A pot experiment was designed under drought stress condition to study the effect of different starter nitrogen fertilizer on fluorescence parameters in the leaves of relay strip intercropping soybean at branching stage. The Fo, Fv/Fm, PS, qP, NPQ and ETR were measured or calculated. The results showed drought stress significantly increased Fo and NPQ, reduced Fv/Fm, PS, qP and ETR. Nitrogen application soybean plants had higher qP, PSII, NPQ and ETR, as compared to the zero nitrogen application soybean plants when under drought stress. This could be because drought did not have a serious effect on the nitrogen application soybean plants compared to zero nitrogen application soybean plants.
