5 1 cultivation of oyster mushroom

The document discusses the cultivation of oyster mushrooms. It describes the key steps as: preparation of spawn/seed by inoculating wheat grains with fungal mycelium; preparation of the substratum or growing medium by processing materials like rice straw or bagasse; cultivation using the cylindrical block system by layering spawn and substratum in bags; maintaining proper temperature and humidity during growth; harvesting mushrooms after 3 weeks by handpicking; and storing fresh mushrooms for 1-2 days or drying for longer storage. Oyster mushrooms are the second most cultivated edible mushroom globally.

NME -BOTANY -CULTIVATION OF OYSTER MUSHROOM OYSTER MUSHROOM Pleurotus ostreatus is commonly known as Oyster Mushroom. The Fruit Bodies of this Mushroom are distinctly Shell Shaped. It is the Second Most Cultivated Edible Mushroom next to Button Mushroom. It Grows in 20-300C Temperature and their Fruiting Bodies are Not Easy to Attack by any Pathogens and Pests. BOTRVMSBKCAPK

CULTIVATION OF OYSTER MUSHROOM -PREPARATION OF SPAWN or SEED PREPARATION OF SPAWN or SEED ⚫ Wheat Seed with Fungal Mycelium called Spawn or Fungal Seeds. ⚫ Wash the Wheat Seeds in Water. ⚫ Dry the Seeds Under Shade. ⚫ Boil the Seeds in Water for 50 minutes. ⚫ Dry the Seeds in air by spreading on polythene sheet. ⚫ Coat the Seeds with 2% Calcium Carbonate and 1 % Chalk Powder to adjust the pH around 7 and also keeping the Seeds in individuals. ⚫ Fill 250 g Seeds (Substrate) in Glass Bottle. ⚫ Close the Mouth by Cotton Plug for Good Aeration and also Prevents the Entry of Microbes. BOTRVMSBKCAPK
CULTIVATION OF OYSTER MUSHROOM -PREPARATION OF SPAWN or SEED • Sterilize in Autoclave at 121ºC for 30 minutes and then Cool. • Inoculate the Pure Mycelium of Pleurotus ostreatus into the Bottle in Laminar Flow Chamber. • Incubate at 25ºC for 10-12 Days for Fungal Growth. • During Incubation, the Mycelium Grown in to Dense Mycelia on Wheat Grains to form Spawn. • The Spawn is used for the Cultivation of Mushroom. BOTRVMSBKCAPK
CULTIVATION OF OYSTER MUSHROOM -PREPARATION OF SUBSTRATUM PREPARATION OF SUBSTRATUM Organic Waste that used for Mushroom Cultivation is called Substratum STEPS IN SUBSTRATUM PREPARATION ⚫ Cut the Paddy Straw or Sugarcane Bagasse in to 2.5 cm Size Pieces. ⚫ The Sugarcane Bagasse is Performed for the Best Production of Oyster Mushroom when compared to Paddy Straw. ⚫ Soak in Water for 24 Hours. ⚫ Boil in Water for One Hour. ⚫ Dry Under the Shade the Pasteurized Substrates. But Maintains Moisture Content up to 65 – 70% ⚫ Spray 10 % Calcium Carbonate Solution for Maintain the pH around 7. ⚫ Add Rice Bran, Gypsum and Molasses For High Yield. ⚫ Now, the Substrate Mixture is Ready for Mushroom Cultivation. ⚫ Use Polypropylene Bags (60 X 30 cm) for the Cultivation of Mushroom. BOTRVMSBKCAPK
CULTIVATION OF OYSTER MUSHROOM - METHOD OF CULTIVATION METHOD OF CULTIVATION ⚫ The Cylindrical Block System is Better for Oyster Mushroom Cultivation. ⚫ Take the Substrate Mixture in Polypropylene Bag about 5 cm Height as a First Layer. ⚫ Spread 50 gms of Spawn on the Substratum. This Process called Spawning. ⚫ Make the Second Layer of Substratum about 10 cm Height. ⚫ Spread 50 gms of Spawn on the Substratum, mostly on the Periphery. ⚫ Repeat this Process for Several Times in the Same Manner. ⚫ Finally, the Spawn Covered with 5 cm Height of Substratum. ⚫ Make Many Holes on the Surface of the Bag for Watering, Good Aeration and Reduce Temperature. ⚫ Tie the Mouth of Bag with Thread.

CULTIVATION OF OYSTER MUSHROOM - AFTERCARE . BOTRVMSBKCAPK AFTERCARE • Keep the Cylindrical Block Bed on the Racks or in Hanging Position Under the Cultivation Room or Shed. • Sprinkling of Water Twice a Day with a Very Fine Sprayer, keeping its Nozzle Upside and Droplets Allowed to Come Down Very Slowly and Maintain the Temperature Between 20-300C and Humidity about 80-85% .
CULTIVATION OF OYSTER MUSHROOM - AFTERCARE • Spawn Grows into Dense Mycelium inside the Bag with in 10 -12 Days. • After15 days, Remove the Polypropylene Bag and Expose the Bed in which Mycelium starts to Develop into Knots called Pin Head Stage. • After 4-6 Days, the Pin Head Stage Develops in to Shell Shaped Oyster Mushroom. BOTRVMSBKCAPK
CULTIVATION OF OYSTER MUSHROOM - HARVEST and STORAGE HARVEST and STORAGE ⚫ After 21 Days of Spawning, starts to Harvest the Mushroom. ⚫ Harvest the Mushroom by Handpicked Method. ⚫ Harvest Minimum of about 500 to 700 kg of Fresh Oyster Mushroom from One Ton of Dry Paddy Straw in 45-60 Days. ⚫ Remove the Dust Particles from Mushroom by Sterilized Forceps. ⚫ Fresh Mushrooms have a Shelf Life of 24-48 Hrs even at Room Temperature ⚫ The Oyster Mushroom can be Easily to Dry and Stored in Powdered Form for Future Use.
