The study was conducted in the fields of the Department of Horticulture and Landscape Engineering / College of Agriculture / University of Kerbala, Al-Hussainiya District for the winter agricultural season 2024. The study was implemented as Factorial experience according to the Randomized Complete Block Design (R.C.B.D) with three replicates. Two factors were added: vermicompost, a ground addition, at four concentrations (0, 2, 4, and 6 ml L-1), and boron, using a flower spray at four concentrations (0, 25, 50, and 75 mg L-1). The results showed that adding vermicompost at a concentration of (6 ml L-1) and spraying with boron at a concentration of (50 mg L-1) had a significant effect on all vegetative characteristics (plant height, diameter, number of leaves, leaf area, and number of shoot branches). The bilateral interactions between the two study factors had a significant effect on all vegetative characteristics, especially at the fertilizer level. 6 (ml L-1 )- and spraying with boron at a concentration of (50 mg L-1 ) - which gave the highest rates of plant height of )72.20 cm( compared to the control treatment, which recorded )28.02 cm(, and the stem diameter was )28.496 mm( compared to the control treatment, which recorded )22.82 mm(, and the number of leaves was )210.40 leaves per plant-1 (compared to the control treatment, which recorded )98.30 leaves per plant-1(, and the leaf area was )79.37 cm2 (compared to the control treatment, which recorded )48.84 cm2(, and the number of branches was )9.267 branches per plant-1 (compared to the control treatment, which recorded )3.60 branches per plant-1(.
