Effects of silica upon the growth of paddy rice plants grown in pots (soil. culture) with various heights of level of underground irrigation, were investigated. Soil employed in those experiments contained a small amount of available silica. For the silica plot (A), silica gel (sodium silicate neutralized by HCl), and for the silica plot (B), slag (both containing SiO_2 3.35g per pot) were given. The heads of underground irrigation were about 19 cm (a), about 10.5 cm (b) and about 2 cm (c) above the pot bottom in every plot. The results obtained were as follows: Heading time in the treated plots, (A) and (B) was earlier than that in the control plot. Air-dry weights of the leaf and stem and of the panicle in (a) and (b) of the treated plots (A) and (B) were larger than those of the control with no application of silica, but in (c) they were not so. Almost the same tendency was observed concerning to the amount of silica in the plants. From the results obtained, it was recognized that application of silica showed good effects on the growth of rice plants when underground water level was high to Some extent.
