Two field experiments were executed to study the seed priming, foliar spray of some Nanoparticles, gibberellic acid, and their interactions in the productivity of sugar beet cv BTS 105 under the conditions of the salt-affected soil. Each field experiment was including three factors in split-split plot design with three replications. The main plots were assigned to the methods, the rates of nanodomains were arranged randomly on the sub-plots and the concentrations were distributed in sub-sub-plots. Each sub-plot included six ridges 0.5 meters apart and 3.50 meters in length, The findings indicated that plants that received the combined application method (foliar spray + seed priming) were the most effective followed by foliar spray application alone the seed priming addition method alone, where the best performance with all studied characters, where plants were treated with TiO₂NPs at a rate of 100ppm priming+200ppm spray and AgNO₃NPs at a rate of 30 ppm priming +75ppm spray increased significantly white sugar yield, total soluble solids content (T.S.S.), sugar content (SC), white sugar yield (WSY), Extraction coefficient of sugar (ECS) and white sugar content (WSC) as compared with control treatments. In the contrast decreased significantly potassium, α- amino nitrogen, and sodium in sugar beet root.
