This study was carried out to investigate the effects of natural materials on quality and yield of radish. The GB10, chitofarm, chaff charcoal, and chaff charcoal sap were used as natural materials. The total plant weight, root weight, root length, and root width of radish in treatment with natural materials showed significant difference compared with control. The yield of radish in 1% of GB₁₀ treatment was increased 75% compared with control. The chemical components were increased in total plant of radish treated with natural materials compared with control. This appears that natural materials increase the quality of radish.
