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 determine feasibility of production system of Perilla frutescens leaf-stem by fertilizing of Sta-Green in pots. Germination rate of Perilla frutescens seeds collected in 2002 was 7%, also germination rate of seeds collected in 2003 was 62%, while germination rate of seeds collected in 2004 was above 93%. Seed germination rate of Perilla frutescens collected in 2004 were higher than seed gathering in 2002. Especially, plant growth and yield of Perilla frutescens grown in pot(The pots was filled with soil mixtures of Sta-Green and Peat Moss mixed with 40:60 ratio.) was the highest. These results indicate that leaf and stem production of Perilla frutescens can be improved by fertilizing of Sta-Green in pots.

This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by fertilizing of Sta-Green in pots. The results obtained are summarized as follows. Germination rate of Angelica acutiloba seeds collected in 2003 was 13%, while germination rate of seeds Collected in 2004 was above 91%. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than seed gathering in 2003. Especially, plant growth and yield of Angelica acutiloba grown in pot(The pots was filled with soil mixtures of Sta-Green and Peat Moss mixed with 45:55 ratio.) was the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by fertilizing of Sta-Green in pots and optimizing seed collecting time in greenhouse.
