Fulvic acidAbstract

In order to evaluate the effect of humic acid (HA), fulvic acid (FA) and Kristalonon quantitative and qualitative characteristics of geranium, an experiment was conducted in different fertilizer levels as factorial arrangement in randomized complete block design with three replications in greenhouse condition at Greenery Clinic of Tehran Municipality, Region 21st. Two levels of treatments were sprayed on plants including humic acid, fulvicacid, and pink Kristalonwith concentrations of 2, 4 and 1 mg/lrespectively,and control treatment. Certain traits were measured including plant height, leaf area, number of leaf, internodes length, and sub-branch number, stem and bush wet and dry weight, chlorophyll and soluble sugar. The results indicated that the application of humic acid and fulvic acid had significant effect on all of the measured traits. The treatment of Kristalon had significant effect on all of the measured traits except for the number of leaf, dry weight of branch and length of the branch. The application of humic acid 4% proved to have the highest effect on all of the traits under examination.
