Abstract—Agriculture is a crucial sector for economic development of a country, as it generates employment, reduces poverty as well as provide food security for the people of a country. But as the population grows at an accelerated rate, demand for food production is also increased. In this regard, polymer researchers have developed a new kind of polymeric material that is hydrogel, to use as an alternative technique for conventional agricultural methods. Hydrogel can be used as a soil conditioner and controlled release system in agriculture which release water and fertilizer gradually to the plant for a long period. Herein, we reviewed the application of polymeric hydrogel in agricultural application and illustrating how they are practiced for sustainable development.
