Farming of Mushroom: Complete Guide to Mushroom Farming in India
Farming of mushroom, commonly called mushroom farming or mushroom cultivation, is the process of growing edible mushrooms under controlled or semi-controlled conditions for food and commercial purposes.
Unlike traditional crops that require large areas of agricultural land, mushroom cultivation can often be carried out in relatively small spaces such as rooms, sheds or low-cost growing structures. This makes mushroom farming an interesting agricultural activity for small farmers, rural entrepreneurs and people looking for additional sources of farm income.
In India, mushrooms are increasingly being explored as a high-value agricultural and rural enterprise. ICAR has highlighted oyster mushroom cultivation as an opportunity for small and marginal farmers, including cultivation using locally available agricultural residues such as paddy straw.
This guide explains farming of mushroom, the major types of mushrooms grown in India, how mushroom cultivation works, the basic requirements, benefits, challenges and business opportunities.

What Is Mushroom Farming?
Mushroom farming is the commercial or controlled cultivation of mushrooms for consumption and sale.
Mushrooms are fungi rather than conventional green plants. They do not depend on sunlight for photosynthesis in the way most crops do.
Instead, cultivated mushrooms grow on suitable organic materials called substrates.
Depending on the mushroom species, substrates can include materials such as:
Paddy straw
Wheat straw
Maize residues
Sawdust
Agricultural waste
Other suitable plant-based materials
ICAR research has documented the cultivation of oyster mushrooms on wheat straw, paddy straw and maize stalks and leaves.
This ability to use agricultural residues is one reason mushroom cultivation can fit well into diversified farming systems.
What Is Farming of Mushroom?
The phrase “farming of mushroom” refers to the process of cultivating mushrooms under suitable environmental and production conditions.
In simple terms:
Farming of Mushroom = Mushroom Cultivation
The process generally involves:
Substrate preparation → Spawning → Incubation → Fruiting → Harvesting → Packaging → Selling
Unlike field crops, mushroom cultivation requires careful management of environmental conditions such as:
Temperature
Humidity
Ventilation
Light
Cleanliness
Moisture
Substrate quality
The exact requirements depend on the mushroom species being cultivated.
Why Is Mushroom Farming Important?
Mushroom cultivation has several characteristics that make it attractive as a component of diversified agriculture.
1. Requires relatively little land
Mushrooms can be cultivated vertically or in controlled indoor spaces.
This means production does not necessarily require large agricultural fields.
2. Can use agricultural residues
Materials such as paddy straw can be used as substrates for some mushroom varieties.
This can convert agricultural residues into a potentially valuable farm output.
ICAR has documented oyster mushroom cultivation using paddy straw and other locally available resources as an additional income opportunity for farmers.
3. Can support additional farm income
Mushroom production can be added alongside traditional crop farming.
For some farmers, this creates an additional source of income without requiring a major expansion of cultivated land.
4. Short production cycles
Certain mushroom varieties can have relatively short cultivation cycles under appropriate conditions.
For example, ICAR reported a 30–35 day cultivation cycle for King Oyster under the specific controlled conditions used in its 2026 Arunachal Pradesh demonstration.
However, production time varies considerably by mushroom species and growing system.
5. Opportunities for value addition
Mushrooms can be sold fresh or processed into products such as:
Dried mushrooms
Mushroom powder
Pickles
Ready-to-cook products
Other processed foods
ICAR has documented farmer groups using value addition such as dried mushroom, mushroom powder and pickles to extend market opportunities.
Types of Mushrooms Grown in India
Several mushroom varieties can be cultivated in India.
The most important categories include:
Button mushroom
Oyster mushroom
Milky mushroom
Paddy straw mushroom
Specialty mushrooms
The suitable variety depends heavily on the local climate, infrastructure, market demand and cultivation technology available.
1. Oyster Mushroom Farming
Oyster mushroom farming is one of the more accessible forms of mushroom cultivation.
Oyster mushrooms belong primarily to the Pleurotus group and can be cultivated using agricultural residues such as paddy straw.
ICAR has specifically promoted oyster mushroom cultivation as an additional income opportunity for small and marginal farmers.
Oyster mushroom cultivation can be attractive because:
It can use agricultural residues.
It can be carried out indoors.
It does not necessarily require expensive infrastructure at small scale.
Several strains are available.
It can be suitable for diversified farm enterprises.
ICAR has also highlighted pink oyster mushroom cultivation using paddy straw in its 2025 farmer advisories.
2. Button Mushroom Farming
Button mushrooms are among the best-known cultivated mushrooms in India.
They typically require more controlled environmental conditions than some other varieties.
Button mushroom cultivation involves preparing a suitable compost-based growing medium, spawning, maintaining appropriate environmental conditions and managing the fruiting stage.
Because environmental control is important, commercial button mushroom production may require greater investment in infrastructure than some low-cost oyster mushroom systems.
3. Milky Mushroom Farming
Milky mushroom is another mushroom cultivated in India, particularly in warmer conditions.
It can provide an alternative to varieties that require cooler growing environments.
ICAR has included button, oyster and milky mushrooms among the mushroom production opportunities promoted through training and extension programmes.
4. Paddy Straw Mushroom Farming
Paddy straw mushroom is cultivated using straw as a growing substrate.
This variety can be particularly relevant in rice-growing regions where paddy straw is readily available.
Using agricultural residues for mushroom production can also contribute to a waste-to-wealth approach to farming.
5. Specialty Mushroom Farming
India's mushroom sector is also expanding into specialty varieties.
Examples include:
Shiitake
King Oyster
Lion's Mane
Enoki
Other specialty mushrooms
Specialty mushrooms can target premium consumer segments, restaurants, hotels and specialised food markets.
ICAR reported successful King Oyster cultivation under mid-hill conditions in Arunachal Pradesh in January 2026, demonstrating the potential for specialty mushroom diversification in suitable regions.
How Does Mushroom Cultivation Work?
Although the exact method varies by mushroom species, commercial mushroom cultivation generally follows a series of steps.
Step 1: Select the Mushroom Variety
The first decision is selecting a variety suitable for:
Local climate
Available infrastructure
Available substrate
Market demand
Production experience
Investment level
For beginners, the choice should not be based only on the selling price.
The variety should also be technically suitable for the growing environment.
Step 2: Prepare the Growing Area
Mushrooms are generally grown in protected environments.
The growing area should allow the farmer to manage:
Temperature
Humidity
Ventilation
Cleanliness
Light conditions
Depending on the scale, this could be a dedicated mushroom house, shed, room or other suitable structure.
Step 3: Prepare the Substrate
The substrate provides the material on which the mushroom grows.
Depending on the species, this can include:
Paddy straw
Wheat straw
Maize residues
Sawdust
Other suitable agricultural materials
The substrate generally needs appropriate preparation before spawning.
Step 4: Add Spawn
Spawn is the planting material used to establish mushroom mycelium in the prepared substrate.
Quality spawn is extremely important for successful cultivation.
The 2026 ICAR AICRP-Mushroom workshop specifically highlighted the importance of strengthening spawn availability and developing reliable spawn certification systems.
Farmers should therefore source spawn from reliable and technically competent suppliers.
Step 5: Incubation
After spawning, the bags or growing units are maintained under conditions suitable for mycelial growth.
During this stage, the mushroom mycelium gradually colonises the substrate.
The required conditions vary depending on the species.
Step 6: Fruiting
Once the substrate is adequately colonised, environmental conditions are adjusted to encourage mushroom fruiting.
This stage requires careful management of:
Temperature
Humidity
Fresh air
Moisture
Light where applicable
Step 7: Harvesting
Mushrooms are harvested when they reach the appropriate stage for the intended market.
Harvesting needs to be handled carefully to minimise damage and contamination.
Step 8: Packaging and Selling
Fresh mushrooms are highly perishable, making post-harvest handling particularly important.
Depending on the business model, mushrooms can be sold through:
Local markets
Retail stores
Restaurants
Hotels
Supermarkets
Direct-to-consumer sales
Online channels
Food processors
Value-added products can provide additional market opportunities.
Requirements for Mushroom Farming
Before starting mushroom cultivation, farmers should understand the major resources required.
1. Growing Space
A suitable protected space is required.
The size depends on the production target.
2. Quality Spawn
Reliable spawn is one of the most important inputs.
Poor-quality or contaminated spawn can significantly affect production.
3. Suitable Substrate
The substrate must be appropriate for the selected mushroom species.
4. Water
Clean water is required for substrate preparation and maintaining appropriate growing conditions.
5. Temperature Control
Different mushrooms require different temperature ranges.
Choosing the mushroom variety according to the local climate can reduce the need for expensive environmental control.
6. Humidity Management
Mushrooms generally require high humidity during important stages of production, but excessive moisture and poor ventilation can increase contamination risks.
7. Ventilation
Adequate fresh air is important for healthy mushroom development.
8. Hygiene
Clean cultivation areas, equipment and handling practices are essential for reducing contamination.
Mushroom Growing Substrate
The substrate is one of the most important components of mushroom cultivation.
Different mushrooms prefer different substrates.
Common materials include:
Paddy straw
Wheat straw
Maize residues
Sawdust
Agricultural by-products
Oyster mushrooms are particularly versatile in this regard.
ICAR has documented oyster mushroom cultivation using paddy straw, wheat straw and maize stalks and leaves.
More recent ICAR work has also demonstrated oyster mushroom cultivation using large cardamom residues as an alternative substrate, showing how local agricultural waste streams can potentially be converted into mushroom production inputs.
Temperature and Humidity Requirements
One of the biggest differences between mushroom cultivation and conventional field farming is the importance of environmental control.
There is no single temperature or humidity requirement for all mushrooms.
For example, ICAR reported that King Oyster required approximately 20–23°C during vegetative growth and 15–18°C during fruiting under its specific cultivation conditions.
Other mushroom varieties have different requirements.
Therefore, farmers should always follow the cultivation protocol recommended for the specific strain rather than using a generic temperature chart.
Mushroom Farming in India
India has significant potential for mushroom cultivation because of its diverse climate, agricultural residues, growing food markets and large rural population.
Mushroom cultivation can also complement conventional agriculture.
For example:
Rice farming → Paddy straw → Mushroom cultivation → Fresh mushroom → Value-added products → Local market
This creates a circular agricultural model in which a farm residue can become an input for another enterprise.
ICAR has highlighted mushroom cultivation as a way of converting agricultural waste into value while supporting farmer and entrepreneur incomes.
Benefits of Mushroom Farming
Additional Income
Mushroom cultivation can provide an additional source of income alongside conventional crops.
Efficient Use of Space
Production can be carried out in protected spaces rather than requiring large areas of farmland.
Agricultural Waste Utilisation
Certain mushroom varieties can use crop residues as growing substrates.
Value Addition
Farmers can sell fresh mushrooms or develop processed products.
Employment Opportunities
Mushroom enterprises can create opportunities for rural households, women, youth and agricultural entrepreneurs.
ICAR's field experience in Jharkhand has documented mushroom cultivation becoming an additional income activity for farmers and the development of farmer groups around mushroom production and value addition.
Mushroom Farming as a Business
Mushroom farming can be approached as a small-scale, medium-scale or commercial agricultural enterprise.
However, profitability depends on several factors.
A basic mushroom business model can be represented as:
Spawn + Substrate + Labour + Infrastructure + Utilities
↓
Mushroom Production
↓
Sorting + Packaging
↓
Local / Institutional / Retail Market
↓
Revenue
Farmers should calculate their business economics based on their actual:
Production capacity
Spawn cost
Substrate cost
Labour cost
Electricity
Water
Infrastructure
Packaging
Transportation
Expected selling price
Spoilage
Market demand
There is no universal mushroom farming profit figure because production costs and selling prices vary substantially by mushroom type, location, scale and market.
How to Market Mushrooms
Producing mushrooms is only half of the business.
The other half is finding reliable buyers.
Potential channels include:
Local Markets
Farmers can sell fresh mushrooms directly through local vegetable and food markets.
Restaurants and Hotels
Restaurants can provide recurring demand, particularly for specialty varieties.
Retail Stores
Supermarkets and speciality food stores can become useful distribution channels.
Direct-to-Consumer
Farmers can build local customer bases through:
WhatsApp
Social media
Local delivery
Subscription models
Community groups
Processed Products
Mushrooms can potentially be converted into:
Mushroom powder
Dried mushrooms
Pickles
Ready-to-cook products
Other packaged foods
The 2026 ICAR mushroom workshop specifically emphasised value-added products as a route to improving farmer incomes and extending shelf life.
Challenges in Mushroom Farming
Mushroom farming can be profitable, but it is not risk-free.
1. Contamination
Contamination can damage entire batches.
Strict hygiene and appropriate production practices are essential.
2. Temperature Management
The wrong temperature can negatively affect mushroom growth and fruiting.
3. Humidity Management
Insufficient or excessive moisture can create production problems.
4. Short Shelf Life
Fresh mushrooms can be highly perishable.
This makes efficient harvesting, packaging, transportation and selling important.
5. Market Risk
A farmer may successfully produce mushrooms but still face difficulty if there are insufficient buyers.
6. Quality Spawn
Reliable spawn is essential for consistent production.
7. Technical Knowledge
Mushroom farming is not simply a matter of placing spawn in a bag and waiting for mushrooms to grow.
Farmers need to understand the requirements of the selected species and follow appropriate production protocols.
Role of Technology in Mushroom Farming
Technology is increasingly influencing mushroom production.
Potential applications include:
Temperature sensors
Humidity sensors
Automated ventilation
Smart irrigation or misting
Environmental monitoring
Digital farm records
Production analytics
Online marketplaces
For larger farms, environmental monitoring can help maintain more consistent growing conditions.
For smaller farms, low-cost sensors and simple digital monitoring tools can also improve decision-making.
Sustainable Mushroom Farming
Mushroom cultivation can fit well into sustainable agriculture when agricultural residues are used effectively.
For example:
Agricultural residue → Mushroom substrate → Mushroom production → Spent substrate → Compost / soil amendment
Spent mushroom substrate can potentially be reused as an organic input after appropriate processing.
ICAR has documented farmers recycling spent mushroom media through vermicomposting and using the resulting vermicompost in vegetable production.
This creates an opportunity to connect mushroom farming with broader circular agriculture.
Future of Mushroom Farming in India
The future of mushroom farming in India is likely to be shaped by several trends.
1. More Specialty Mushrooms
Premium varieties such as King Oyster and other specialty mushrooms can target restaurants, hotels and higher-value consumer segments.
ICAR's 2026 King Oyster work illustrates the continuing expansion of mushroom cultivation beyond conventional varieties.
2. Better Spawn Production
Reliable access to quality spawn will remain essential for expanding mushroom cultivation.
The national mushroom research programme is actively discussing spawn availability and certification.
3. More Value Addition
Dried mushrooms, powders, pickles and other products can help extend shelf life and create additional revenue opportunities.
4. Greater Use of Agricultural Waste
More research is likely to explore locally available crop residues as mushroom substrates.
5. Integration with Rural Businesses
Mushroom farming can increasingly become part of broader rural enterprises involving:
Farmer Producer Organisations
Self-help groups
Food processing
Rural entrepreneurship
Direct-to-consumer sales
Local food businesses
