ABSTRACT
Agriculture is the elementary source of food and feed worldwide. The present scenario of agriculture sector faces many problems such as global population increment and many environmental ecological hazards due to excessive use of agrochemicals. Conventional farming practices have detrimental consequences such as stagnation in crop yield, ground water contamination, biodiversity loss, etc. Due to these problems the agriculture sector needs an alternate approach to mitigate these challenges, and nanotechnology-based agriculture is one of the solutions. Nano-agriculture has many advantages such as crop production and yield enhancement, protecting crops from pathogens and pests and smart monitoring of crops. Nano-agricultural products such as nanofertilizers, nanopesticides and nanoherbicides have higher efficacy than conventional agrochemicals due to their smart delivery system. Nano-biosensors are used for smart monitoring of crops in order to protect crops from any kind of stressed condition.
