Impact of Different Substrates and Mother Cultures on Yield and Yield Attributes of Oyster Mushroom (Pleurotus ostreatus)

Abstract

Aim: This study was aimed to compare the performance of different substrates and mother culture materials on yield and yield parameters of oyster mushroom (Pleurotus ostreatus).
 Study Design: This is an experimental study following Complete Randomized Design (CRD).
 Place and Duration of Study: The experiments were conducted in the Laboratory, Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka and Mushroom Development Institute, Savar, Dhaka from January 2019 to February 2020.
 Methodology: Accordingly, three substrates (sawdust, rice straw, sawdust + rice straw (1:1)) and three mother cultures (rice, maize, sawdust) were used in oyster mushroom cultivation.
 Results: Among the substrates and mother culture components, using rice straw and sawdust mother spawn, the maximum length of stipe was recorded (23.27 mm and 24.29 mm, respectively). Applying sawdust + rice straw (1:1) and maize mother spawn, the peak diameter of stipe was calculated (9.90 mm and 10.01 mm, respectively). The maximal diameter of pileus was observed in sawdust + rice straw (1:1) and rice mother spawn (72.90 mm and 67.57mm, respectively). With the application of rice straw and maize mother spawn, thickest pileus was viewed (5.60 mm and 5.47mm respectively). The sawdust and sawdust mother spawn delivered peak number of fruiting body (6.67 and 7.33, respectively). Among the substrates, rice straw gave the highest biological yield (44.40 g/packet) and sawdust gave the lowest (41.73 g/packet). Among the mother spawn, sawdust mother spawn presented the highest biological yield (45.47 g/packet) and maize mother spawn gave the lowest (39.16 g/packet). In the comparison of combined effect of substrates and mother spawn, sawdust mother spawn performed best in the biological yield (50.80 g/packet) with rice straw as substrate material and maize mother spawn showed comparatively lower biological yield (37.60 g/packet) with both sawdust and rice straw as substrate material.
 Conclusion: Rice straw and sawdust mother spawn can be recommended for its suitability in oyster mushroom (Pleurotus ostreatus) cultivation.

Potential Use of Cardunculus Biomass on Pleurotus eryngii Production: Heteroglycans Content and Nutritional Properties (Preliminary Results)

“…Cultivable mushrooms are grown successfully on different substrates such as cereal meals, brans, straw, sugar beet, etc., but their yield and chemical characteristics are strongly influenced by the composition of waste biomass [8].…”

Effects of Different Substrates on the Growth and Nutritional Composition of Pleurotus ostreatus: A Review

“…Waste materials from agriculture and industry can be used to grow mushrooms (Abid et al 2020;Iwuagwu et al 2020). Mushrooms are macrofungal fruiting bodies that are extremely rich in flavor and do not have high calories but are rich in vitamins, minerals, and proteins (Mubasshira et al 2020). Mushrooms are considered to be the world's most untapped resources for nutritious and healthy food (Kakon et al 2012).…”

“…(Garuba et al 2017). Previous research suggests that the consumption of oyster mushrooms can lower the risk of many diseases such as heart disease, impaired immune response, hepatitis B, liver disease, high blood cholesterol levels, gastric cancer, microbial infection, chronic fatigue syndrome, kidney problems, hypertension, and diabetes (Mubasshira et al 2020;Ba et al 2021;Krittanawong et al 2021). Therefore, oyster mushrooms are an alternative rich source of nutrition and an alternative food source that can promote human health (Valverde et al 2015).…”

“…P. ostreatus contain lignocellulosic enzymes that can convert lignocellulose residues into protein-rich biomass (Adebayo and Martinez-Carrera 2014;Mubasshira et al 2020;Grimm et al 2021). These mushrooms require a short growth time relative to other mushrooms and are economical to produce commercially (Abid et al 2020).…”
