Background &Objeftive: Vermicompost application plays an important role in agriculture. Crop plants can be sensitive to negative effects of vermicompost at early stages of development. The aim of the present study was to test the effects of different vermicomposts on seed germination of lepidiumsativum species. Materials & Methods: In the current work, the effects of different vermicomposts’ extracts, which were produced from cow manure, fruit waste, paper, sawdust and leaves, on s germination and early development of lepidiumsativum were investigated in various volumetric percentages (0%, 15%, 30% and 45%). For data analysis, Statistical Package for Social Science (SPSS) program and ANOVA test were used. Results: The results showed that different volumetric percentages were effective on lepidiumsativum growth. Average growth in volumetric percentage of 30% was less than 15 and 45%. In the way that presence differences was significant. Volumetric percentage of 15% was in appropriate level for plant growth and seed germination. Conclusion: It can be concluded that the use of vermicompost extracts can have an effective role in production efficiency increase of lepidiumsativum.

Introduction: Daily excreted large amounts of waste from human communities in different ways. A significant portion of this waste consists of organic material. The recycling of these materials and using them in different ways prevent the damage caused to the environment and conserve resources and energy is human attention. One of the appropriate methods of disposal of these wastes, production of organic fertilizer, vermicompost is. Objectives & ( hypothesis OR questions): Given that the municipality Ghochan, rotted cow manure and dried leaves of the trees used to produce vermicompost In this study the vermicompost production of cow manure, fruit waste, paper, sawdust and leaves (as carbon source) and germination index vermicompost is examined To finally be able to obtain the best additive to produce vermicompost. Materials & Methods: 5 treatments that are used to carry out the plan include: cow manure- Fruit lesions- Sawdust- leaf- Paper- Composition of the waste. Results: Used waste includes waste sawdust, fruit, paper, leaf and composition of the waste is suitable for vermicomposting is Eisenia fetida earthworms and proper nutrition. Waste paper to produce vermicompost alone is not suitable and it is better to prepare vermicompost should be used in combination with other organic wastes.. Conclusion: Changes of ash and carbon and C / N ratio indicates the fact that virtually After 70 days, the bedding materials are firmly established.
