We examined the difference in the growth process of soybean plants sown between rows of wheat plants and sown in the naked land. 1) Soybean plants growing between rows of wheat are more or less hygrophytic type, but after the harvest of wheat the growth becomes temporary slow and afterwards they grow well. In the late stage, the plants are in the better condition than the ones sowned in the naked land. 2) The most important stage in the growth of soybean plants sown between rows of wheat is before and after the harvest of wheat. Especially carbohydrate content of the plants was markedly increased. 3) The increase of carbohydrate content in this stage is due to the higher ability of the carbon assimilation and to the less consumption of carbohydrate in the nitrogen metabolism and dry matter production. 4) Growth and yield of soybean plants sown between rows of wheat is possibly influenced to greater extent by condition, especially intensity of radiation at the time of before and after the harvest of wheat.
