abstract
The most important mineral nutrient for plants is nitrogen, which is also a structural component of many proteins, enzymes, chlorophyll, rubisco, nucleic acids, and some hormones. Nitrogen also plays a major role in the vegetative growth of crops, making N fertilization a crucial agronomic management technique to increase crop productivity. Nano urea is a special kind of nitrogen that contains 4% nitrogen in a 500 ml bottle with particles that are 30–50 nm in size. For the precise and focused administration of nitrogen, it has become a revolutionary fertilizer. Nitrogen, a significant critical nutrient needed for improved crop growth and development, is included in nano urea (4% N). Finger millet (Eleusine coracana) is an essential cereal crop in the hilly regions of India, particularly in Uttarakhand, where it is widely cultivated due to its high nutritional value and resilience to drought. However, challenges such as poor soil fertility and nutrient deficiencies often limit its yield and overall performance. Recent advancements in nanotechnology, particularly the development of nano urea, have shown promising potential in improving the efficiency of nutrient uptake, growth, and productivity in various crops. This review aims to comprehensively analyze the effects of nano urea on the growth, yield, and performance of finger millet.
