In recent years, many research studies have conducted to find ways to improve agricultural products and eliminate chemical fertilizer pollutants. In order to increase the yield of plants and reduce the consumption of animal food resources, it is necessary to use new agricultural techniques. Organic-based synthetic fertilizers such as nano chelated iron can contribute greatly to improving the nutritional system of plants and reducing the need for chemical fertilizers. Nano fertilizers are easily absorbed by plants and are more effective than conventional chemical fertilizers. On the basis of this information, this study was conducted to investigate the nutritional value of lettuce and its ability to absorb micronutrient elements. The study was conducted at Tabriz University in 1400-1401 as a completely randomized design in three repetitions. Three levels of nano chelated iron (0, 0.5 and 1 g/L) were used to investigate the effect of nano chelated iron on lettuce plant absorption of micronutrients. Nano chelated iron significantly increased the levels of secondary metabolites, including total phenols and flavonoids, as well as lettuce's antioxidant capacity as compared to control samples. Additionally, the results indicated that larger concentrations of nano chelated iron led to higher levels of total protein, soluble sugar, and free amino acids among lettuce plants compared to the control sample. It has been shown that micronutrients such as iron, calcium, zinc, potassium, and phosphorus accumulate in the roots and shoots of lettuce plants with the increased application of nano chelated iron to lettuce plants. This increase was greater in plants treated with higher concentrations of nano chelated iron. As a result of this study, the nano chelated iron was shown to increase plant primary and secondary metabolites, as well as provide iron and micronutrients for plants.
