Field studies were conducted in China to determine the effects of nitrogen (N) fertilizer rate and ratio of basal and topdressing fertilizer applications on wheat grain yield, fertilizer use efficiency, N fertilizer loss and residual N in 0-200 cm soil layers under high yield conditions. The appropriate N fertilizer rate and ratio of basal and topdressing were chosen for obtaining profitable yield, high N fertilizer use efficiency (NFUE) and reduction of possible environmental pollution.
