Stady of iron and Zinc effect on function of three Kind of flint Corn( 704,770,7020) experimentally , on factorial base , has been done in the framework of completely random blocks in 4 resptition , at Sistan Dist ., in 2010. Three kind of flint corn ( v1= 704, v2= 770 , v3= 7020 ) were considered as figures factors and fertilizer factors , including (F1= Witness ,F2= Zinc sulphate , F3= iron sulphate , F4= iron sulphate + Zinc sulphate , as the second factors . Results demonstrate that fertilizer treatment have no significant effect on Wight of 100 seeds, function of seed , biologic function harvest index , and protein percentage . Result of variance isolation show that harvest index was different and difference of interaction between figures and fertilizer treatments on the harvest index was significant in 5%.
