Field experiment was conducted in China during 1998 to study the effects of N rates (0, 90, 180, 270, 360 and 450 kg/hm2) on yield, nitrate content of Chinese cabbage and N apparent losses. The results showed that, the optimum economic N rate (310 kg N hm-2), the nitrate content of plant and the N apparent losses in soil-plant system increased with increasing N rate. It was not possible to coordinate the yield effect, crop quality effect and environmental effect under experimental condition.
