74. Impact of different lignocellulose substrates on growth and yield of oyster mushroom (Pleurotus ostreatus)

Abstract

Mushrooms are increasingly becoming an important component of diets worldwide and it is of paramount importance to choose appropriate substrates in a given place to grow them. The experiment was conducted at University of the Poonch Rawalakot-Pakistan. The present study was focused to evaluate the growth and yield of Pleurotus ostreatus cultivar on different lignocellulose substrates. Four types of lignocellulose substrate namely (paddy straw, wheat straw, sawdust of Chir and sawdust of Kail and their combinations) were arranged in a completely randomized design (CRD) with three replications.  The data was recorded on days to completion of spawn running, days for appearance of pinheads, number of pinheads, no. of fruiting bodies, days to maturation, mushroom yield (g), biological efficiency (%) and protein content (%). Optimal temperature (25^oC) and high relative humidity were provided for oyster growth. No. of pinheads (21.33), no. of fruiting bodies (15.33), days to maturation (11.66), mushroom yield 232g and biological efficiency (BE) 38.66  (%) were achieved on wheat straw.  Therefore, wheat straw is recommended for Pleurotus ostreatus cultivation. As conclusion, this study was put the baseline information to cultivate mushrooms other edible mushrooms on this substrate used for cultivation.
