%X The effects of different amounts and kinds of nitrogen fertilizer on rice yield and its nitrogen uptake and utilization were studied on a main paddy soil (Wushan soil) of Taihu area. The results indicated that the optimal amount of nitrogen fertilizer was about 180 kg N.hm-2 for rice production. Applying ammonium sulfate was better than applying urea for increasing rice yield. The efficiency of nitrogen fertilizer in this experiment was about 41.8-48.5%, and its loss was 22.8-38.1%.
