Effect of brewer's grain and delayed release nutrients supplementation on yield and size of Pleurotus eryngii

Two experiments were conducted to determine the effects of supplementing wood chips and cottonseed hulls with brewer’s grain and SpawnMate IISE® (SMIISE) on yield and size of two strains of P. eryngii. On oak wood chips, biological efficiency (BE) ranged from 30.7% (5% brewer’s grain supplementation; strain WC827) to 54.1% (15% brewer’s grain supplementation; strain WC515). For strain 515, increasing brewer’s grain supplementation of oak chips from 5% to 15% increased yields by 41%, whereas for strain 827 the increase was only 19%. On cottonseed hulls, yields and BEs were highest for 45% brewer’s grain supplementation. Yield increases were not linear, however. As supplementation levels for brewer’s grain increased from 15 to 30%, yields increased 39%, whereas yields only increased an additional 15% when brewer’s grain in the cottonseed hulls substrate was increased from 30 to 45%. A similar trend was observed for SMIISE supplementation; i.e., as SMIISE was increased from 3 to 6% of the dry substrate weight, yield increased 90%, whereas an increase from 6 to 9% supplementation resulted in an additional 84% increase. Thus, the magnitude of the yield response was much greater for SMIISE® than for brewer’s grain supplementation.
