Abstract :
Using microelements is very important to increase quantitative and qualitative characters of wheat. In order to evaluate the effects of foliar application of elements such as zinc, iron and manganese on yield and yield components of bread wheat cultivars an experiment was conducted based on a Randomized Complete Block Design (RCBD) with three replications at Torbat-e-jam in 2015-2016. Factors were foliar application including iron, zinc, manganese, iron+zinc, iron+manganese, zinc+manganese, iron+zinc+manganese and control treatment. Foliar application was done using micronutrients chelates to the amount of one in thousand at shooting and flowering stages. The results showed that foliar application had significant effect on plant height, spike length, the number of grains per spike, grain yield and harvest index. Foliar application increased plant height significantly. The highest plant height obtained from application of iron+manganese, iron+zinc+manganese and zinc+manganese. The maximum length of the spike was seen in foliar application of iron, zinc, iron+manganese which had not significant difference with control treatment. The number of grains per spike in zinc and zinc+iron+manganese treatments were higher than control. Generally it seems that none of foliar application treatments could increase the grain yield compared to control treatment.
