The current study was conducted during the agricultural season (2019-2020) in the lath house that (covered with Saran and cloth) belonging to the Agricultural Research and Experiment Station at the College of Agriculture, University of Basrah, We sprayed Geranium Pelargonium hortorum L. with three a  concentrations (0, 50, 100) mg. L-1 of the organic fertilizer humic acid as well as three concentrations (0, 40, 80) mg. L-1 of vitamin B3 nicotine amide. Then, we investigated the response of Geranium plant for two treatments in n the vegetative ,flowering and root growth after three sprays of each treatment fertilizer humic acid and nicotine amide at (100 and 80) mg. L-1 respectively caused led to the improvement of flowering and root growth indicators, which included (flowering date, the length stalk of inflorescence, percentage of dry matter in inflorescences, length of main roots, number of main roots, percentage of dry matter in the root system). The present study indicated the important role of humic acid and nicotine amide in the  amelioration of flowering and root growth of geranium plant.
