Soybean (Glycine max L. Merrill) is a versatile legume with significant global importance in food security, nutrition, and industry. Native to East Asia, it has become a major crop, contributing 25% of the world's edible oil and two-thirds of global livestock protein concentrate. It plays a crucial role in crop rotation, improving soil health and preventing erosion. This review explores soybean's historical significance, botanical characteristics, geographical distribution, climatic influence, and reproductive biology. It also discusses advancements in genetic improvement and biotechnological applications, emphasizing transgenic soybean production and disease resistance efforts. Soybean is a key crop in many countries, including Brazil, the United States, Argentina, India, and China, with significant production areas and yields. It thrives in a range of climates and soils, with optimal growth in neutral to slightly acidic pH soils. Soybean's reproductive biology involves distinct stem growth habits and a unique flower structure. Recent advancements in genetic engineering and biotechnology have enhanced soybean traits such as disease resistance, yield, and drought tolerance. Future breeding strategies focus on improving yield stability, drought tolerance, and nutrient efficiency. Nanotechnology is also being explored to enhance soybean production and management. Overall, soybean remains a vital crop with significant potential for future agricultural development.Soybean (Glycine max L.
