Casing is a staple part of mushroom cultivation with profound impact on fructification and crop yield. This survey aimed to scrutinize the influence of various casing alternative materialson the fruiting bodies, yield, and duration of production cycle of Agaricuss ubrufescens and Agaricuss bisporus. Evaluated casing treatments included common soil, Duch soil, spent mushroom compost from A. bisporus, vermicompost from spent mushroom compost, vermicompost from municipal solid waste, zeolite and their combinations as well.Using SPSS, analysis of data was conducted in a completely randomized factorial design and LSD test. The findings revealed that the highest productivity of A. bisporuswas obtained by using casing layer comprised of Duch soil + vermicompost from municipal solid waste (2:1).The most efficient casing for A. subrufescence were common soil + Duch soil (1:1),common soil + vermicompost from spent mushroom compost (2:1), common soil + vermicompost from municipal solid waste (2:1), respectively. Mixing vermicompost from spent mushroom compost and vermicompost from municipal solid waste with common soil led to substantial reduction of growth period and cropping period of A. subrufescence. In conclusion, this study highlight the efficiency of using vermicompost as an alternative casing material for both improving productivity and accelerating production cycle.
