This study was carried out to investigate the effect of several agro-industrial wastes and mixed substrates with rice straw (w/w) on production of ( Pleurotus ostreatus ). Mixed substrates with rice straw at rate 1:1 by weight showed higher effect on the first stage, second and third stages. Data indicated that the time for production ranged from 12 -25.5, from 22 -52.25 and from 25 -55 days respectively. When mixed substrates with rice straw the results were found within the period ranged from 11.75 -18.5, from 22.5 -28.5 and from 26.5 -32 days respectively. Mixed substrates with rice straw reduce the first stage time of oyster compare with the control substrates. Therefore, reduce pinheads and fruiting bodies formation period. The mixed substrates rice straw with waste paper (RS+WP) gave the maximum of oyster mushroom produced per 1 kg dry ~ 578.50 g and gave the maximum biological efficiency 57.85 %. Finally, mixed substrates with rice straw increase in biological efficiency of P. ostreatus over control substrates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
