This study was conducted to investigate the effects of natural materials such as GB<sub>10</sub>, chitofarm, chaff charcoal, and chaff charcoal sap, on quality and yield of chinese cabbage. Natural materials were treated on seeds, soil, and leaves. The total plant weight, head weight, head length, head width, leaf length, leaf width, and sugar content of chinese cabbage in treatment with natural materials showed significant difference compared with control. The yield of chinese cabbage in GB<sub>10</sub> soil treatment and 1% GB<sub>10</sub> leaf treatment was increased 53% compared with control. The total nitrogen, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, CaO, MgO, Na<sub>2</sub>O, and Mn in total plant were analyzed. The chemical components were increased in total plant of chinese cabbage treated with natural materials compared with control natural materials increased the quality of chinese cabbage.
