Abstract
The effects of the nitrogen application rate of substrates and concentration of nutrient solution in hydroponics on the growth of rooted cuttings were investigated in Elatostema involucratum Franch. & Sav. The rooted cuttings were potted in vermiculite containing 0, 200, 400, or 800 mg per L of nitrogen fertilizer. The growth of transplants was similar in all concentrations 21 days after being potted. However, the growth of transplants with 400 mg per L was more favorable than that of the others 42 days after being potted. The rooted cuttings were grown hydroponically with a concentration of 0.25, 0.5, or 1 unit of standard nutrient solution. With 0.5 and 1 unit, death or leaf tip drying of transplants was observed. The optimal growth of transplants was observed with a concentration of 0.25 units.
