This study was carried out during growthing season of 2014-2015 at the Agriculture college-Basrah university to investigate effect of spraying magnesium at concentration of (0.0, 0.5, 1, 1.5 mgL⁻¹) and agrosine at concentration (0,25,50, and 57 ml L⁻¹) in vegetative growth  characterizes of seedied sour orang seeding. The result showed that spraying Mg (1.5 mg L⁻¹) and Agrosine (75ml L⁻¹). recorded significant increasing  in seedling length, stem diameter, number of new growing shoots, number of leaves, leaf area and concentration of nitrogen, megnisum and total chlorophyll pigment  and total carbohydrate of leaf .The result showed also that the combination between (1.5 mg L ⁻¹ + 75 ml L⁻¹) gave significant increase in all studied characterizes.
