Summary:This study was conducted to find out the optimum silicate fertilization for improving the quality and density of zoysiagrass (Zoysia japonica Steud.), the growth of zoysiagrass and changes in chemical properties of soil in field experiments treated with different levels of silicate fertilizer during 3 years from 2012 to 2014. An increase in the silicate fertilizer from 100, 200, to $400kg\;10a^{-1}$ led to a significant increase in the fresh and dry weight of shoots and stolons, the number of shoots and length of stolon, but were not significantly different between 200 and $400kg\;10a^{-1}$. Moreover, soil pH, EC and the contents of available $SiO_2$ were increased as the rate of silicate fertilizer application increased. Thus, these results demonstrated that the silicate fertilizer rate for maximum growth of zoysiagrass was $200kg\;10a^{-1}$ in consideration of improving growth of zoysiagrass and the chemical property of the soil. 들잔디의 품질과 줄기 밀도 향상을 위한 적정 규산질비료 시비량을 구명하기 위하여 본 연구가 수행되었다. 2012년부터 2014년까지 3년간 들잔디 재배지 포장시험을 수행하였다. 지상부와 지상 포복경의 생체중과 건물중, 지상부 줄기 개수, 지상 포복경 길이 등은 규산질비료 100, 200과 $400kg\;10a^{-1}$로 시비량이 증가함에 따라 수치가 증가하였다. 그러나 규산질비료 시비량 200과 $400kg\;10a^{-1}$ 처리구간에는 통계적으로 유의적인 차이를 보이지 않았다. 규산질비료 시비량이 증가할수록 토양 내 pH, EC, 토양 내 유효규산 함량이 높아지는 경향을 보였다. 들잔디 생육 증가 및 토양의 화학성을 고려한 적정 규산질비료 살포량은 $200kg\;10a^{-1}$로 판단되었다.
