The effects of two different sulfur coated urea fertilizers (SCU1, SCU2) on green pepper’s yield, quality and nitrogen use efficiency were studied under the conditions of equal or 30%-decreased nitrogen inputs by field experiment. The results showed that the equal and 30%-decreased application of SCU1 and SCU2 fertilizers increased significantly the yield from 2.8% to 16.6% and Vc content from 3.5% to 10.2% compared with the urea treatment, and SCU2 increased the yield higher than SCU1 but SCU1 increased Vc content higher than SCU2, probably because of their differences in the thickness of coat. There was no significant difference in N recovery efficiency and partial productivity between the urea and the equal N sulfur coated urea, but the application of equal N SCU2 increased significantly N agronomic efficiency compared with the urea treatment and the equal N SCU1. N recovery efficiency, N agronomic efficiency and partial productivity of 30%-decreased N SCU1 and SCU2 were significantly higher than those of the urea and equal N SCU1 and SCU2. No significantly difference in the yields of next crop was observed between the urea and sulfur coated urea, but the yields of next crop under the urea treatment and sulfur coated urea were significantly higher than that without fertilizer application. In conclusion, sulfur coated urea increased the yield and Vc content of green pepper but not N recovery efficiency, and SCU1 was better than SCU2 in increasing Vc content while SCU2 better than SCU1 in increasing the yield.
