This study was carried out to investigate the effect of microbial fertilizers on yields of Chinese cabbage(Brassica campestris L.). Six microbial fertilizers, MPK+Husk+Palma, Husk+Palma, MPK+Compost, Compost, Bio livestock cattle system(BLCS) cattle dropping, and Tomi, were used. All of the microbial fertilizers were very effective to increase yields of Chinese cabbage. As a result of analysis of plant chemical components, MPK+Compost treated plot showed higher concentrations of Fe and Zn than other microbial fertilizers plot. In a chemical components of soil, concentrations of K, Mg were increased with Tomi treatment, however, the other concentrations of plant and soil chemical components were not different. In a microbial properties of soil, Tomi, Husk+Palma, and MPK+Husk+Palma treated plots increased in numbers of total bacteria and bacillus. Tomi treated plot increased in numbers of actinomycetes and fungi, also. The other microbial properties of soil were not different, however. The microbial fertilizers may affect the useful microbial properties, therefore, it would be increase yield of Chinese cabbage treated with them.
