An investigation was conducted on the effects of vermicompost on seed germination and some quantitative and qualitative characteristics of tomato (Lycopersicun esculentum) transplants under greenhouse conditions. The main aim of this research was to study the influence of different levels of vermicompost on seed germination parameters and the growth of greenhouse tomato. The results indicated that there were significant differences between treatments. The highest seed germination rate was in 25% vermicompost. Tomato seedlings growing in 100% vermicompost had the lowest amount of chlorophyll, the lowest leaf diameter, lowest dry weight and were the shortest seedlings between all treatments. The application of 50% vermicompost increased the inter-node number, root dry weight and N content of tomato seedlings significantly compared to the control plants. Incorporation of 25% vermicompost increased significantly the shoot dry weight and leaf area of tomato seedlings compared to the control.
