Pot experiments were carried out to compare different effects of sulfur-coated urea(SCU) with urea on growth and nitrogen use efficiency(NUE) of rice.Results obtained were as follows:(1) SCU had significantly positive effects on growth of rice at tillering stage
but with smaller increment compared to urea.At harvest stage
on condition of applying the same rates of fertilizer and N dosage
the grain yield of rice applied with SCU were 35.7% and 19.3% higher than those with urea
respectively.At the same nitrogen usage
treatment with SCU has higher thousand-grain weight while less effective spike number than those of urea;(2) NUE and partial factor productivity for applied N(PFP) of rice fed with SCU were higher than those with urea.At the same fertilizer dosage
NUE of SCU treatments were 47.35% to 57.48%
which were 12.5% higher than urea treatments on the average.PFP on SCU treated rice were increased by 10% than urea.At the same N dosage
NUE of SCU application treatments were 17.12% higher than those of urea
