This study was conducted to find out the effect of a lime stabilized slaughterhouse waste(LSW) on the growth of chinese cabbage and soil pH. Two levels of the lime stabilized slaughterhouse waste treatment, 169 and $338kg\;10a^{-1}$, with N-P-K fertilization were tested, and treatments of N-P-K and N-P-K with slaked lime were included in the experiment as a control. Fresh weight of chinese cabbage at harvest was not significantly different among the treatments. However, in the LSW treatment of $169kg\;10a^{-1}$, fresh weight of chinese cabbage was 5% higher comparing to the N-P-K treatment. Contents of N, P, and K in chinese cabbage were higher in the LSW treatments in comparison to the control treatments. Competitive inhibition of Mg uptake by Ca in the treatments of LSW and lime was apparent. Soil pH was increased by the application of LSW, and the increase in the LSW treatment of $169kg\;10a^{-1}$ was nearly the same as the soil pH increase in the slaked lime treatment. The lime stabilized slaughterhouse waste can be considered as a potential soil amendment for amelioration of soil acidity and supply of organic matter as well.
