A field experiment was conducted to evaluate effect of water soluble silicate fertilizer (WSS) application on rice plants with respect to comparing with powdery slag-originated silicate fertilizer (PSS) and granular one (GSS). The 30-day seedlings were transplanted on May 10, 2012. The plot size was , and the planting density was 15 hills . The standard application level was for WSS, for GSS, for GSS. The application rates were 50 %, 100 %, and 200 % of the standard levels. The soil and plant samples were taken after harvest on September 10. Strength weight of the stem was measured on the center of the 5-cm of the fourth internode. Nutrient contents and yield of grains and were evaluated. The strength weight of the stem was positively correlated with the silicate content of the stem with the highly significant of 0.601. The strength of the stem was satisfactorily enforced by application of 50 % WSS and GSS, and 100 % PSS. Application of 50 % or 100 % of WSS showed little difference in rice yield in comparison with application of 100 % of PSS or GSS. Therefore, application of of WSS would be recommendable for rice cultivation which enforced stem strength, and increased yield of rice.
