Megjegyzések:	Monitoring nitrogen utilization is crucial in agricultural practices, emphasizing the interrelationship between soil health, nutrient management, and human health. The study was conducted to evaluate the impact of N fertilizer on the nutritional characteristics of diverse S. bicolor varieties, namely Alfoldi ? 1, ES Foehn ? (Lidea Seeds) with a red pericarp, ES Albanus, Albita, and Farmsugro 180 (all white varieties), the study was conducted in sorghumproducing areas where the crop is non-native. Specifically, the study investigated two soil types: loam clay and sandy soil. Furthermore, the respective varieties were grown under N (27% N CAN) fertilizer conditions, involving 60 kg/ha? 1 and 120 kg/ha? 1 of the treatment rates applied at each experiment site. We measured the specific element concentration in each sample using the Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) technology. Certainly, the results demonstrated that the different S. bicolor varieties had unique nutritional characteristics attributed to several factors such as soil type, variety, and treatment, which showed a significance value of (P < 0.05). The findings demonstrated that the treatments had distinct impacts as stimulators and inhibitors for certain elements. Specifically, the application of 120 kg/ha? 1 negatively affected the levels of particular elements, such as Ca mg/kg? 1 , in loam clay and sandy soil. The statistical analysis of trace microelement variance did not show a significance value (P > 0.05) when considering the year factor, which supported the data analysis`s reliability and accuracy. In summary, to enhance the nutritional value of sorghum grain and supply nutrient-rich food choices for individuals, consider factors such as fertilizer response, nutrient uptake by grain, element mineral accumulation, and advisory variety. Additional research could enhance the nutritional properties of sorghum to provide the required dietary stuff, such as grain processing, which can render sorghum a proper addition to a healthy and balanced human diet.

Megjegyzések:	Sorghum bicolor (L.) Moench is an increasingly important crop grown in many countries as a food source due to its excellent nutritional value, drought and pest resistance, and gluten-free properties. In this study, the bioactive profiles and antioxidant potentials of brans of six sorghum varieties were evaluated using spectrophotometric methods. The effects of weather and environmental conditions and different nitrogen nutrition were also evaluated. The bran of red varieties contained a higher amount of polyphenols and tannins and exhibited higher antioxidant capacities than the bran of white varieties, with the exception of one red genotype. The highest total polyphenol contents were measured in samples from two red varieties (Zádor, Alföldi1) with 1084.52 57.92 mg 100 g??1 GAE and 1802.51 121.13 mg 100 g??1 GAE values, respectively, while condensed tannin content varied between 0.50 mg g??1 and 47.79 mg g??1 in sorghum brans. Red varieties showed higher antioxidant activities/capacities with 70?281 mol TE g??1 and 71?145 mol TE g??1 for DPPH and TEAC. Correlation analysis showed a strong interaction between DPPH, TEAC, and the amounts of polyphenols and tannins, but not with FRAP values. In conclusion, red-colored varieties are a good source of polyphenols, but seed color alone is not enough to determine the nutritional value of a genotype, and the environmental conditions greatly affect the bioactive profile of sorghum.
