**6. Conclusion**

Sustainable development depends on the conservation of natural resources and reliance on renewable resources for the future generation. Hunger reduction and food security for all is the major goal of SDG. The consumer consciousness for health and well being is the major driven force for organic movement. The chemicals applied in the paradigm of shift in agricultural activities in recent past have destroyed the food quality, soil fertility and the environment to a large extent. Organic farming is a solution to overcome all of these problems. The organic products are in high demand in both developed and developing nations. It was observed that organic farming is beneficial to the marginal farmers in rural economy and also helps in maintaining a clean environment. Organic fertilizers make organic farming more sustainable. Crop production, soil fertility is also enhanced due to application of organic fertilizers. The role of vermicompost as an organic fertilizer plays a crucial function in sustainable eco-friendly farming with abundant benefits including maintaining soil quality and nutrient supply to the crops in efficient way. Vermicompost application also accounts for pest control, enhanced microbial activity in soil and release of no emission to the atmosphere. Terrestrial weed biomass is seen to be a good resource for vermicompost production. This can be utilized in an efficient way instead of discarding it into waste stream. The proper management of terrestrial weed biomass through vermicomposting can resolve the demand for organic fertilizer globally.
