We have investigated on the growth and yield of soybean plants which were treated with excessive supply of soil moisture during 5 days at different growing period and obtained the following results. (1) In every series, yield of plants were decreased more or less by treatment, but the degree of decrease varied with the different stages when they were treated. (2) In the 1st series where plants were treated during 5 days-period when they were young, vegetative growth was prevented, having low stems, few branches, therefore this series showed poorest yield except that of the 2nd series. (3) In the 2nd series where plants were treated during 5 days-period after the date of flower bud differentiation, vegetative growth was prevented, having especially few branches, lightest stems; and resulting in the poorest of all. (4) In the 3rd series where plants were treated during 5days-period after the date of flowering plants, showed better yield than the 1st and the 2nd series, because their vegetative growth was not so disturbed and seems as normal. But their yield were poor as compared with control plants.
