Abstract: In this study, we investigated the efficacy and suitability of five different nutrient solutions, including Biolife, BKFast, Hoagland, Hydro Umat F and Knop, on the growth and development of Impatiens walleriana in a hydroponic system. The investigated parameters were branch numbers, canopy diameter, leaf size, flower numbers, floral longevity, flower diameter and flowering time. The results showed that Knop and Hydro Umat F were the most suitable solutions for the growth of hydroponic Impatiens walleriana. The highest floral longevity (7.64 to 7.67 days) and largest flower diameter (4.68 to 4.71 cm) were obtained from Knop and Hydro Umat F solution treatment, respectively. Besides, compared to the other four solutions, using the Knop solution helped impatiens have the earliest flowers (27.14 days) and the highest number of flowers (54.86 flowers). Based on the results of our study, we recommend using the Knop nutrient solution with a TDS concentration range of 750-800 ppm and a pH level range of 5.5-6.5 for three-week-old Impatiens walleriana seedlings.
