The experiment ran from the middle of February until the start of November 2023 under the plant canopy of the Department of Horticulture and Landscape, College of Agriculture, University of Kerbala. The study employed a Randomized Complete Block Design (R.C.B.D.) as a factorial experiment, with two pomegranate varieties (Yamani and Bashkan) as the first factor and various combinations of natural and chemical rootings as the second factor. These included extracts of moringa leaves (M0, M1) and licorice roots (L0, L1) at concentrations of 0 and 15 g L-1 each, as well as indole butyric acid at a concentration of 0 and 10 mg L-1 (B0, B1). The majority of the root features of the resultant seedlings demonstrated that, overall, the Bashkan variety outperformed the Yamani variety; however, this superiority varied when combined with other rooting combinations. Between the rooting stimulant combinations utilized in the study, the cuttings' dipping results differed. When it came to the quantity, size, and fresh and dry weight of the root system, indole butyric acid in combination with B1M0L0 performed better. It resulted in 250.000 root seedlings-1, 2.270 cm3, 20,680 g, and 6,650 g, respectively. In contrast, the B0M0L1 licorice root treatment demonstrated superior root length, reaching 38,100 cm. Both the percentage of rooting and the average root diameter were the largest in the combination including both extracts, B0M1L1, reaching 5.170% and 1.603 mm, respectively. Given that natural extracts have outperformed chemical radicals in the majority of the rooting qualities under study—such as licorice root extract and moringa leaf extract—it is possible to conclude from the aforementioned results on their suitability for usage as an alternative.
