Abstract

In order to study the effect of interaction of micro and macro elements on soil chemical properties, grain yield and yield components in barley, an experiment was conducted as split plot design on randomized complete block design with three replications in research field of Zabol University, 2008. Different proportions of manure and chemical fertilizer treatment were composed of: 100% manure (F₁), 100% chemical fertilizer (F₂), 50% manure + 50% chemical fertilizer (F₃) and control as the main plot; and use of micro nutrient elements were composed of: iron sulfate (N₁), zinc sulfate (N₂), magnesium sulfate (N₃) and control (N₄) as sub plot in this experiment. Results of this research showed that fertilizer proportions and nutrition elements, with the exception of grain number in ear and germination percentage had the significant effect on yield and yield components, and other germination characteristics of barley. The highest amounts of grain yield, 1000 grain weight and biological yield was obtained in F₂N₃ (100% fertilizer and FeSO₄), and the highest amount of forage yield was found in F₃N₁ (50% manure + 50% fertilizer and FeSO₄). Among nutrition elements, use of FeSO₄ had more influence on yield and yield components of barley.

Key words: Barley, fertilizer, germination, manure, yield.
