A four-year field experiment was conducted to understand the characters of nutrient accumulation and distribution in maize under different yield levels, so as to provide scientific guidance for effective utilization of mineral fertilizers, and eventually for high yield of spring maize. The grain yield, nutrient (nitrogen, phosphorous, potassium) accumulation and uptake efficiency were evaluated under different agronomic managements and nitrogen application treatments. The data showed that thefatcat:p4vq7wllvrgrdmy3dxdkpq6gta
