1. Two soybean varieties, 'Chakotsubu' and Akidaizu' (Table l), were sown separately and mixed. together, respectively, in a randomized block design vfith three replications. Additionally a set of plots was prepared for the measurement at the young stages of growth. To find the effect of competition orl assimilative activity, "half-leaf weighing method was adopted by the fcllowing procedure. Eighteen leaf-disks of I sq. cm in area were temoved from each of four normally grown plants of each variety in each plot at 6 a. m. and 5 p.m., respectively, on Aug. 21 (Fig.3). Seventy-two disks of leaf per variety w, ere dried as a set in an oven and weighed. Total nitrogen content of the leaves of representative four plants of each variety in the twq sowing methods was analysed by Kjeldahl method, to find the effect of competition on nitrogen metabolism.
