Abstract:

Impatiens walleriana L. is one of the most important plants used in landscape throughout world. The aim of the study was to determine the effects of two dose (0, 40 mg kg-1) of fulvic acid (FA) and four doses (0, 40, 80 and 120 mg kg-1) of humic acid (HA) treatments on growth parameters of Impatients walleriana L. The parameters investigated was the number of buds, plant height, number of main shoots, the number of secondary shoots, plant diameter, flowers number, root length, fresh root weight, dry root weight, fresh leaf weight and dry leaf weight, respectively. The highest plant height (11.3 – 9.2 cm) and flower number (12.6-7.6 number) was obtained from treatments 40 mg kg-1 of FA and HA respectively. The results showed that 40 mg kg-1 both fulvic and humic acid dose treatment was the most effective in particular on flowering and plant growth parameter when compared to with control plant.
