Effects of fulvic acid and iron nano chelate on some morphological and biochemical characteristics of Gerbera jamesonii cv. Dune

In order to investigate the effect of fulvic acid and iron nano chelate on growth and biochemical characteristics of Gerbera, (Gerbera jamesonii cv. Dune) an experiment as completely randomized design with two factors fulvic acid with 4 concentrations of 0 (control), 50, 100 and 250 mg/l as drench and iron nano chelate at 4 concentrations of 0 (control), 1, 2 and 4 gr/l as foliar application, with three replications in greenhouse conditions in pot and in hydroponic conditions was performed. The result of this study showed that interaction effects of fulvic acid and iron nano chelate increased chlorophyll index, leaf length, the number of leaves and total dry weight (stem and head of flower) compared to control. Stem fresh weight and stem diameter were not affected by these treatments
