Megjegyzések:	Sorghum bicolor (L.) Moench is scientifically known as a highly adaptable cereal crop with a high nutritional value, including significant amounts of crude protein and trace components. Crude protein encompasses various amino acids essential for growth, development, and maintaining quality. Trace elements play a crucial role in metabolism and activating enzymes. By examining the levels of crude protein and trace elements in various Hungarian sorghum cultivars, the research aims to show how nitrogen?s impact varies across different cultivars. The assessment research focused on six chosen cultivars: Zádor, Alföldi 1, ES Albanus, Albita, and Farmsugro180. These types displayed different hues, including red, red/brown, and white. The cultivar ES Föehn, developed by Lidea Seeds, served as the benchmark for European standards. The elements N, Fe, Zn, Cu, and Sr were selected for the intended investigation. The treatment consisted of a control group that did not get any nitrogen fertilizer and a treated group that received nitrogen fertilizer in the form of ammonium nitrate (Péti-só, 27% N). The treated group was managed with a 60 kg·ha-1 dosage in the experimental field. The findings revealed variations in the concentrations of elements depending on the different kinds within each category. Most of the analyzed groups exhibited a statistically significant p-value of less than 0.05, as determined by the variance of non-parametric data for Fe, Cu, Zn, and Sr. For example, Zádor exhibited abundant microelement contents, such as N (15.3 mg·kg-1), Fe (46.2 mg·kg-1), Cu (3.5 mg·kg-1), and Zn (23 mg·kg-1). Strontium (Sr) mineral showed a strong correlation, with a correlation copper of r = 0.66. The variety of mineral and protein levels seen in the examined cultivars is highly recommended as a valuable source of nutritious plant-based dietary resources, especially for developing concentrated protein sources. According to the findings, brown and red grain pericarp varieties have been identified as lucrative raw materials for investments in the industrial sector, mostly because of their high crude protein qualities.

Megjegyzések:	How crop biodiversity adapts to drought conditions and enhances grain yield became the most important issue facing agronomists and plant breeders at the turn of the century. Variations in genetic response, inadequacy of nutrients in the soil, and insufficient access to nutrients are factors that aggravate drought stressors. The development of screening tools for identifying drought tolerance is important in the deployment of durum wheat varieties suited to drought-prone environments. An experiment was conducted to evaluate durum wheat varieties under a range of nutrient supplies in naturally imposed drought conditions. The treatments consisting of two nitrogen regimes (i.e., control and 60 kg ha?1), four durum wheat varieties, and three types of nutrients (control, sulfur, and zinc) that were arranged in a split-split plot design with three replications. Both foliar-based sulfur and zinc fertilization were employed at the flag leaf stage, at a rate of 4 and 3-L ha?1, respectively. The results showed a significant (p < 0.05) genetic variation in chlorophyll concentration, grain protein content, tillering potential, and leaf area index. Varieties that contained better leaf chlorophyll content had improved grain yield by about 8.33% under 60 kg/ha nitrogen. A combined application of nitrogen and zinc at flag leaf stage significantly improved grain yield of Duragold by about 21.3%. Leaf chlorophyll content was found to be a more important trait than spikes per m2 to discriminate durum wheat varieties. Foliar application of sulfur increased the grain yield of drought-stressed plants by about 12.23%. Grain yield and protein content were strongly correlated with late-season SPAD readings. Significant (p < 0.05) correlation coefficients were obtained between normalized difference vegetation index, leaf area index, grain yield, and protein content with late-season chlorophyll content, revealing the importance of chlorophyll content in studying and identifying drought-tolerant varieties.
