This study explores advancements in optimizing maize planting density and fertilization strategies to enhance maize yield and resource use efficiency. By synthesizing current research findings, it highlights that high-density planting combined with precise fertilization management can significantly improve maize growth and yield. High-density planting can intensify competition among plants, requiring tailored fertilization strategies to prevent resource waste and environmental pollution. The study summarizes practices such as split nitrogen application, effective use of phosphorus and potassium, slow-release fertilizers, and foliar fertilization, and emphasizes the importance of sustainable fertilization management in reducing greenhouse gas emissions. The research suggests further studies on soil health and nutrient efficiency optimization to achieve highly productive and environmentally friendly agricultural production.
