The experiment was carried out in two fields where available phosphorus level in 0～20 cm soil layer were 15.94 mg/kg and 30.44 mg/kg.The results showed as follows.For field M-P,the kernel yield significantly increased with phosphorus applied,but phosphorus applied had not significant effect on the kernel yield in field H-P.For utilization ratio of phosphorus fertilizer,the treatments P_2 were both highest in both experimental fields,and it was better in field M-P than that of field H-P.Also the content of g...
