This study evaluated the effects of ammonium nitrate and ammonium sulfate fertilization on winter wheat yield and grain quality under field experimental conditions. Grain yield and major quality parameters, including protein content, gluten content, thousand kernel weight, and test weight, were determined. Nitrogen was applied at five fertilization rates: b1 - N0, b2 - N50, b3 - N100, b4 - N150, and b5 - N170 kg N ha−1, to assess crop response to increasing nitrogen supply. The results indicated that both nitrogen source and application rate significantly affected grain yield, with
higher nitrogen rates promoting increased productivity. Nitrogen fertilization also exerted a pronounced effect on grain quality traits, leading to higher protein and gluten contents, while thousand kernel weight and test weight showed distinct responses depending on nitrogen form and dose. Overall, the study demonstrates that optimizing nitrogen source and application rate is essential for achieving a balanced improvement in winter wheat yield and grain quality under intensive cropping systems. These findings provide practical guidance for nitrogen management strategies aimed at sustainable wheat production systems.
