To study the integrative effects of foliar and soil application of zinc and iron on wheat, a field experiment was conducted in spilt spilt plots of a randomized blocks design manner with three replications at shavoor station during 2002-2004, three levels of iron foliar (0,5,10 per thousand) as main plots, three levels of zinc foliar (0,3,6 per thousand) as sub plots and four levels of zinc soil application (O,300/0Iess than soil testing, soil testing, 30% more than soil testing) to sub sub plots were applied. All foliar treatments uesd in two times: in first stem elongation and first flowering. Soil application treatments were used in before planting. The results indicated that all treatments were no significant on wheat yield but increase in yield was observed. Zinc foliar application on wheat fortification was significant at 5% level but iron foliar application and zinc soil application were no significant on fortification. Investigation intregative between tretments showed that iron with zinc foliar application were significant on harvest index at 5% level and iron foliar with zinc soil application were significant on number of grains in spikelet at 5% level. Zinc soil application with zinc foliar application was significant on number of grains in spikelet and thousand-garin weight at 5% level. Intregative between tretments Zinc soil application with zinc foliar application were significant on seed elements at 5% level. The results showed that iron foliar, zinc foliar and soil application should be based on soil conditions. Finally zinc soil application treatment (soil testing) and foliar application with zinc (3 per thousand) or iron (5 per thousand) in first stem elongation stage was recommended.
