Potential of organic residues in producing oyster mushroom, Pleurotus ostreatus Fr. (Polyporaceae).

Abstract

Low mushroom yields are observed when non-supplemented substrates are used for production. The experiments were carried out to evaluate potential benefits of organic supplements in cotton residues, maize stover and wheat straw substrates used for cultivation of oyster mushroom. Mixed formulations at various doses of 0, 4, 8 and 14 % sunflower seed cake supplement levels were autoclaved before inoculation with P. ostreatus spawn. Duration of developmental stages, mycelium vigour and yield of oyster mushroom on substrates formulations were evaluated. The mycelium vigour significantly increased (P International Journal of Biological & Chemical Sciences Vol. 1 (2) 2007: pp. 108-120
