Abstract: Tricholoma giganteum is the best mushroom for summer season having pleasant taste and good shelf life. The main objective of present study is to develop cultivation technologies for T. giganteum by recycling of locally available agricultural wastes to enhance farmer’s income. Five local isolates [CIP-12, CIP-17, CIP-18, CIP-19 and CIP-20] of T. giganteum were evaluated for yield potential against different parameters and result indicated that PDA (66.55) was the best media for radial growth (mm) of T. giganteum at 32 ⁰C (66.94) followed by Malt Extract Agar (52.66), Wheat Straw Extract (50.94), Wheat + Paddy Straw Extract (46.83) and Maize Stone Extract (26.11) in case of media, and 35 ⁰C (34.66), 38 ⁰C (23.27) and 40 ⁰C (11.22) in case of temperature. Among all substrates, wheat straw was proved superior and gave maximum yield in terms of per100 kg dry substrates (57.2kg) followed by Wheat + Paddy Straw (1:1) gave 51.0 kg but there is no fruiting was developed on Maize Stone alone. Among all casing materials Soil + Sand (3:1 ratio) was proved best which gave maximum yield in per100 kg dry substrates (71.0kg) followed by Spent Mushroom Compost (SMC) + Sand + Soil (1:1:1 ratio) gave 56.2kg and Soil alone gave minimum 50.6kg yield.
