Abstract

In order to study the effect of the interaction of manure and chemical fertilizer on yield and yield component of 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 treatments were composed of 100% manure (F₁), 100% chemical fertilizer (F₂), 50% manure + 50% chemical fertilizer (F₃) and control (F₄) as the main plot. Use of micro nutrient elements were composed of Iron Sulfate (N₁), Zinc Sulfate (N₂), Manganese Sulfate (N₃) and control (N₄) as sub plot in this experiment. Results showed that the effect of different proportions of manure and chemical fertilizer treatment on grain yield and yield components properties with the exception of grain number/ear, were significant. Nutrient treatments had a significant effect on grain yield and yield components in barley and among this nutrient use of Fe (N₁) had maximum effect on grain component of barley.

Key words: Barley (Hordeum vulgare), chemical fertilizer, manure, yield.
