Two field experiments were conducted to observe the effects of Biochar, Mokusakueki and Bokashi application on soil nutrients concentrations, yields and qualities of sweet potato. Results showed that the effect of different fertilizers on soil pH and EC, potassium, magnesium and NO3 - -N concentrations was significant and Biochar gave highest soil pH and EC, potassium, magnesium and NO3 - -N concentrations in FS Center, but this effect of Biochar was not found in Mito farmland. Biochar and Mokusakueki treatments produced higher yields than conventional treatment in Mito farmland. Biochar showed significantly positive effect on higher number of tubercles, and Mokusakueki showed significantly positive effect on higher weight. Biochar and Mokusakueki gave positive effect on higher sugar content of sweet potato, furthermore, Biochar and Mokusakueki had positive effect on good apparent quality and higher marketability of sweet potato. The results of this study revealed that Biochar and Mokusakueki could increase yield, sugar content and appearance quality of sweet potato, which was conducive to bringing more economic profits for farmers, and improving food safety through using organic fertilizers, and finally promoting sustainable crop production.
