Agriculture plays a pivotal role in economic development of every country. However, India after green revolution has achieved a great success in reducing hunger and bringing an overall rural prosperity; India has emerged as a role model for many developing countries. This fast development has some devastating effects. One of them is climate change due to which the world is often facing different types of natural calamities to introduce the term sustainable development. Sustainable agriculture in simplest terms enables us to produce healthy food without compromising future generations ability to do the same. Sustainable Agriculture includes a number of factors like proper use of resources, enhancing the environmental quality, providing quality food and fiber and finally enhancing the quality of the society as a whole. To achieve this goal many innovative technologies have been introduced which may be used safely by considering the issues of climate change. Seed, the most important part of the plant and easy to handle has attracted the plant scientists for various types of study and recently a technology, completely physiological in nature has been developed, named as seed priming technology. This has many fold impacts like mitigation of stress via improving tolerance mechanisms in plants, reduction in pollution etc consequently soil, water and atmosphere will be protected up to some extent beside increasing productivity of various crops. Further it is well known that essential nutrients may limit the growth of many crops but among them nitrogen is the most important nutrient, being the constituent of many cell organelles, enzymes and hormones. Nitrogen in form of nitrate is taken up by the plants except legumes and rice. Nitrate in its various levels has a number of roles in modulating the plant processes. The salts containing nitrate have been also introduced in the form of seed priming treatment for various crops. This review is the compilation of the above mentioned factors at a place to present their interactions.
