In oder to evaluate the effects of functional composts which include elvan, jade and loess, the growth and the yield of Chinese Cabbage and its content of sugar, nitrate and vitamin C were analysed. This study was conducted in lysimeter which was installed in the Experimental Farm of Dankook University. Total fresh weights of Chinese Cabbage were higher in the treatments of compost with mixture of elvan, jade and loess, while numbers of leaf was not increased in those treatments compared to control plot. Leaf length increased more than leaf width, specially in the plot of evlan treatment. Fresh weight of leaf blade and midrib in outer leaf was highest in the plot of elvan treatment among the 6 treatments. Sugar content in the Chinese Cabbage showed lower in the treatment of compost with mixture of elvan, jade and loess compared to control plot. Vitamin content in midrib was high in the treatment of compost with mixture of elvan, jade and loess compared to control plot. Vitamin content was high in leaf blade compare to those in midrib, and it showed highest value in the treatment of compost with mixture of jade. Nitrate concentration of leaf blade and midrib in the treatment of compost with mixture of loess was lowest at 2,021ppm and 2,235ppm respectively. It shows the effective function of mixture compost with jade, loess and elvan to decrease nitrate content in the Chinese Cabbage.
