To address the issues of unreasonable chemical fertilizer management, low fertilizer use efficiency, and escalating environmental risks in the maize production areas of Inner Mongolia, field plot experiments were conducted in two typical production areas, namely the black soil region of Northeast China and the Tumochuan Plain. Six treatments were established: no nitrogen control (CK), 100% chemical fertilizer (M0), and organic fertilizer replacing 25% (M25), 50% (M50), 75% (M75), and 100% (M100) of chemical nitrogen, to clarify the effects of different substitution ratios on maize yield, dry matter accumulation, fertilizer use efficiency, and nitrogen (N), phosphorus (P), and potassium (K) nutrient uptake. The results showed that the M25 treatment significantly increased maize yield, with an increase of 4.69%-36.80% compared with other treatments. The M0 treatment exhibited the highest dry matter accumulation of various organs during the early growth stages of maize; however, the M25 treatment showed a distinct advantage from the large bell-mouth stage to maturity. The M25 treatment promoted the uptake of N, P, and K nutrients and enhanced their utilization efficiency; the partial productivity of fertilizer in M25 was 2.77%-50.51% higher than those of other treatments. In conclusion, the response of maize to organic fertilizer substitution in the Tumochuan Plain was superior to that in the Black Soil Region of Northeast China, and replacing 25% of chemical nitrogen with organic fertilizer can achieve a synergistic improvement in maize yield and fertilizer use efficiency.
