Given the global significance of the potato plant and Iraq's low productivity, the finest techniques and technologies must be applied to boost output and enhance quality. One of these strategies is to utilize nanofertilizers instead of conventional fertilizers to speed up and make it easier for nutrients to enter the plant. Because of the high salinity and resulting low nutrient availability in Iraqi soils, foliar spraying is a potential alternative for providing nutrients to plants. Another good substitute that can raise agricultural output is nano-fertilizers. In the Babil Governorate, the primary plots were planted and distributed with five different varieties of potatoes (Arnova, Arizona, Revera, Burren, Sifra)). Nano-fertilizer (macronutrients + micronutrients) was applied to them in the secondary plots at three different concentrations (0, 1, and 2 g liter^-1). The experiment was carried out using a completely randomized block design using a split-plot arrangement. The experiment was repeated three times, and the studied indicators were measured at the end of the experiment. The results of the experiment demonstrated that the Arizona variety had the greatest success in most vegetative traits, including the number of stems that grow in the air, the number of leaves per plant and the area of the leaf. Plant^-1 also had a superiority in the trait of the marketable yield of 22.27 tons Ha^-1 is the small-fertilizer that has a concentration of 1 g. L^-1 had a significant impact on the number of aerial stems per plant and the number of leaves per plant. The fertilizer with a concentration of 2g.L^-1 had the greatest effect on the dry matter percentage in the tubers and the percentage of protein in the tubers, while the variety Arizona had the greatest number of aerial stems per plant, the marketable yield, and the percentage of protein in the tubers.
