| The purpose of this experiment was to investigate optimal ionic concentration of nutrient solution for water culture of young welsh onion (Allium fistulosum). For the purpose of clarification of optimal nutrient concentration to maximize growth of young welsh onion, different nutrient concentrations of Yamazaki's solution for welsh onion seedling $(NO_3^--N;9.0,;NH_4^+-N;3.0,;PO_4^{3-}-P;6.0,;K^+7.0,;Ca^{2+};2.0,;Mg^{2+};2.0,;and;SO_4^{2-}-S;4.4me{cdot}L^{-1})$ which selected by prior experiment were treated as 0.6, 1.2, 1.8, and $2.4dS{cdot}m^{-1}$. Increments of fresh weight, dry weight and top length were the highest in 1.2 and, in the next, were placed by the order of 1.8, 2.4, and $0.6dS{cdot}m^{-1}$ The regression coefficients for the maximal growth of fresh weight of cv. 'Geurnjanguedaepa' and 'Tokyokuro' were $y=-42.091x^2+171.79x+11.047 (R^2=0.8946,; R=0.9458^*);and;y=-50.069x2+157.58x+15.414(R^2=0.9343,;R=0.9692^{**})$, respectively, and optimal EC levels according to regression coefficients were 1.68 and $1.57dS{cdot}m^{-1}$. As the conclusions, optimal nutrient levels far young welsh onion were $1.2dS{cdot}m^{-1}$ EC in the early growth stage and $1.6~l .7dS{cdot}m^{-1}$ in the later growth stage. |
