Abstract
The field experiment was conducted during the fall agricultural season 2021-2022 in the Department of Horticulture and Gardens, Al-Kut municipality; the experiment was completed on 15 February. 2022, to study the effect of the cultivar, fulvic acid, and their interaction on some broccoli's physical and chemical properties. The study included two factors: cultivars, MATSURI, DOMO, JASSMINE, and the second factor has four concentrations of fulvic acid, which are: (0, 1, 2, 3) ml l-1. The experiment included twelve treatments and three replications, so the total experimental units became (36). A factorial experiment was applied with a split-block system within the Randomized Complete Block Design (R.C.B.D), and the results were statistically analyzed using the statistical program (GenStat). The results were compared using the LSD test at a probability level of 0.05. The superiority of the hybrid MATSURI in total soluble solids (TSS) in the pink discs was (23.64 %). At the same time, the JASSMINE cultivar was superior in total yield of the experimental unit and the percentage of chlorophyll in the leaves at values were (25.01 kg plant- 1, Spad 84.33), respectively.
