The first experiment was performed to evaluate the effect of vermicompost extract (20, 40, 60, 80, 100%) on seed germination and seedling growth of Plantago psyllium. In second experiment, the effect of solid vermicompost with 4 levels (0, 25, 50, 75) on the emergence and subsequent growth of plantlets was investigated. The 20 and 40% increased germination capacity, germination index, and length of root, shoot, vigor index and decreased mean germination time and T50. In second experiment 25% increased emergence energy, emergence rate, emergence index and emergence cofficiennt  and decreased mean emergence time. 25% and 50% treatments increased the diameter, length, dry and fresh weight of root and aerial parts and length and width of leaves, and a, b, total chlorophyll and carotenoid in 3 old months's plant. But high concentrations were decreased these parameters. Thus, the effect of vermicompost on seed germination and subsequent growth of plantlets is dependent on concentration.
