Recently, mushroom farming has become a popular kind of self-employment for many unemployed people. It is past time that mushroom growers and consumers in India learned about the therapeutic and dietary benefits of both farmed and wild kinds of mushrooms. The majority of all mushrooms are white button mushrooms, accounting for around 73 percent of the market. Compost is necessary for cultivating white button mushrooms. The substrate in which the mushroom mycelium grows and eventually produces fruiting bodies is compost. The critical shift from vegetative growth to the reproductive stage occurs in the coating material, which is a nutritionally deficient medium is called casing layer. This layer plays a vital part in the formation of mushrooms. The most crucial process in mushroom cultivation is composting and casing, which has an impact on the crop's productivity, quality, and market value. Keywords: Mushroom cultivation; compost; casing; yield; medicinal value. Review Article
