  Sustainable agricultural practices are vital for ensuring global food security. Factors such as soil, weather, and agronomic practices, including nutrient supply and tillage systems, play key roles in sustainable crop production. A field experiment at the Hungarian University of Agriculture and Life Sciences in Godollo, Hungary, assessed the impact of primary soil tillage methods and foliar nutrient supplementation on winter barley yield and traits. Using a split-plot design with three replications, the study examined four nutrient treatment (control, Bio-cereal, bio-algae, and MgSMnZn Blend) and two tillage methods (plowing and cultivator). The obtained results indicated no significant influence of tillage treatments on SPAD value, leaf area index (LAI), plant height, or spike length. However, nutrient treatments significantly (P<0.01) affected LAI, plant height, and thousand kernel weights. Both nutrient and tillage treatments significantly (P<0.01 and P<0.05) influenced tiller number and grain yield, with significant (P<0.01) interaction effects observed for grain yield and kernel weight. The combination of Bio-cereal nutrient treatment with plowing tillage produced the highest values across parameters. Thus, integrating bio-cereal nutrient supplementation with plowing tillage is better for optimizing winter barley yield.

  The ever-growing world population entails an improvement in durum wheat grain yield to ensure an adequate food supply, which often gets impaired by several biotic and abiotic factors. Integrated nutrient management, such as nitrogen rate × foliar zinc × sulphur fertilization combined with durum wheat varieties were investigated in order to examine the dynamics of yield and yield related physio-morphological traits under drought conditions. The four durum wheat varieties, three-level of nutrient supply (i.e. control, sulphur, and zinc), and two nitrogen regimes (i.e. zero and 60 kg ha⁻¹) were arranged in split-split plot design with three replications. Zinc and sulphur were applied as foliar fertilisation during the flag leaf stage, both at a rate of 3 and 4 liters ha^-1, respectively. Results showed existence of genetic variability for grain yield, plant height, NDVI, SPAD and spike density. Foliar based application of zinc and sulphur at the latter stage improved the plant height. Nitrogen fertilized varieties with lower spike numbers showed to better yield formation. Co-fertilization of nitrogen and zinc improved grain yield of responsive varieties like Duragold by about 21.3%. Spikes per m² were statistically insignificant for grain yield improvement. It could be inferred that the observed positive effect of sulphur, nitrogen and zinc application on physio-morphology and yield formation substantiates the need to include these essential nutrients in the cultivation system of durum wheat.

  Maize plant response to plant density is an essential agrotechnical factor used for determining grain yield. Three plant densities (60,000 ha^-1, 72,500 ha^-1, and 85,000 ha^-1) were used in this study to ascertain the effect of photosynthetic parameters and grain yield. Results show a significant difference in the photosynthetic parameters (SPAD, NDVI, LAI) and plant height for plant density of 85,000 ha^-1. Grain yield and stem diameter were not significantly affected between the different plant densities.
