Abstract: To study effects of different types of fertilization with elements of Iron, Zinc, Manganese and Cupper on quality and quantity performance of barley (Hordeum Vulgare L.) a pot style factorial experiment based on randomized block design with three replications was conducted in research greenhouse of Pardis-Saveh agricultural training center in 2010. Experimental factors were included in three levels of soil fertilization with Fe, Zn, Mn and Cu (Copper sulfate and Manganese sulfate 0, 2.5 and 5 mg/kg soil, and Iron sulfate and Zinc sulfate 0, 5 and 10 mg/kg soil) and two levels of solution spraying with these four elements (solutions of 0 and 0.002 Fe, Cu, Mn and Zn Chelate EDTA). None of the treatments used, showed any significant effect on grain protein percentage and number of tiller. Soil fertilization with Fe, Mn and Cu increased yield components significantly while soil fertilizing with Zn not only increased yield components significantly but also increased number of fertile tillers at level of 1%. Result analysis showed that application of Fe in form of solution spray increased grain yield and 1000 grain weight compared to the control while solution spraying of Zn increased grain yield significantly. Results derived from this experiment suggests that in order to increase yield components, number of tillers and number of fertile tillers in barley plant it is better to use soil fertilizing with Fe, Zn, Cu and Mn while for raising of grain protein percentage and improvement of grain yield qualitatively both method of soil fertilizing and solution spraying are recommended.
