ABSTRACT
<p><b>OBJECTIVE</b>To study the mathematical model of optimum fertilizer application to Pinellia by field experiments.</p><p><b>METHOD</b>Three factors and 5 levels quadratic rotational combination design was applied to study the effects of N, P and K.</p><p><b>RESULT AND CONCLUSION</b>N, 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.</p>
