Abstract:
OBJECTIVETo study the mathematical model of optimum fertilizer application to Pinellia by field experiments.
METHODThree factors and 5 levels quadratic rotational combination design was applied to study the effects of N, P and K.
RESULT AND CONCLUSIONN, P and K combination application can achieve the maximum yield of 29,921.4 kg x hm(-2), the amount of N, P2O5, K2O were 413.79, 224.79, 164.01 kg x hm(-2), respectively. The effects of the 3 factors were in following orders: P > N > K.
