Abstract
1) System of foliar emergence in soybean plants, Ou-No. 13, was observed during 1955-57 in relation to the plant density, the manuring and the sowing time. 2) Foliar emergence of main stem had one or two turning points and was linear before and after this point and interval of each foliar emergence after this point was shorter than before. Interval of foliar development was markedly affected by the sowing time and it was fastened at the late planting than earlier. 3) Branches developed normally from downward node to upper node and the interval of foliar emergence of each branches was 3 or 4 days. Same as the main stem, the sowing time effected most upon this interval and it was fastened in the late sowing plot. 4) Simultaneous foliar emergence between main stem and branches was observed at the distance of 4 and 5 sections and these numbers of sections were varied a little according to the growth stage.
