| Abstract: | The models of fertilization on peanut in Liaoning was investigated under the condition of the yield using 3414design.it could obtain NPK three factor gradual regression,Y=2693.10+360.87N+141.53P+104.95K-9.90NP +12.59NK+31.03PK-62.52N2-31.18P2-30.88K2 and N,P and K fertilizer effect function Y=3065.64 + 576.51N-94.86 N2,Y=3395.34+346.48P-51.02P2 and Y=3099.21+366.55K-43.82K2.The gained maximum yield was 3960 kg hm-2 under the N amount of 51 kg hm-2,P2O5 of 56 kg hm-2 and K2O of 70 kg hm-2.The findings were u... |
