Effect of enriched vermicompost manure in improve of iron and zinc deficiencies and quality characteristics of peach trees

In order to determine the effect of compost and vermicompost enriched with iron and zinc on iron and zinc nutritional status of peach trees a randomized complete block design with three replications carried in agro-industry and livestock cooperation of Moghan in Parsabad town of Ardabil province.

The results showed that the concentration of iron, zinc and chlorophyll of peach leaves in various treatments was statistically different (p < 0.05). The maximum concentrations of iron, zinc and chlorophyll of leaves, were observed in treatments that vermicompost enriched with iron, zinc and sulfur.
