Button Mushroom (Agaricus spp.) is the most popular mushroom variety grown and consumed the world over. In India, its production earlier was limited to the winter season, but with technology development, these are produced almost throughout the year in small, medium and large farms, adopting different levels of technology. The species being grown in most farms is the white button mushroom (Agaricus bisporus) belonging to Class Basidiomycetes and Family Agaricaceae.
Large scale white button mushroom production is centred in Europe (mainly western part), North America (USA, Canada) and S.E. Asia (China, Korea, Indonesia, Taiwan and India). The national annual production of mushrooms is estimated to be around 50,000 tonnes with 85 percent of this production being of button mushrooms.
White button mushrooms are grown all over the world and account for 35-45 % of the total mushroom production. In India, large units with production capacities between 2000 – 3000 tonnes / annum, have been set up mainly as export oriented units in the southern, western and northern regions. A large number of small units without climatic control equipment exist throughout India and function during the autumn and winter months only.
A big gap exists between the demand and supply position of white button mushrooms in the United States and European market. India exports the highest quantity of the mushroom produced in the country to USA. Netherlands and China account for 60% of the export of mushrooms. Germany is the largest importer and France and UK are large producers as well as consumers.
n India, button mushrooms are grown seasonally and in environment controlled cropping houses. White button mushroom requires 20-280 C for vegetative growth (spawn run) and 12-180 C for reproductive growth. Besides that it requires relative humidity of 80-90% and enough ventilation during cropping. Seasonally, it is grown during the winter months in the north-west plains of India and for 8-10 months in a year on the hills. However, with the advent of modern cultivation technology it is now possible to cultivate this mushroom anywhere in India.The growers can take on an average 3-4 crops of white button mushrooms in a year depending upon the type and varieties cultivated. Factors affecting the yield of the crop both in terms of quality and quantity are incidence of pests/pathogens and non-availability of pure quality of spawn.
Ooty 1 and Ooty (BM) 2 (released in 2002) are the two strains of button mushrooms released for commercial cultivation by the scientists of Horticulture Research Station of the Tamil Nadu Agricultural University at Vijayanagaram, Ooty. The strains which are mostly cultivated in India are S-11, TM-79 and Horst H3..
