초록

The dry weight of mother plants' leaves had the highest increase rate in both NS (single-use) and NS+EM (mixed-use) mixed with NS 0.8 (customary use). In seafood amino acid fertilizer (SAF) application, the increase rate was highest in SAF solution at a 300-fold dilution. Mother plants' crown diameter, plant height, leaf length, leaf width, petiole length and leaf number showed the greatest growth amount when NS 0.8 (customary use) was mixed to NS (single-use) or NS+EM (mixed-use) solution. The growth was highest in SAF solution diluted 300 folds, but lowest in SAF solution diluted 100 folds. Of all inorganic nutrients, excluding sulfur, total amount of nitrogen, available phosphorus, potassium, calcium and magnesium had the highest increase rate in both NS (single-use) and NS+EM (mixed-use) with the treatment of NS 0.8 (customary use). Total nitrogen, in particular, was increased by 3.1% in NS 0.4, 6.0% in NS 0.8, and 4.5% in NS 0.8 with the application of NS+EM at a 500-fold dilution compared to NS alone. Total nitrogen amount showed the highest increase rate in SAF solution diluted 300 folds. Total nitrogen, available phosphorus, calcium, magnesium and EC in soils applied with culture solutions (NS, NS+EM) had increasing tendencies after fertilizer application. The results were comparable to those of SAF treatment. The increase rate of each inorganic nutrient composition declined in soils applied with NS+EM solution diluted 500 folds compared to NS alone.
