Role of nano-urea in optimizing nitrogen use efficiency, yield and quality of rice: A review

More than 20% of the rice used globally is produced in India. Fertilizer application is necessary to increase rice productivity. When hybrid rice was sprayed with nano-urea in addition to nitrogenous fertilizer (urea), better growth was noted. It is anticipated that applying nano-urea at active tillering stage will improve input efficiency and increase rice yield. Nitrogen particles on nanoscale reduce the need for conventional fertilizers by half or more while enhancing crop yield, soil health and nutrient quality of the produce. According to published research, using nano-urea led to a 25% reduction in nitrogen (urea) usage. The control of nitrogen can improve the quality of Basmati rice. Compared to regular urea, rice treated with nano-zeourea consistently had a better quality. Consequently, its application in agriculture seems like a viable strategy, which will encourage the conversion of outdated agricultural techniques into modernized systems, with a particular focus on the creation of environmentally sustainable and more effective methods.
