Abstract

Green revolution increases food production to satisfy consumption rate by adopting improved varieties, high fertiliser dose and irrigation etc. Crop production increases the food-grain as well as biological yield. Rice wheat and sugarcane contribute in high residue generation due to more crop residue generation on and creates difficulty in off-farm management. Due to their high C:N ratio mineralisation process slows down and sowing of crop on standing residue will affect germination and plant stand. Since farmers need quick land preparation for the next crop sowing, they will burn the crop residue, which creates environmental pollution, health hazards, loss of organic matter and loss of essential plant nutrients. Hence collection of crop residue and utilisation in same farm by production of compost is best alternative and eco-friendly method of residue management. Among different types of composting, Vermicompost is best method as it is an eco-biotechnological process to manage agricul

Conclusion

Crop residue burning is major constraint in residue management, it will have effect on nutrient status in soil and plants, pollutes environment, health hazards and also increases soil temperature which will effect on soil beneficial microbial populations. Rice-wheat cropping system dominates in residue generation as compared to other cropping systems in India. Residue removal and transporting to other place for different purposes and residue incorporation needs heavy and costly machineries and is not economical to small and marginal farmers. Hence, the residue can be collected and utilised in farm by producing Vermicompost. It is cost effective, little skill requiring, easily manageable for agricultural, domestic and biodegradable wastes. It supplies high nutrient content mainly NPK, micronutrients and growth promoters, minerals etc. Compared to other compost (FYM, bacterial compost, kitchen compost), it can be applied directly on standing crop. After application of the compost, it rea
