A field experiment was conducted to study the effects of nitrogen (N) forms on active iron,SPAD values of young leaves and pod yield in Yuanza 9102 and Zhuhua 1 peanut cultivars(main treatment),the experiment was laid out in a split plot experiment design with 100% ammonium N fertilizer,50% ammonium N fertilizer /50% nitrate N fertilizer and 100% nitrate N fertilizer,respectively(secondary treatment).The results showed that,the pod yield 50% NH+4 N/50% NO-3 N fertilizers treatment of both yuanza 9102 and Zhuhua 1 were the highest,but the yield of yuanza 9102 was significantly higher than Zhuhua 1.In flowering pegging stage and pod setting stage,with ammonium proportion increased,active iron content in yuanza 9102 leaves were decreased,while which of Zhuhua 1 were increased;SPAD values of new leaves were all increased.In summary,the pod yield of Yuan za 9102 peanut cultivar applied by 50% NO-3 N/50% NH+4 N fertilizers treatment was the highest.
