Effect of different microelement treatment on wheat (triticum aestivum) growth and yield

Abstract: In order to study the effects of foliar micronutrient application on growth and yield of wheat, a field experimental was carried out in a randomized com plete block design with four replications at agricultural research station of Delgan city, Sistan Province, Iran during 2010 growing season. Different treatments of micronutrient foliar including, F1=Fe 2.5 lit/1000 form Iron sulphate, F2= Zn 2.5 lit/1000 form Zinc sulphate, F3= Mn 2.5 lit/1000 form Mn sulphate, F4= Fe+Mn 1.5 lit/1000, F5= Zn+Mn 1.5 lit/1000, F6= Fe+Zn 1.5 lit/1000, F7= Fe+Zn+Mn 1lit/1000, F8= Fe 4 lit/1000 form Iron sulphate and F9= control were applied. The results showed that micronutrient application significantly affected plant height, number of spike per plant, number of grain per spike, 1000-grain weight, grain yield, biological yield and harvest index. Application of Mn+Fe had the highest positive effect on yield components and grain yield. The combination of Zn+ Fe+Mn and control gave the lowest values of most studied traits. It could be concluded that micronutrient application had positive effect on wheat growth and yield
