Abstract: [Objectives] To study the effects of different proportions of controlled release urea and ordinary urea on peanut yield. [Methods] A total of 5 treatments were set up according to different proportions of controlled release urea and ordinary urea, randomly arranged in blocks and repeated 3 times. [Results] The test results of field districts showed that different proportions of controlled release urea and conventional urea had different effects on peanut yield. On the basis of applying 50 kg/666.7 m2 of calcium superphosphate and 17 kg/666.7 m2 of potassium sulfate, 13.34 kg/666.7 m2 of pure nitrogen was applied. The optimal ratio of controlled release urea to ordinary urea was 75：25, followed by 50：50. The output was 379.83 and 371.83 kg/666.7 m2, separately increased by 6.74% and 4.50% compared to the application of ordinary urea. [Conclusions] The combined application of controlled release urea and ordinary urea in peanuts can significantly increase peanut yield compared to just applying ordinary urea.
