Abstract:A field experiment was conducted to study the effects of different nitrogen fertilizer application rates on the corn yield. The results show that a quadratic function parabola relationship exists between the application amount of nitrogen fer- tilizer and the corn yield. The best economic application amount of nitrogen fertilizer was 259.5 - 327.0 kg/hm2 and with this the corn yield was 8 358- 9 714 kg/hm2.
Keywords:Corn  Nitrogen fertilizer  Application amount
