This study explores fertilization strategies aimed at achieving high and stable wheat yields through field experiments. We evaluated the roles of nitrogen, phosphorus, and potassium fertilizers in wheat development, and systematically designed a field trial with appropriate site selection, treatment replications, and statistical methods. Particular attention was given to optimizing nitrogen application through split and stage-specific fertilization, and to the effectiveness of integrated nutrient management, including the use of micronutrients and slow-release fertilizers. We also assessed the environmental and economic implications of fertilization schemes and conducted a regional case study to validate our approach. The results demonstrated notable yield improvements and resource use efficiency. This study highlights the potential of tailored fertilization schemes in stabilizing wheat yield while balancing environmental sustainability and economic viability, and provides practical guidance for future nutrient management strategies and policy development. Keywords Wheat yield; Fertilization scheme; Field experiment; Nitrogen optimization; Sustainable agriculture 1 Introduction Wheat is the most widely grown and consumed crop in the world. It is the main food for billions of people every day and plays a critical role in global food security. Wheat can adapt to different climates and various soils, and its nutrient-rich nature makes it very important in feeding people around the world and driving the agricultural economy (Chen et al., 2018; Jiang et al., 2023). Now, the world population has been growing, and the problem of food is becoming more and more urgent. To solve this problem, wheat must be both high-yield and stable. Only in this way can the food needs of more people be met while reducing the impact of climate change and resource shortages. Increasing yield while keeping it stable is the key to achieving a stable food supply and promoting sustainable agricultural development, especially when environmental pressure increases, and minimizing damage to the ecology (Ma et al., 2022; Hu et al., 2023). This study mainly summarizes the results of some recent field experiments, which are all centered on how to make wheat high-yield and stable through fertilization. We compared a variety of different fertilization methods, including the use of chemical and organic fertilizers, improving fertilizer application time and nutrient management methods. Through these experiments, we want to find some scientifically effective suggestions to help improve wheat yields and resistance. The focus is to find practices that can greatly increase yields, improve fertilizer use efficiency, and be more environmentally friendly, thereby providing better protection for global food security. 2 Fertilizer Types and Their Roles in Wheat Growth 2.1 Nitrogen fertilizers: promoting vegetative growth and grain protein Nitrogen is a very important nutrient for wheat. It can make wheat grow faster and stronger, and it can also help to increase tillering, ultimately increasing yield and protein content in grains. The results of many field trials are similar. People have found that as long as more nitrogen is applied, wheat plant height, tillering number, dry matter accumulation and grain yield will be significantly improved, especially when the nitrogen application rate is appropriate (Arzu et al., 2024). Nitrogen can also increase the protein content in grains. Therefore, making good
