The present study was undertaken to investigate, according to the previous paper, how to change the development of branching, curvatures and the shooting angles of roots in successive nodes when wheat and corn were planted under the different kinds of soil and manure. The following results were obtained: 1. The height and number of tillers were greater in compost plot and heavy fertilized plot and were inferior in clay plot. 2. The curvature and branching of rots were more developed in compost plot and sand plot but were meagerest in clay plot (Fig. 1, 2). Therefore number and length of secondary and tertiary roots were superior in compost plot and sand plot than in clay plot. 3. In compost plot the rot angles were large and elongated horizontally, but in sand plot the angles were smaller (Fig. 3, 4). From these results, it can be said that the root angle is influenced by soil conditions and there is a tendency that the root angle is larger when the plant is more grown.
