Abstract

To study the effect of different vermicomposts, enriched with zinc and iron, on dry weight and seed germination of corn, a pot experiment was conducted in a complete block design with ten treatments and three replications. Nine different vermicomposts including vermicomposted rice hull + chicken manure, rice hull+cow manure, and cow manure and zinc and iron enriched forms of them were used. The nitrogen content of all vermicomposts treatments and the control were equalized by addition of urea. The results of analysis of variance showed that there were significant differences among the treatments with respect to biomass dry weight of corn. The highest dry weight for corn biomass was measured in the treatment having rice hull+chicken manure vermicompost enriched with zinc. In contrast, the lowest dry weight for corn biomass was observed in the control. Different vermoicomposts had significant effects on seed germination of corn. Application of vermicomposts improved seed germination of corn and all treatments had higher seed germination percentages than that of the control. The highest seed germination percentage was observed in the treatment with vermicomposted rice hull + cow manure enriched with iron.
