ABSTRACT: <br /> <br /> <br /> A research on the use of vermi-manure from live stock feces on latosol soil has been conducted, using mustard green (Brassiai junaea (L.) Czernj. & Coss) as indicator. The objective of this research was to evaluate the effect of fertilizer of vermi-manure originated from the various live stock feces on N and C/N-ratio of latosol soil, nitrogen absorption, chlorophyl content, and biomass of mustard green, as well as to analyze the economic value of mustard green The types of vermi-manure used in this research were: venni-manure originated from feces of cows, horses, sheeps, and chickens. A dosage of 10 tone/ha of vermi-manure was used in each treatment The result showed that all types of vermi-manure increased the N content and decreased C/N-ratio of latosol soil. They also increased the N absorption, chlorophyl content, and mustard green biomass. Among the four types of vermi-manure, the cow-originated vermi-manure provided the best influence, both on soil and plant. The highest percentage of the profits of the mustard green farming, that was 58,44 %, was obtained by using the vermi-manure originated from cow feces.
