Foliar nutrition of nano-fertilizers: A smart way to increase the growth and productivity of crops

Abstract

The objective of this literature was to know the importance of effects of foliar nano-fertilization on different crops compared to conventional nutrient sources and methods of application. Nanoscience and Nanotechnology research in agriculture and horticulture are still at an elementary stage but developing rapidly. Conventional bulk fertilizer or traditional fertilizers are not only expensive for the producer, but may be harmful to humans and the environment. This has led to the search for environmentally friendly fertilizers or smart fertilizer, mainly those with high nutrient-use efficiency, and nanotechnology is rising as a promising alternative. More recently, foliar feeding has been widely used and accepted as an essential part of crop production, especially on horticultural crops. Although not as widespread on agronomic crops, the benefits of foliar feeding have been well documented and increasing efforts have been made to achieve consistent responses.
