ABSTRACT
The indefinite increase in the world population is raising a concern in the agriculture sector. The existing resources will be amenable to feed the increasing population in the presence of numerous environmental stresses: climate change, biotic and abiotic stress. Intensive farming, usage of chemical fertilizers and human urbanization directly conferring anthropogenic activities affect the soil fertility, which leads to deterioration in crop productivity and delimits the soil nutrition status. This situation can be overcome by using a cost-effective and an eco-friendly approach: nanotechnology can be a great step forward in ensuring a persistent, safe and sustainable agriculture. Nanoparticles’ significant feature of having size in the nanometre scale makes it a valuable tool for gaining access to provide direct nutrition in plants as nanofertilizers which was earlier lost via conventional method of chemical fertilization. At the present era, nanotechnology is a remarkable tool for plant disease management and monitoring plant health for the maintenance of food security as future prospective.
