Cucumber is a fruit-bearing plant which could produce cucurbitacin and lignan, <br /> <br /> the potential raw material for cancer treatment. However, the annual production <br /> <br /> of cucumber is relatively low at 477,976 tons per year. One of the reasons for the <br /> <br /> low productivity is the low absorption of organic nitrogen and the inefficiency of <br /> <br /> nitrogen usage for plant growth. Therefore, the aim of this study is to increase the <br /> <br /> productivity of cucumber with the application of silica-containing fertilizer onto <br /> <br /> the soil. The concentration of the fertilizer is 100, 150, 200, and 250 ppm. <br /> <br /> Parameters measured to determine the effect of the fertilizer are plant height and <br /> <br /> weight growth rate, Chlorophyll a content, fruit yield, fruit quality, and Vitamin C <br /> <br /> content of the fruit. The result of this study concludes that fertilizer application at <br /> <br /> 200 ppm gives the best biomass growth rate, chlorophyll content, fruit yield, and <br /> <br /> vitamin c content. Furthermore, the application of the fertilizer has no significant <br /> <br /> effect to fruit size. In conclusion, the cultivation of cucumber with liquid silica <br /> <br /> fertilizer with the concentration of 200 ppm could increase the growth, yield, and <br /> <br /> vitamin c content of the cucumber fruit
