An experiment was conducted during rabi season 2016-17 in dark room on crop research farm of department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, SHUATS Allahabad. The experiment was laid out in Randomized Block Design with an objective of to study the growth, yield and nutrition content of mushroom with physical and chemical properties of soil which was used as growing of mushroom. There was 14 treatments combination replicated thrice. The different treatments were allocated randomly in each replication. Both the Mushroom varieties grown in 100% straw gave the significant maximum height, weight and width. Combination of 25% Soil + 75% Paddy Straw + Oyster Mushroom recorded significant maximum height, weight and width of mushroom. Treatment T12 (@ 25% Soil Science Soil + @ 75% Paddy Straw + Oyster Mushroom) was found to be at par with T2 (Paddy Straw @100% + Oyster Mushroom) in height, weight and width of mushroom. All the soil parameters viz., Bulk density (g cm-3), Particle density (g cm-3), Pore space (%), Water holding capacity (%), Organic carbon (%), Available Nitrogen (kg ha-1), Available Phosphorus (kg ha-1) and Available Potassium (kg ha-1) was also recorded maximum in treatment T12.
