Objective: Beta-glucan is one of the components of the mushroom cell wall and the most therapeutically important polysaccharide in mushrooms. The aim of this research is to produce a specific vermicompost to improve the nutritional value and evaluate the beta-glucan content in blazai mushroom (A.subrufescens).
Methods: An experiment was conducted in form of a completely randomized design and in three replications at the mushroom research center of Islamic Azad University of Isfahan (Khorasgan) in 1399-1400. It investigated 18 combined substrates as treatments, including casing soil as control, compost and vermicompost, Echinacea vermicompost alone and in combination with casing soil with certain values of the hormone indol acetic acid. Based on the results, richer substrates including compost and vermicompost alone and in combination with casing soil led to the optimal growth of blazai mushrooms.
Results: The results of the analysis of variance showed that the highest amount of beta-glucan with the value of 72.86 mg/kg and the highest ash percentage was observed, namely the substrates with the origin of the Echinacea medicinal plant.
Conclusion: In general, for biomass production, it is better to use richer substrates, yet if the purpose of production of the essential material in the mushrooms, it is better to use substrates that are combined with Echinacea. The present research is the combination of casing soil 50 percent + compost or vermicompost 50 percent in the absorption of nutrients and the improvement of quantitative traits played a slightly better role.

Peat is the most important source of casing soil for growing mushroom. Peat often imported or derived from wetlands which have unfavorable environmental impacts. In order to evaluate the effects of the replacing vermicompost and perlite as casing soil instead of peat on growth and yield of the mushrooms (Agaricus bisporus), a factorial experiment was conducted on the randomized complete block design with three replications at Kosar mushroom farm in winter, 2015. Ten treatments in different ratios (volume percentage) of perlite: vermicompost: peat including T1 (0: 0: 100) T2: (0: 25: 75) T3: (12.5: 12.5: 75) T4: (16.7: 33.3: 50) T5 (25: 25: 50) T6: (18.5: 56.5: 25) T7 (25: 50: 25) T8: (37.5: 37.5: 25) T9: (33.3: 0: 66.7) T10 (50: 50: 0) were used. The maximum yield was obtained with T3 treatment with the average of 14.72 kg /m2 and the minimum yield was observed in T10 treatment with 9.43 kg/m2. The maximum and minimum numbers of harvested mushrooms were observed in treatment of T3 with 547 numbers and the treatment of T10 with the number of 244.67, respectively. For cap diameter, the treatment of T10 with an average of 5.9 cm had the maximum and the treatment of T9 with an average of 4.8 cm had the minimum cap diameter. For the average weight of individual mushroom, treatments of T10 and T3 with the average of 38 and 26 gr had the maximum and minimum weight of each mushroom, respectively. The results showed that T3 soil casing combination (12.5: 12.5: 75) can be replaced for peat.
