Abstract
This experiment was carried out in a plastic house belonging to the olive nursery, the Department of Gardens and Afforestation, Amanat Baghdad for the agricultural season 2020 /2021 to study the effect of chemical fertilization (NPK) equivalent to four concentrations (0,50,100,150)mg.l-1 and foliar spray gibberellic acid (0,100,200)mg.l-1 and Benzyl Adenine (0,100,200)mg.l-1 in the growth and flowering of Angelina-class shrub flower plants. The plants were fertilized with NPK compound fertilizer equivalent to irrigation water throughout the trial period as needed, while the foliar spraying of plants by growth regulators gibberellic acid and benzyl adenine was done in succession, where the first spray was dated 1/12/2020 and the second spray age dated 5/1/2020 and the third workshop dated 3/2/2020. The experiment was carried out according to the Randomized Complete Block Design (R.C.B.D.) with three replications and the averages were compared using Duncan's multiple ranges test at a probability level of 5%.
