2. Introduction Food and agriculture sectors - promising area - sustainability and economic growth of a country. With limited availability of land and water resources, growth in agriculture can be achieved only by increasing productivity through good agronomy and supporting it with an effective use of modern technology . Nanotechnology based sensing gained enormous momentum and provided broad spectrum application in food and agriculture sector Implementing nanotechnology - provided a new edge to the agrotechnology, improved irrigation and efficient delivery of agrochemicals like fertilizers, herbicides and pesticides, and enhanced the food production and processing, packaging and storage.

3. Cont … Major portion of the research in agricultural nanotechnology is in the area of degradation of harmful pesticides by converting them into harmless and useful components such as minerals and water. Nanosensor-usefull for in-field, on-line and real-time detection of pesticides, pathogens, toxic materials, proteins, antibiotics, odours creating bacteria, microbes, etc. in soil, air, water, food, plants and animals. Nanotechnology puts the impetus to revolutionize the area of diagnostics in health, medicine, food, environment, and agriculture sector, transitioning theoretical aspects into the practical output.

4. “An extremely small device capable of detecting and responding to physical stimuli with dimension in the order of one billion of a meter ” Physical stimuli : biological and chemical substances, displacement, motion, force, mass, acoustic, thermal and electromagnetic. It collects and measures data regarding some property of a phenomenon, object, or material. • Nanomaterials and nanosensors increase sensitivity and detection level to pico-, femto-, atto- and even zepto- scales (10 -12 -10 -21 ) – this facilitates helps in early detection.

11. Detect plant disease Physiological changes Soil temperature and Moisture precision farming Gas nanosensors

12. Disadvantage Understanding the relationship between nanoparticles and the environment forms an important area of research. There are several mechanisms by which nanoparticles are believed to affect the environment negatively. some nanoparticles are able to reduce the functioning of (and may even disrupt or kill) naturally occurring microbial  communities , as well as microbial communities that are employed in industrial processes (e.g., those that are used in sanitation processes, including  sewage treatment ).

13. Conclusion Nanosensors could play an important role in providing powerful analytical tools to the agricultural diagnosis sector, Rapid, low cost, high sensitivity and specificity measurements in field situations are required. A wide range of transducers is also available to engineer new Nanosensing devices. The promise shown by biosensor technology is very real, however there are some technological obstacles that need to be overcome.
