Abstract: For Mushroom cultivation spawn is an essential component. Quality spawn has a great effect on the sporophores production. During the mushroom session, productions of quality spawn and its availability is a major challenge for mushroom growers. The present study was conducted with the aim to find out the most favourable inorganic and organic additives for the improvement of spawn growth of two Strains (CI-17-04 and CI-17-08) of Milky Mushroom (Calocybe indica). In the present Study different Inorganic and organic additives were mixed as a supplement with wheat grain for spawn production of Milky Mushroom (Calocybe indica). The results obtained during the present investigation, in case of inorganic additives maximum mycelial growth (90.00 mm) was found in ferrous sulphate @ 0.50% in Strain CI-17-04 and CI-17-08 while in case of organic additives maximum mycelial growth (90.00 mm) was found in Rice powder @ 1% in both strains. Based on the results obtained, ferrous sulphate and Rice powder would be recommended most effective inorganic and organic additives uses as supplement in Wheat grains for spawn production of Calocybe indica Strains (CI-17-04 and CI-17-08).
