6. INTRODUCTION
Mushrooms have been consumed since earliest history; ancient Greeks believed
that mushrooms provided strength for warriors in battle, and the Romans perceived
them as the “Food of the Gods.” For centuries, the Chinese culture has treasured
mushrooms as a health food, an “elixir of life.”
 Nowadays, mushrooms are popular valuable foods because they are low in
calories, carbohydrates, fat, and sodium: also, they are cholesterol-free.
Besides, mushrooms provide important nutrients, including selenium, potassium,
riboflavin, niacin, vitamin D, proteins, and fiber.
 All together with a long history as food source, mushrooms are important for their
healing capacities and properties in traditional medicine. It has reported beneficial
effects for health and treatment of some diseases.
 Mushroom cultivation ,was started in the early 17th century by French
horticulturists, and became a thriving industry only by 1850 in Paris.

7. WHAT IS MUSHROOM ?
A mushroom or toadstool is the fleshy,spore bearing fruiting body of a
fungus ,typically produced on ground,wood or any other decaing
matters from which they satishfy their Saprophytic mode of
nutrition.They mostly belongs to Ascomycota and Basidiomycota fungal
phylums.

9. MUSHROOM CULTIVATED COMMERCIALLY IN INDIA
 White button mushroom (Agaricus bisporus)
 Oyster or Dhingri mushroom (Pleurotus
spp.)
Paddy straw mushroom (Volvariella
volvacea)
White milky mushroom (Calocybe indica)

10. CULTIVATION OF OYSTER MUSHROOM
 Oyster mushroom (Pleurotus sp.) belonging to
Class Basidiomycetes and Family Agaricaceae is
popularly known as ‘Dhingri’ in India.
 It grows naturally in the temperate and tropical
forests on dead and decaying wooden logs or
sometimes on dying trunks of deciduous or coniferous
woods. It may also grow on decaying organic matter.
The fruit bodies of this mushroom are distinctly
shell or spatula shaped with different shades of
white, cream, grey, yellow, pink or light brown
depending upon the species.
It is one of the most suitable fungal organisms for
producing protein rich food from various agro-
wastes or forest wastes without composting.

11. ORIGIN OF OYESTER MUSHROOM
ORIGIN-Cultivation initiated on experimental basis in Germany by Flack
during the year 1917 on tree stumps and wood logs. Growing technology
was perfected in USA by Block, Tsao and Hau. Cultivation of different varieties
of oyster mushroom was initiated in India in the early sixties.

12. BOTANICAL DESCRIPTION OF OYSTER MUSHROOM
The oyster mushrooms have three distinct
parts-
• a fleshy shell or spatula shaped cap (pileus)
• a short or long lateral or central stalk
called stipe
• long ridges and furrows underneath the
pileus called gills or lamellae. The gills
stretch from the edge of the cap down to the
stalk and bear the spores.
•The spores are smooth, cylindrical and
germinate very easily on any kind of
mycological media within 48-96 hrs.
• The mycelium of many Pleurotus species
are pure white in colour.

13. DIFFERENT TYPES OF OYESTER MUSHROOM

PROJECT PROPOSAL ON ESTABLISHING AN
OYESTER MUSHROOM PRODUCTION UNIT

19. PRODUCTION TECNOLOGY OF OYSTER MUSHROOM
Cultivated types of Oyster mushroom- Mainly
white oyster mushroom.
Propagating materials-
Oyster mushrooms are grown from mycelium
(threadlike filaments that become interwoven)
propagated on a base of steam-sterilized cereal
grain (usually rye or millet).
This cereal grain/mycelium mixture is called spawn
and is used to seed mushroom substrate.
Spawn materials are provided by local whole
sellers at the cost of 15/- per 100 g.
Required climatic condition-Oyster mushroom can
grow at moderate temperature ranging from 20 to 30
degree C and humidity 55-70% for a period of 6 to 8
months in a year. It can be cultivated during summer
months.
COMPONENTS and CONDITIONS REQUIRED

20. Growing seasons-
 The best growing season is from March –
April to September-October.
Generally ,at least 3-4 cuts can be
successfully taken from this 2 months growth
period of each batch.
It takes about 30-45 days to get the desired
harvest from spwaned bags.
 Polythene bags, bamboo poles, coco-rope
for roping of bags.
Big containers for substrate preparation.
Water source- Pump
watering equipments- water tank, sprayers, hand
sprayers.
 Other instruments-
 Weighing balance
 Thermometer
knife

23. DIFFERENT STEPS IN THE PROCESS OF PRODUCTION
1.PROCUREMENT OF SPAWN
2.PREPARATION OF SUBSTRATE/STERILIZATION OF SUBSTRATE
Generally paddy straw is used as substrate.for preparing substrate following
actions are taken-
Chopping of straw in 1-2 inchs.
Treating the chopped straw with lime water and Formalin for 24 hours.
Removing extra water from moist straw and mixing with the mixture of
lime powder and fungicides like Mancozeb or Carbendazim etc.
Spawn is procured from local spawn production unit@ of 15/- per 100 gm.Then
they are kept in refrigerator for future use.

24. 3.BAGGING OF SUBSTRATE- Generally bags of 4 kg substrate are prepared.
4.INOCULATION/ SPAWNING
Spawns are spread by hands around the perifery of the polythene bag layer by layer
followed by perforating the bag with a sterilized needle at suitable places and plugging
them with cotton.For 1 bag 400g spawn are required.
5.INCUBATION- Spawned bags are allowed to incubate by hanging them with ropes in
Growing room.Frequent watering is needed to avoid drying of the substrate.

25. SPAWN

26. STEPS IN A NUTSHELL

27. 6.OPERATIONS DURING GROWTH PERIOD
1.Frequent spraying of water is required in the
cropping room depending upon the atmospheric
humidity.
2. Contaminated bags with moulds may be
discarded by regular observations.
3. Proper management of temperature and
humidity during growing period by
providing ventilation and watering .Temperature
more than 30 degree C inhibits growth and kills
the mycelium.
During mycelium growth, the bags are not to
be opened or no ventilation needed.

28. 4.DISEASE MANAGEMENT
The crop is prone to fungal diseases. Several competitor moulds
( Aspergillus sp. Cladosporium sp. and Fusarium sp., Rhizopus sp.)have been
reported to occur in the substrate used for cultivation.
Spraying with Bavistin or Benomyl is a recommended control measure.

29. 7.HARVESTING AND YIELD
Generally after 30-35 days of spawing mushroom fruitbody reaches the stage
of harvesting,and it continues upto 20-30 days after first harvest.Normally 3-
4 cuts can be taken from each bag of 4 kg substrate and such bag yields
about 4-5 kg in its total harvest period.
The right shape for picking can be judged by the shape, size, colour
(yellowish)of the fruit body.
Harvesting is done by removing the mushroom completely by twisting
firmly at its base. It is advisable to pick all the mushrooms at one time from a
cube and the next flush will appear at one time.Harvesting is done with hands
very carefully without touching any buds or tearing poly bags.

30. 8.STORAGE & POST- HARVEST MANAGEMENT
Fresh mushrooms have a short shelf life. Therefore it is necessary that they are either
marketed soon after harvesting or preserved with special care such as in cold storage or
other controlled environment storage.
Short-term Storage: Fresh mushrooms are packed in perforated polythene bags
which are directly sent to the local market situated nearby. Freshly harvested
mushrooms can be stored at low temperature (0-50 degreeC) for 1-2 weeks without
loss in quality in case it is to be sent to the distant markets.
Long-term Storage: Dried mushroom with 2-4% moisture, can be stored for 3-4
months in sealed pouches without any change in taste. The dried produce can be
rehydrated in luke warm water (40-50degreeC) within 20-30 mins. giving 80-90% of
original weight.
 Processing-Many products can be made from mushrooms. Apart from being
processed into soups and sauces, mushrooms can be processed into sweets, cookies,
candies and various snacks,pickles etc. In a nutshell, these are some ways of adding
value to mushrooms.

31. 9.PACKAGING
Mushrooms should be fresh and packed in perforated polythene bags and tied
with rubber bands or in sealed plastic wrapper (after weighting) . Mainly
packets of 500gm or 1kg are made.
10.MARKETING
Some ideal market places are:
•On farm marketing, Local / Open
market, Restaurants and hotels,
catering agencies etc.
• Advertisement through social
media like whatsapp , facebook,
Instagram etc.
•Newspaper

32. PROBABLE RISK /CHALLENGES OF THE FARM
The dearth of availability of quality spawn- proper availability of quality
spawn must be ensured.
 High risk of contamination-proper hygiene must be maintained.
 Possible flies, many mushroom diseases- verticillium, mildew,
trichoderma, nematodes etc.
 Lack of proper market and marketing channels.

continues for 2 months(60 days).

36. Total production and income-
Out of total production 95% are best harvest and are
suitable for sale.
Yield per bag- 5kg(average)
So, total production from 400 bags= 2000kg
Therefore 95% of 2000kg=1900kg
Market price per kg of mushroom-100/-
Expected total gross return=190000/- per season
Now, expected average gross return per
month=190000/2=95000/-
.

37. Expected net profit/month=(95000-36542)=58458/-per
month
Expected benefit / cost ratio = 2.5 :1
Therefore,the project is technically feasible and commercially viable.

38. Compacted information on mushroom cultivation in relation to production,
performance, problems and prospects is very important for developing this sector
. So, the aim of the review paper is to compile information on oyster mushroom
cultivation.
Mushroom production is increasing due to high demand of domestic market
and export potentiality. Nowdays, mushroom cultivation is the most productive
and profitable business in India because in a short period of time it converts
farmers hard work into profit.
Mushroom production in India mainly done in Panjab,Hariyana,Himachal
Predesh,UP,Kerala,Tripura etc. Panjab is the leading state contributing
about 50% of the total production.
Oyster, Button and paddy straw mushrooms are most preferable species and
cultivated by the Indian farmers; but the wide cultivation is confined to oyster
mushroom (Pleurotus spp.) which are grown throughout the year.
 Mostly young aged educated people and Rural women are adopting mushroom
farming as a commercial basis in West Bengal. The study revealed that
mushroom production is easy work because it requires only a little technical
efficacy and a highly profitable agribusiness as evident for its lucrative benefit
cost ratio (BCR 1.55-4.25) .
CONCLUSION

39. EXPERIENCE WE GAINED FROM THIS PROJECT
Gaining professional skills and knowledge through hands on experience like
trainees.
Building capability and confidence to work in project mode and acquire enterprise
Management capabilities.
By involving in such project work we came across the concept “learning by doing:.
We,the team members, faces so many problems while doing this work,but we could
solve these out finally by critically examing the various steps ,different skills and tech-
niques,the pros and cons of this production infrastructure ,we can easily draw out that
we had a great team work,experiencing different view-points regarding a same
problem which has helped us in exploring our knowledge and skills at different levels
regarding Agri-entrepreneurship.
