| Abstract | ||||
| Agricultural wastes that were used in this research rice straw, sugarcane bagasse and cotton wastes. Also, five species of the genus Pleurotus (P. ostreatus, P. columpinus, P.pulmonarius, P. sajor-cajue and P. floridanus) were evaluated with the substrate mixture to ascertain their contribution to the biological efficiency (BE). Total yield and mean number of fruit body per flush were studied the experiment was set up as a complete randomized design with three replicates The period of spawn run was constant 21 days for all oyster mushroom species tested. The mycelial growth on liquid media exhibited the highest values at sugarcane bagasse, followed by rice straw, whilst the cotton wastes produced the lowest mycelial dry weight. On solid agricultural wastes media, rice straw produced the highest total yield for P. columpains and P. sajor-cajue where the BE was the highest recording 64.4% and total yield 225.4gm. On the other hand, sugarcane bagasse produced the highest total yield for P. columpains 215.8 gm and biological efficiency 61.6% whilst cotton wastes produced the highest total fruiting body yield for P. flouridans 215 gm and biological efficiency 61.4%. The first flush gave the highest mean number of fruit body and total fruit body weight, the third flush gave the lowest mean number of both traits and the second flush produced the second highest mean number of fruit body and total yield. | ||||
