The optimal two-factor saturated D design was used to investigate effects of fertilization level(the fixed level of N∶P_2O_5∶K_2O=2∶1∶4) and planting density on Yield of Qianyu,a new potato variety.The results showed that the yield of 1900 to 2250kg/667m2 in the middle soil fertility could be obtained under fertilization level of 13.96 to 16.98kg/667m2 and density of 3574 to 4200 plants/667m2and the yield of more than 2 250kg/667m2 could be obtained under fertilization level of 14.98 to 16.57kg/667m2 and density of 4200 to 4884plants/667m2.
