Abstract:	*Aims* The aim of this study was to explore the response of photosynthetic carbon assimilation and photosynthetic nitrogen (N) use efficiency (PNUE) of maize to intercropping system of maize and potato under different N addition, which has a great significance for the N regulation and N fertilizer management for the increase in intercropping yield.

Keywords:	intercropping nitrogen level leaf nitrogen content photosynthetic rate photosynthetic nitrogen use efficiency
