| Abstract: | The response function of fertilization in N, P and K were obtained by fertilizer experiment for "3414" of N, P and K in Brassica oleracea L. var. italica. The unitary quadric equations were as following respectively. Y=891 45.02P- 0.884P2 (R=0.858), Y=1 118 37.4P-1.229P2 (R=0.568), Y=1 060 16.37K-0.113K2 (R=0.752). The theory optimum rate of application of N, P2O5 and K2O were 385.5 kg/hm2, 151.5 kg/hm2 and 274.5 kg/hm2 respectively. |
