Solan Mushroom City Farm Visit Guide 2026: ICAR-DMR Timings, Entry Rules & Cultivation Tours
Discover why Solan is the official "Mushroom City of India"! Explore the ICAR Directorate of Mushroom Research (DMR), climate-controlled cultivation chambers, spawn laboratories, and local farm tasting tours.
Can Tourists Visit Mushroom Farms and ICAR-DMR in Solan?
Yes, tourists, students, and farming enthusiasts can visit the ICAR-Directorate of Mushroom Research (DMR) located in Chambaghat, Solan. Entry is 100% free from Monday to Friday between 10:00 AM and 05:00 PM (closed on weekends & central holidays) upon signing the visitor register with government ID. Visitors can explore the national Mushroom Museum, view live medicinal species (Cordyceps, Ganoderma), and observe composting methodologies. Additionally, commercial button mushroom farms across Chambaghat and Basal offer experiential harvesting tours where travelers can see dark humidity-controlled growing racks and buy fresh mushroom pickles and spawn bottles.
The Science Behind the Title: Why Solan Became the 'Mushroom City of India'
While casual travelers know Solan for its pleasant British cantonment climate and fruit orchards, the town holds a prestigious global scientific distinction: on September 10, 1997, the Indian Council of Agricultural Research (ICAR) officially conferred upon Solan the title of "Mushroom City of India". This was not a marketing slogan, but an acknowledgment of decades of pioneering fungal biotechnology and commercial farming revolutions.
In the 1960s, the Food and Agriculture Organization (FAO) recognized that Solan's temperate elevation (1,500m / 5,000 ft), moderate humidity, and abundant wheat-straw raw materials from neighboring Punjab provided the exact microclimatic requirements needed for cultivating delicate Agaricus bisporus (White Button Mushrooms). What started as a modest UNDP experimental station evolved in 1983 into the National Centre for Mushroom Research and Training (NCMRT), later elevated to the Directorate of Mushroom Research (DMR).
Today, Solan is the technological nervous system of India's ₹3,000-crore mushroom industry. Almost every commercial grower in the country uses spawn strains, pasteurized compost formulas, or casing soil protocols originally engineered in Solan's laboratories. For travellers interested in agro-tourism, culinary science, and educational exploration, a mushroom farm visit offers an intellectually fascinating alternative to routine mountain viewpoints.

What You Will Learn: The 5 Scientific Stages of Mushroom Farming
During your tour of DMR or a local private farm in Chambaghat, you will observe the complete metamorphosis from agricultural waste into protein-rich fungi:
1. Organic Compost Formulation & Bunker Pasteurization
Unlike normal plants that photosynthesize using soil and sunlight, mushrooms are saprophytic fungi that feed on decomposed organic biomass. Farmers blend wheat straw, poultry manure, urea, and gypsum, fermenting the mixture in massive aerated bunkers at 58°C to 60°C to eliminate harmful wild moulds and nematodes.
2. Spawning (Mycelium Inoculation)
Once the compost cools to 25°C, it is "seeded" with mushroom spawn—sterilized wheat grains colonized by pure fungal mycelium cultures. The spawned compost is filled into polythene bags or placed on multi-tier wooden growing shelves.
3. Casing Layer Application
After 12 to 14 days of incubation in dark, warm rooms (where white spider-web-like mycelium spreads through the compost), a 3 to 4 cm layer of pasteurized peat moss, decomposed coir pith, or aged farmyard manure (casing soil) is spread over the top. This layer retains moisture and triggers the fungus to transition from vegetative growth into fruiting.
4. Pinhead Induction & Climate Control
The temperature is abruptly lowered to 15°C–17°C, fresh air is introduced to drop CO2 levels, and humidity is elevated to 85%–90% using high-pressure ultrasonic misting nozzles. Tiny white pearls—called 'pinheads'—miraculously erupt across the casing surface, doubling in size every 24 hours!
5. Harvesting (The Delicate Hand Twist)
Buttons are harvested by hand with a gentle clockwise twist just before the veil beneath the cap breaks open. A single compost bag yields 3 to 4 successive harvesting flushes over 6 weeks.

At ICAR-DMR, research extends far beyond daily culinary button mushrooms into ultra-high-value medicinal species:
🎉 The Annual National Mushroom Mela (Every September 10th)
If you can schedule your Solan trip in early autumn, plan your visit for September 10th. Every year on this date, the ICAR-DMR campus opens wide to thousands of progressive farmers, agriculture students, food scientists, and general tourists for the National Mushroom Mela:
- Live Gourmet Food Counters: Savor freshly prepared mushroom pakoras, spicy mushroom momos, mushroom burgers, mushroom soups, and traditional Himachali mushroom Madra cooked live on campus.
- Free Agro-Farming Workshops: Live interactive Q&A sessions on setting up low-cost small-scale home mushroom kits, terrace gardening with oyster bags, and spawn preservation.
- Subsidized Farm Sales: Farmers sell freshly harvested A-grade button and oyster mushrooms, certified spawn packets, and handmade organic mushroom pickles at subsidized wholesale prices.
