Sowing season is a critical agronomic factor influencing the growth, yield, and quality of edamame (vegetable soybean). Based on existing studies and field observations, this paper systematically analyzes the effects of different sowing seasons on edamame growth characteristics, yield formation, and quality traits. The results indicate that appropriate sowing seasons significantly improve emergence rate, seedling vigor, and vegetative growth, thereby promoting balanced development during reproductive stages. Variations in sowing time also markedly affect yield and its components, including pod number, seed number per pod, and 100-seed weight, ultimately determining both single-plant and population yield. In terms of quality, sowing season influences protein and soluble sugar content, as well as sensory attributes such as flavor and texture, which are closely related to market acceptability. Furthermore, environmental factors such as temperature, light, and moisture interact with sowing time to regulate plant growth and productivity. Economic analysis demonstrates that optimal sowing seasons can enhance input-output efficiency and reduce production risks. A case study further confirms that region-specific optimization of sowing dates is essential for achieving high yield, superior quality, and stable production. This study provides a theoretical basis and practical guidance for optimizing edamame cultivation practices.
