Three different genotypes soybeans were adopted in this experiment under three fertilizer levels.The object of this study was to investigate protein accumulation regulation of soybean cultivars under the condition of different nutrient levels, and their effects on soybean yield and quality, and to provide theoretical evidence for breed, cultivation and agricultural production, also man-powered controllable locations. The concentration of N in the leaves declined after seedling stage, then increased again at stage of early flowering, and started to decrease up to leaf senescence, declined rapidly from seed-filling season to stage of yellow ripeness. The concentration of N in the stems and pod walls declined with growth stage. High seed protein genotypes exhibited higher N assimilating and partitioning during whole growth stages. Pod walls were media of N partitioning. Protein was accumulated mainly during the later period of reproductive growth stage up to harvest, so plant growth after stage of yellow ripeness could not be neglected.
