Abstract

A field experiment was carried out in Ningxia Lingwu farmland to study the effect of potassium fertilizer on sunflower yield.The results showed that compared to CK treatment application fertilizer can significantly increase sunflower yield,N,P treatment and N,P,K treatment can decrease sunflower rate of empty husks.N,P treatment and N,P,K treatment sunflower yield were increased 37.2% and 73.0% compared to CK treatment,respectively.Only the balance supply of N,P and K fertilizer can make the sunflower yield,quality and benefit best.
