| Abstract: | The 416 D saturated optimum regressive design was adopted to evaluate the effect of mixing application of N, P, K and Si fertilizers on the dry matter and seedling quality of Cathay poplar on a sandy loam aluvium. The results of regressive and frequency analyses showed that the optimum fertilization pattern was N: 16. 64 g/m2, P2O5: 3. 24 g/m2, K2O:17. 0 g/m2, and zeolite: 31.61 g/m2. |

| Keywords: | Cathay poplar yield optimum fertilization quadratic regressive equation frequency analysis |
