Effect of Activated Carbon on Growth of Ginger (Zingiber officinale)

Activated carbon(AC) can be utilized as a soil conditioner in agricultural crop areas. This study was conducted to investigate the effect of AC on growth and yield of Ginger(Zingiber officinale) as affected by different amounts of AC. The results obtained are summarized as follows. Growth characteristics including plant height and leaf length were the highest when activated carbon added with $5-10\%$, suggesting that optimum amount of activated carbon was ranged from 5 to $15\%$. Growth and enlargement of the root were improved by $10\%$ AC with higher rhizome length and weight.
