Evaluation of different varying amount of spawn production on oyster mushroom

Abstract

Experiments were conducted at Department of Plant Pathology, T.D.P.G. College, Jaunpur in the two consecutive year 2010-2011 and 2011-12.Edible oyster mushroom was evaluation of different varying amount of spawn production on the yield of oyster mushroom. The experiments were laid out in completely randomized block design with six replication and five treatments viz. 60g, 80g, 100g, 120 g and 140 g spawn per bag. In every treatment one bag contain 1 kg paddy straw substrate on dry weight basis. The results are indicated Maximum yield of 402.0 g and 408.0g mushroom were harvested with 140g spawn during first and second year, respectively. It was followed by 120g, 100g, 80g and 60g spawn which gave 394.0g and 399.0g, 375.0g and 388.0g, 360.0g and 371.0g and 302.0g and 298.0g yield, respectively. It is also observed that yield of 140 and 120 g spawn, 120 and 100g spawn and 100 and 80g spawn did not differ significantly among themselves. The minimum yield of 302.0g and 298.0g were recorded from the treatment having 60g spawn.
