Abstract
This study was carried out to investigate a adequate strength of nuttient solution in production of marjoram and oregano by hydroponicsl Two herbs were grown for 40days with the strength of 0.5, 1.0, 2.0, and 3.0 dS${\cdot}m^{-1}$ in herb's nutrient solution developed by European Vegetable R & D Center, Belgium. the growth, vitamin C, and essential oil content of marjormam were higher in the treatment of 0.5 dS${\cdot}m^{-1}$ than the other treatments tested. But marjoram growtn with the sstrength of 20. and 3.0 dS${\cdot}m^{-1}$ had the highest mineral contents and essential oil content, respectively. Elevated strength of nutirent solution decreased chlorophyll content. In oregano, the growth was vest in the stength of 0.5, but withered in the strength of 3.0 The chlorophyll content was the lowest in the strength of 0.2dS${\cdot}m^{-1}$, while vitamin C contents had no statistical differences among treatments, Oregano grown with 1.0 dS${\cdot}m^{-1}$had the highest mineral and essential oil content, but the oil yield washighest in the treatment of 0.5 dS ${\cdot}m^{-1}$. In conclusion, the strength of 0.5 dS${\cdot}m^{-1}$ herb's nutrient solution was adequated in production of marjorma and oregano in hydroponicc system.
