature during ripening. Significant differences were observed in IDF, oil contents and weight of 100 seeds. From the contribution ratio of the seeding time and cultivar, cultivar was higher than seeding time in dietary fibers, protein and oil contents and weight of 100 seeds. However, slightly high contribution ratio was also observed in oil content in seeding time.
