Abstract: Effects of decreasing coated urea application on potato's yield and quality were studied by field experiments.The results indicated that decreasing coated urea appropriately could increase potato's yield compared with traditional fertilizer,chlorophyll content of leaves and quality.The best treatment in potato's yield was 80% peucine-sulfur coated urea(80% PSCU) and it could increased yield 13.14%.100% AU and 80% AU were better in chlorophyll content of potato's leaves,and different between the two treatments and other coated urea treatment was not significant.80% PSCU was the best of all treatments in potato's quality,potato's starch content was 16.85% and was the highest,potato's nitrite content was 20.89 mg/kg and was the least.

Key words: Coated urea, Potato, Fertilizer decrement, Yield, Quality
