This study was conducted to investigate the effect of sta-green and activated carbon on leaf and stem growth of Agastache rugosa as it is affected by different amounts of sta-green and activated carbon. The results obtained are summarized as follows. Growth characteristics including plant height and leaf number were the highest when treated with 30% of sta-green. The weight of fresh leaf and stem of Agastaches rugosa was very low in control. Also, fresh weight of Angelica acutiloba was higher in 10% treatment of activated carbon. However, when the plants were grown in 10% activated carbon. all these promoters were the biggest. Sta-green and activated carbon can be utilized as a soil conditioner in agricultural crop areas.

This study was conducted to investigate the effect of activated carbon on leave production of Allium tuberosum. Growth characteristics including plant height and leaf length were the highest when activated carbon was added with 5%, suggesting that optimum amount of activated carbon was ranged from 5 to 10%. Weight of fresh green vegetable in Allium tuberosum was low in control. And fresh weight of Allium tuberosum was higher in 5% treatment of activated carbon. However, when the plants were grown in activated carbon of 5~10%, fresh yield of green vegetable of Allium tuberosum can be increased by using Activated Carbon. Activated carbon can be utilized as a soil conditioner in agricultural crop areas.
