    The effects of chemical fertilizers on crop growth and grain yield are relatively well known, but little is identified about their synergistic effects with foliar nutrition. The factorial experiment was arranged in a strip plot design with three chemical fertilizations at the rates of N150P105K75, N180P125K90 and N210P145K105 in the main plot, while sub-plots included four combinations of foliar feeding with carbamide-CO(NH2)2 with doses of 4.0, 8.0 and 12.0 kg ha -1 at the tillering, booting and heading stages of winter wheat (WW), respectively. Results indicated that the WW grain production was increased by 21.2% with foliar nutrition applied at 4.0: 8.0: 12.0 kg/ha regime under N180P125K90 chemical fertilization norm compared to the control, exhibiting the highest yield among tested variables. The total grain yield of WW increased with an increase in chemical fertilization norms, providing a significant increase in the fodder yield parameters as well.Increasing chemical fertilization increased the grain quality indices, but the highest indicators were observed under the moderate (N180P125K90) chemical fertilization norm applied with the foliar nutrition (4.0: 8.0: 12.0 kg/ha regime). In overall, this innovative farming technique has the potential to limit land degradation and create sustainable farming systems, while improving biodiversity conservation and ecosystem services that require less chemical fertilization.
