The field experiment was conducted during the fall agricultural season 2021-2022 in Department of Horticulture and Gardens, Al-Kut municipality; completed on 15 February. 2022, to study effect cultivar, fulvic acid, their interaction some broccoli's physical chemical properties. included two factors: cultivars, MATSURI, DOMO, JASSMINE, second factor has four concentrations which are: (0, 1, 2, 3) ml l-1. twelve treatments three replications, so total experimental units became (36). A factorial applied with a split-block system within Randomized Complete Block Design (R.C.B.D), results were statistically analyzed using statistical program (GenStat). compared LSD test at probability level 0.05. While JASSMINE cultivar superior wet weight main disc, dry diameter disc side if values ​​were (851.7 gm tablet-1,93.42 tablet-1,21.33 cm,147.25 tablet-1),respectively, MATSURI hybrid number tablets reached (5.00 plant-1 tablets). plants treated concentration (3) L-1 acid excelled content discs, Where (856.3 Tablet-1, 100.44 21.33 cm, 147.56 5.56 Tablet-1) respectively. dual between had significant effect, as treatment (990.7 disc-1, 124.00) tablet-1, 182.33 tablet-1)respectively.
