Abstract
Wheat is one of the most important crops in the world, that it's low concentration of microelements is a serious problem in Iran. One of the reasons of this problem is the deficiency of the absorbable forms of these elements in soil. The field experiment was conducted in the Kurdistan University Research Station in 2013-2014. In this research the effects of zinc and copper foliar application were investigated on some morphological traits, quality and quantity of grain yield of wheat cultivars in Kurdistan region. Experimental design was randomized complete block design with factorial arrangement of treatments with three replications in dryland condition. Experimental factors were four wheat cultivars (sardari, rizhaw, karim and azar2) and four levels of foliar application (0, Zn, Cu, and Zn + Cu) in two stages including stem elongation and booting. The results showed that there were significantly difference between cultivars for plant height, spike number, seed number per spike, 1000 seed weight, grain yield, biological yield, grain protein, grain gluten and grain phosphorus concentration. The highest values of grain yield and biological yield belonged to sardary cultivar in comparison with evaluated cultivars. Foliar application levels including Zn, Cu and Zn+Cu significantly increased spike length, seed number per spike, grain yield, biological yield, grain zinc and copper concentration. It seems that zinc and copper foliar application has positive effect on wheat quantitative and qualitative characteristics.
