Effect of Inorganic and Organic Additives on Spawn Production of Milky Mushroom (Calocybe Indica)

Abstract

Milky mushroom (Calocybe indica) is one of the most important edible mushroom grown in India commonly called as “Kuduk” or “Dudhi chhata”. It was first reported from India by Purkayastha and Chandra in 1974. Two strains of Calocybe indica viz., CI-17-04 and CI-17-08 were observed for variability in terms of cultural characters, morphological characters, effect of inorganic and organic additives on spawn growth and yield performance. Fluffy growth was observed as colony appearance in both strains. The colour of colony was Milky white in CI-17-04, while in strain CI-17-08 the colour of colony was white. The average pileus breadth, stipe length and pileus weight was observed high in strain CI-17-04 5.70 cm, 8.66 cm & 25.00 g/FB. In case of spawn growth, maximum growth of both strains at different inorganic supplements was found in ferrous sulphate @ 0.50% (90.00 cm) in spawn bottle. While full growth of both strains at different organic additives was found in Rice powder @ 1% (90.00 mm) in spawn bottle. Maximum yield was recorded from CI-17-04 strain with different Organic additives casing materials (730.00 g/kg of dry substrate with 73.00% B.E.). While maximum yield (680.00 g/kg of dry substrate with 68.00% B.E) with different Inorganic and Organic additives was recorded from CI-17-04 strain.
