In this experiment the growth process of the wild Japanese barnyard millet "Form A" and the paddy plant "Norin No.18" was traced. 1. The growth in height of the Japanese barnyard millet "Form A" is somewhat inferior than that of the rice plant "Norin No.18" in the younger stage, but thenceforth the former developes rapidly. In general, the inferiority in early growth of the wild Japanese barnyard millet is very important from the standpoint of suppression of this weed. 2. The velocity of increasing in the number of leaves of the main culm of the wild Japanese barnyard millet "Form A" is larger than that of the rice plant "Norin No.18"; and the former is superior in the number of leaves. 3. The rate of tilling of the wild Japanese barnyard millet "Form A" is somewhat larger than that of the paddy plant "Norin No.18", but the tillers of the latter are rather larger in number than those of the former. 4. The total number of leaves of an individual plant in younger stages increases very slowly in both the species, but thenceforth the number increases rapidly. The total number of leaves of one wild Japanese barnyard millet "Form A" is larger than that of the rice plant "Norin No.18".
