Studies on Different Chemicals on Spawn and Casing for Production of Milky Mushroom (Calocybe Indica)

Abstract

Milky mushroom (Calocybe indica) is a tropical edible mushroom of Indian origin and can be cultivated in high temperature and humidity areas. It is one of the important mushroom commonly called as “Kuduk” but popularly known as “Dudhichhata” or white milky mushroom. The present investigation was carried out on “Studies on different chemicals on spawn and casing for production of Milky mushroom (Calocybe indica)” during cropping period in 2017-18. The experiment on the effect of different inorganic supplements on maximum radial growth was observed at 11th day observations in ferrous sulphate @ 1% and Magnesium sulphate @ 1%. The minimum growth in control. The effect on dry matter growth showed that maximum dry matter was recorded at Magnesium sulphate @ 1 % followed by Magnesium sulphate @ 0.5%. The minimum weight of dried mycelium was observed in Potassium sulphate 1%. The maximum growth of mycelium in glucose @ 1.5% and sucrose @ 1.5% followed by glucose @ 1%, the minimum growth of mycelium in lactose @ 1.5%. Dry matter growth was grown in sugar solution with 50 ml potato extract broth. Maximum dry mycelial weight was found in glucose @ 1.5%. Which are significantly superior as compare to control. The minimum dry matter in lactose @ 1%. The effect of different inorganic supplements on Maximum spawn growth was observed at 20 day observations in ferrous sulphate @ 1% followed by Magnesium sulphate @ 1%and found minimum in control. The spawn were grown in different sugars on maximum spawn growth at 20 days of observation was found in glucose @ 1.5% and sucrose @ 1.5%, followed by glucose @ 1%. The minimum spawn growth in lactose @ 1%.The different combinations of calcium carbonate and calcium sulphate in different ratio increase the spawn growth on maximum spawn growth was observed in CaCO3 (0.4 %) + CaSO4 (1.3 %) followed by CaCO3 (0.3 %) + CaSO4 (1.3 %) ratio on 20 days. minimum growth was observed in at CaCO3 (0.5 %) + CaSO4 (1.4 %). Regarding yield the experiment was conducted to find out the chemical supplements. The results indicated that Minimum days were observed for spawn run in supplemented with magnesium sulphate @ 0.5%, which were significantly superior to without supplemented treatment. Maximum numbers of pinhead initiation were recorded in treatment supplemented with magnesium sulphate @ 0.5%. Maximum numbers of fruiting bodies were harvested in magnesium sulphate @ 0.5% and manganese sulphate @ 0.5%. Maximum yield was harvested significantly well in magnesium sulphate @ 0.5% treatment followed by manganese sulphate @ 0.5% as compared to control. However, maximum average weight per fruit body was recorded significantly on magnesium sulphate @ 0.5% supplemented minimum average weight per fruit body was recorded in control.
