Utilization of Crop Residues at the Farmer’s Level in Rajasthan
- Essential Usage for Livestock and Fertilizer Preparation
- Crop residues from Bajra, Gram, Guar seed, Groundnut, Jowar, Maize, Moth, and Urad are extensively used as cattle feed.
- Portions of residues from Cotton, Bajra, Gram, Guar seed, Groundnut, Jowar, Maize, Moth, and Urad are also utilized in the preparation of compost manure.
- Fuel Usage for Domestic Needs
Cotton residue is commonly used as fuel for household cooking. - Field Preparation through Residue Burning
Residues of Garlic and stalks from Cotton, Rapeseed & Mustard, Rice, and Wheat are often burned in open fields to prepare the land for the next sowing cycle. - Commercial Applications
Farmers earn additional revenue by selling crop residues to briquetting or biomass plants, contributing to sustainable economic practices.
