Effect of Foliar Application of Nano Urea on Growth and Yield of Maize (Zea mays L.): A Review

maize requires large amounts of nutrients for appropriate growth, production and yield, it is regarded as a crop that is nutrient-exhaustive. The nutrient requirements of the maize crop can be maintained with the use of effective nutrient management techniques. Nanotechnology is gradually making its way from the experimental to the useful realms, like the development of slow-release fertilizers, conditional release of pesticides and herbicides, on the basis of nanotechnology has become critically important for promoting the development of environment friendly and sustainable agriculture. Traditional fertilisation techniques may undergo a revolution thanks to the inherent features of nanoparticles, which enable improved nutrient absorption, precision distribution and greater bioavailability. The results, as evidenced by multiple studies, indicate significant improvements in growth parameters, seed production, and overall plant health.
