Optimizing fertilization practices can reduce the application of chemical nitrogen fertilizers, thereby enhancing crop yield while mitigating environmental impacts. In 2021–2022, we conducted field experiments in Inner Mongolia region, evaluating effects different methods on sugar beet growth and productivity. A two-factor randomized complete block design was applied for with rates (0, 75, 150, 225, 300 kg ha−1, denoted as N0, N75, N150, N225, N300, respectively) primary factor (single basal application, S1; split S2) second factor. The results indicate that increasing significantly enhances leaf growth, chlorophyll content, dry matter accumulation, metabolism, yield. comparison a nitrogen-free treatment, N225S1 treatment improved development resulting an average increase 29.36% over two years. Notably, by optimizing root–shoot balance carbon–nitrogen N150S2 achieved root yields comparable to N225S1. Therefore, our study demonstrates maintain reducing fertilizer inputs, providing valuable insights sustainable cultivation Mongolia, main growing area China.
