Mycelial Performance and Primordial Development of Volvariella volvacea in Different Leaf Litter

Volvariellavolvacea commonly known as paddy straw mushroom is a tropical mushroom that is widely grown in Southeast Asia due to its favorable taste and ideal tropical condition for its proliferation. One of the most vital factor in V. volvacea production is its spawning material. This are commonly plant materials and considered as agro industrial waste. V. volvacea belong to leaf litters which thrive in rice straw and banana leaves. Thus, this study specifically intends to: determine the mycelial performance and primordial development of V. volvacea in the combination of dried leaves of cacao (Theobroma cacao), acacia (Samaneasaman), rice (Oryza sativa) straw and banana (Musa spp.). Each combination was added with 30% of sawdust. Completely randomized design was used for the experimental design. The ideal combination for spawning substrate were noted in treatment eight (35% acacia leaves + 35% cacao leaves + 30% sawdust) since it elucidated luxuriant mycelial run with zonation pattern. In addition, the shortest period of primordial development was noted with a mean of
6.33 days of incubation in treatments five (35% banana leaves + 35% cacao leaves + 30% sawdust), six (35% banana leaves + 35% acacia leaves + 30% sawdust) and seven (35% banana leaves + 35% rice straw + 30% sawdust). Moreover, this study revealed that all the test combination was colonized with
mycelia which indicates that the evaluated materials which are considered as locally available and abundant in the farming community of CBSUA-Sipocot can be utilized as spawning materials for the production of V. volvacea. This is an economically eco-friendly approach in dealing with agro industrial waste of the locality.
