| This experiment was conducted to investigate the effects of concentration of NO$_{3}$$^{[-10]}$ , $K^{£«}$ and $Ca^{£«£«}$ in nutrient solution on the seedlings growth of ¡®Mudeungsan¡¯watermelon. Seeds were sown on March 16, 1997. NO$_{3}$$^{[-10]}$ , $K^{£«}$ and $Ca^{£«£«}$ was treated with three different levels, respectively, NO$_{3}$$^{[-10]}$ = 106, 206, 406ppm; $K^{£«}$ = 150, 200, 400 ppm; $Ca^{£«£«}$ = 150, 200, 400 ppm. Plant growth was investigated at four-days interval in 10 days after treatment. Increasing N concentration in the nutrient solution increased the plant height, leaf area, number of leaves, fresh and dry weight of shoot while high concentration of K and Ca in the nutrient solution decreased the seedling growth in terms of leaf area, leaf dry weight. The uptake of N, K and Mg in petiole sap was positively affected by the adding of 206 ppm of nitrate, 150 ppm of potassium and 200 ppm of calcium levels, respectively. The P and Ca uptake in petiole sap was not affected by the N and K concentrations in the nutrient solution while K concentration above 200 ppm decreased the N and Mg content in petiole sap. High concentration of Ca in the nutrient solution increased the Ca content in petiole sap while Ca concentration above 200 ppm decreased the N content. |
