| The study was conducted in one of the glasshouses of the College of Agriculture at the University of Anbar in the city of Ramadi, located in longitude and latitude 33 and 25, to investigate the effect of adding humic substances and spraying with arginine amino acid on the vegetative and root growth of the Carissa plant. The experiment included two factors. The first factor was the humic substance at four concentrations, which are 0, 1, 2, and 3 mg L-1; the second was the amino acid arginine at three concentrations, 0, 3, and 6 mg L-1. The experiment was designed using a Randomized Completely Block Design (R.C.B.D) with three replications. The study showed a significant improvement in the interaction treatment between the arginine acid treatment A2 and the organic material treatment H3 in the rates of leaf area, leaf number, plant height, carbohydrates, nitrogen, root surface area, and root length. It reached 827.000 cm2, 17.333 leaves plant-1, 15.667 cm, 4.690%, 2.667%, 46.937 cm2, and 11.300 cm, respectively. |
