Abstract：In order to improve the nitrogen apparent efficiency and the growth of peanut, the effects of combined application of coated urea and common urea on the main agronomic characters,yield,nitrogen apparent efficiency were studied. The results showed that the combined application of common urea and coated urea could effectively improve hundred-fruit weight and other major agronomic traits,and increased the yield and nitrogen apparent efficiency,of which the treatment with 30% common urea combined with 70% coated urea had the best effect,the yield of the above treatment reached 7 622. 2 kg/ha,increased by 37. 75% compared with control without nitrogen fertilizer, the nitrogen apparent efficiency of the above treatment reached 34. 6%,the treatment with 50% common urea combined with 50% coated urea was the second.
