Abstract

Oyster mushroom (Pleurotus spp.) is a popular edible mushroom known for its delicate flavor and nutritional value. Rice and wheat straw are the major substrates used for the production of mushroom. The use of different basal substrate has been a common practice for optimization of the C:N ratio, enhance the yield, nutritional and medicinal values. In the present investigation, eleven substrates were evaluated in two years respectively for 2020-21 and 2021-22 for the growth behaviour, fruiting body and its characteristics and biological efficiency of Oyster mushroom. After pooling the data of two years, significant effect of different substrates was recorded. The results of the present investigation revealed that wheat straw substrate recorded significantly less time for spawn run (14.65 days), pinhead initiation (19.725 days), 1st harvesting days (25.06 days), 3rd harvesting days (45.47 days) and 4th harvesting days (57.225 days). Supplementation with rice straw resulted into the best result for 2nd harvesting where it took 34.38 days. For fruiting body characteristics, Wheat straw exhibited the best result on the parameters of total no. of fruiting bodies (97.99), Maximum weight of fruiting body (25.84 gm), average length of stalk (7.85 cm), average width of stalk (2.79 cm), average diameter of mushroom cap (8.13 cm) and total diameter of mushroom (12.81 cm). For minimum weight of fruiting body with 7.84 gm, rice straw exhibited the finest response. Use of wheat straw enhanced the yield significantly in all four flushes with pooled total yield (965.53 g) and biological efficiency (96.20%). In a few of the observations Maize substrate and Sugarcane bagasse exhibited wonderful positive results. Overall, wheat straw and rice straw substrate were the best and maize straw, sugarcane bagasse were above par.

Conclusion

During the two consecutive years of continuous investigation, wheat straw followed by rice straw was found to be the best substrate for Oyster mushroom production whereas Mustard straw followed by lentil straw was the poorest performing substrate among eleven substrates tested.
