How To Start a Button Mushroom Farming Business

    Mushrooms are often referred to as “nature’s hidden treasure.” It has enchanted the culinary world with its unique flavours and textures. Among these culinary delights, the button mushroom (Agaricus bisporus) stands as one of the most widely consumed and appreciated varieties globally. These little fungi also hold the potential for a thriving business venture. Here in this article, we provide you with all the details needed to start a button mushroom farming business.

    Mushroom production is a growing business globally. As the demand has been increasing for the last few years farmers are getting inspiring profits from this product. In addition, mushroom cultivation is a matter of practice and technical knowledge with a high value of return in a short time.

    Mushroom production has some key raw materials to get good yields. However, the major essential three raw materials are spawn, compost, and casing soil. And you can start this type of mushroom farming on a small-scale basis. Even you can start from your backyard or home.

    Here are the 10 Steps of Button Mushroom Farming

    1. Market Research and Business Plan

    Begin with thorough market research to understand the demand for button mushrooms in your target area.
    Develop a detailed business plan that outlines your goals, budget, and strategy for the mushroom farm.

    2. Location and Infrastructure

    Choose an appropriate location for your mushroom farm, considering factors like climate, accessibility, and proximity to markets. Set up the necessary infrastructure, including growing houses or sheds, temperature and humidity control systems, and storage facilities.

    3. Regulatory Compliance

    Check the local and national regulations related to mushroom farming. Ensure you have the necessary permits and licenses.

    4. Spawn and Substrate

    Source high-quality mushroom spawn (seeds) and substrate (the material on which mushrooms grow). Common substrates include compost, straw, and gypsum. Maintain a sterile environment to prevent contamination.

    5. Growing Environment

    Create a controlled environment with the right temperature (around 25-28°C), humidity (85-95%), and lighting conditions (limited light exposure). Mushroom-growing houses should be dark and well-ventilated.

    6. Spawn Inoculation

    Inoculate the substrate with mushroom spawn. This involves mixing the spawn with the substrate and packing it into trays or bags. Allow mycelium (the vegetative part of the fungus) to colonize the substrate.

    There are three different types of spawning you can avail of.

    a) Spot Spawning

    You can plant the lumps of spawn in 5 cm. deep holes made in the compost at a distance of 20-25 cm. Then you must cover the holes with compost.

    b) Surface Spawning

    In this case, you can evenly spray the spawn in the top layer of the compost. And then mix to a depth of 3-5 cm. Then, you must cover the top portion with a thin layer of compost.

    c) Layer Spawning

    In this method, mix about 3-4 layers of spawn with compost. Then cover it again with a thin layer of compost like in surface spawning.

    7. Casing and Pinning

    Apply a casing layer (usually a mixture of peat and limestone) to encourage pinning, the initial stage of mushroom formation.  The environmental conditions suitable for spawn runs are suitable for case runs as well.

    You can apply a casing 3-4 cm thick layer of soil on the top of the spawn run compost. The casing soil before application should be either pasteurized (at 66-700 C for 7-8 hours), treated with formaldehyde (2%), formaldehyde (2%), and Bavistin (75 ppm.), or steam sterilized. The treatment needs to be done at least 15 days before the material is used for the casing. Maintain the appropriate conditions for pinning to occur.

    8. Fruiting

    Create conditions for mushroom fruiting, including lower temperatures (around 12-18°C) and reduced humidity. Under favourable environmental conditions viz. temperature, moisture, humidity( above 85%), proper ventilation, and CO2 concentration, the fruit body initials. Generally, it appears in the form of pinheads that start growing and gradually develop into the button stage. Mushrooms should be ready for harvesting within a few weeks after pinning.

    9. Harvesting & Yield of Button Mushroom

    The first crop appears about three weeks after casing. And you can harvest the mushrooms by gently holding a mushroom body and twisting it. You can obtain about 10-14 kg. fresh mushrooms per 100 kg. fresh compost. However, the short method used for the preparation of compost under natural conditions gives more yield in the button mushroom cultivation business.

    10. Packaging and Distribution

    You need to properly harvest and package the mushrooms. Depending on your market, they can be packed in punnets, cartons, or bulk containers. Also, establish distribution channels, which may include local markets, grocery stores, restaurants, or direct-to-consumer sales.

    Frequently Asked Questions

    What are the Health Benefits of Button Mushrooms?

    First of all, it reduces inflammation in arterial cells and prevents white blood cells from sticking to arterial walls. Furthermore, the researchers conclude that consuming button mushrooms may be a means to prevent heart disease.

    Finally, this vegetable contains high amounts of copper. In addition, they are rich in nutrients like vitamins C, D, and B; and the minerals selenium, iron, magnesium, phosphorous, potassium, and zinc

    Is Button Mushroom Farming Profitable?

    The easily saleable product is the fresh mushroom. However, canned mushrooms in brine solution have potential retail values. This product also has a longer shelf life. Mushrooms are highly popular in Asian countries such as China, India, and Japan. Asia holds the majority of the market share of global mushroom consumption and is closely followed by North America and Europe. Europe is the leader in mushroom production and processing.

    The global mushroom market has shown remarkable growth in recent years and is also showing attractive market potential for the future. The major importing countries are the USA, UAE, Russia, The Netherlands, Germany, the UK, Switzerland, Denmark, Israel, and Sweden. However, the increasing development of high-yield systems, rising saturation in demand, and consumer shifts towards value-added products are the major driving factors.

    What are the Types of Equipment Required for Button Mushroom Farming?

    Below is the list of some other basic equipment and tools needed for button mushroom cultivation:

    • Composting Unit
    • Outdoor Phase-composting platform/indoor bunkers or aerated chambers
