Abiotic stresses spot lights the field crops at all growth phases and results in significant yield losses in important crops, endangering the safety of the world's food supply. Numerous physiological, biochemical, and molecular tactics have been examined by crop researchers to battle drought stress/water limiting stress, but in the current environment, these measures are meager. It is so claimed that plants can be primed by various organic and inorganic stimulants for exceptional toughness under stressful circumstances. In order to confer tolerance, novel seed priming techniques are promising field of research in stress biology and crop stress management. Seed priming is the process of carefully hydrating seeds with germination stimulants so that pre- germinative metabolic activity can continue while the radicle's emergence is halted. The terms "hydro-priming," "osmo-priming," "halo-priming," "solid matrix priming," "bio-priming," and "hormonal priming" refer to various priming techniques. It will speed up and synchronize germination, improve plant growth and stand establishment, raise stress tolerance, improve fertilizer and water use efficiency, and have superior weed suppression effects. This review paper covers the physiological and biochemical changes through several seed priming techniques, Nano-priming and its significance in sustainable agriculture.
