Exploring the Integration of Nano Urea in Linseed Cultivation: A Comprehensive Agricultural Review

Agriculture in the 21st century faces the challenge of increasing food production to meet the demands of a growing population, while addressing soil nutrient depletion, reduced NUE, and the environmental impacts of conventional fertilizers. Nitrogen, a macronutrient, is often lost through leaching and volatilization when applied in traditional form. Nanotechnologies, offer a promising solution by enhancing nitrogen delivery and uptake efficiency in crops. This review examines the global agricultural context, the role of nitrogen in crop productivity and plant development. Recent studies, especially in linseed cultivation, have demonstrated that integrating nano urea with reduced doses of conventional nitrogen significantly improves seed yield, nutrient uptake, and economic returns. However, the widespread adoption of nano fertilizers requires further investigation into long-term soil impacts, residue effects on oil quality, and integration with precision agriculture. Overall, nano urea stands as a pivotal innovation for sustainable agriculture, offering a scalable strategy to enhance productivity while preserving environmental integrity in a resource-constrained world.
