| This study was conducted to evaluate the effect of different surfactants on the fertilizer reduction and increase of the mineral nutrients uptake of lettuce (Latuca sativa L. 'Hanbatchungchima') in deep flow technique culture. The measured items from lettuce leaves expanded fully were growth, photosynthetic and transpiration rate, and mineral nutrient content K, Ca and Mg, respectively. The highest growth were observed at $0.3mg{cdot}L^{-1}$ polyvinyl alcohol (PV4-95) treatment, including lettuce grown in the half strength of nutrient solution. The highest photosynthetic rate, transpiration rate and mineral nutrient content were observed at $0.3mg{cdot}L^{-1}$ calcium lignosulfate (CLS) treatment. Therefore, high-quality leaf lettuce production could be achieved by apply proper surfactants PVA-95 and CLS, which can cut down the total amount of fertilizer and increase uptake of mineral nutrients. |
