ABSTRACT

Oyster mushroom is basically an . Oyster mushroom name originated from Latin [pleurotus- sideways, oyster- shape of the cap] which is namely refers to the shape of the fruiting body and the sideway growth of the stem with respect of the cap. Edible Mushroom belongs to the wide range of Division – and Kingdom– Fungi. Oyster Mushroom is commonly known as “Dhingri” in India. It may also grow on

rot and organic matter. At present time it is commercially cultivated all over the world but firstly cultivated at Germany during World War .Even now a day it is used as industrially for purpose. Oyster mushroom is commonly sought wild mushroom, it is K e yw or ds lingo cellulose growing in nature on living or dead. Recognized as peculiar morphology with eccentric short stem or . Cultivation technology of oyster mushroom Fruiting body, is very simple and cheap. Theoretically each crops takes 45 days under controlled Decaying, conditions and hence there can be 8 crops per year. It is the 3rd largest cultivated mushroom Myco remediation, Lingo cellulose, in the World. China alone contributes 88% of the total world population. Oyster 0 Peculiar , mushroom can grow at moderate temperature ranging from 20 to 30 C and humidity 55- Eccentric, Dhingri 70% for a period of 6 to 8 months in a year. It can also be cultivated in summer months by providing the extra humidity required for its growth in hilly areas above 900m. Oyster mushroom is economically profitable crop with high demand and supply pattern and exports. Its management is simple and easy to maintain on a closed low ventilation room. Oyster Mushroom can be used in Women Empowerment, the small village‟s women can make money by cultivating oyster mushroom at their home. Major problem we suffer in oyster mushroom is the nutrient requirement and the Common fungal and bacterial disease are Moulds, Green moulds, Ink caps, Brown spot, Yellow blotch, Bacterial rot.

Introduction organic matter. The fruiting bodies of this mushroom are distinctly shell or spatula Oyster Mushroom () shaped with different shades of white, belonging to class Basidiomycetes and cream, grey, yellow, pink, light brown Family Agaricaceae is popularly known as depending upon the species . The Oyster „dhingri‟ in India and grows naturally in the mushroom is one of the more regularly temperate and tropical forests on dead and looked for wild , however it can decaying wooden logs or sometimes on likewise be developed on straw and other dying trunks of deciduous or coniferous media. It has the clashing fragrance of woods [nhb.gov.in] .

Name - Both the Latin and regular Scientific classification names allude to the shape of the fruiting body. The Latin pleurotus (sideways) KINGDOM Fungi alludes to the sideways development of the DIISION Basidiomycota stem as for the cap, while the Latin ostreatus CLASS (and the English common name, oyster) ORDER refers to the shape of the cap which FAMILY resembles the bivalve of the same name.
