To assess the application effect of liquid pig manure(LPM) fermented for more than 6 months, the growth, yield and quality of tomato(Lycopersicon esculentum MILL) cultivated by the fertigation management were investigated from April 2008 to August 2008 in plastic film house. Then soil of plastic film house was analyzed to find on changing of chemical property. The treatments of tomato cultivation were composed with 4 plots as control(recommended chemical fertilizer amount), Control 1/2 + LPM 1/2, LPM 1/2, LPM(recommended LPM amount). The nutrient substances in LPM were N 5.1 g kg-1, total P 1.9 g kg-1and potassium(K) 8.9 g kg-1, and level of heavy metals appropriated in accordance with liquid fertilizer manufacturing standards. In result of soil chemical property, EC was increased from 2.15 dS m-1 to 2.23 dS m-1 at Control and LPM plots. Also, contents of Avai. P2O5, Ex. Cations, and NO3--N were more accumulated than before experiment in soil of all treatments. There was not significant on results of height and width of tomato plant among 4 treatments, but these results were highest at control. The yield of LPM plot was heaviest as 8,871 kg 10a-1 among 4 treatments and had increased 4% yield than control(8,530 kg 10a-1). However the rate of tomato goods(150～250g) was order as Control(72.3%) > LPM(70.9%) > Control 1/2 + LPM 1/2(68.3%) > LPM 1/2(61.8%). Consequently, the LPM application amount could be recommended as chemical fertilizing amount standard for tomato fertigation cultivation.
