Abstract

 In this study, the growth rate and saprophytic ability of UREA-treated WHEAT STRAW were studied. In the first experiment the species of Pleurotus ostreatus (2021)and cross between Pleurotus ostreatus and Pleurotus sajorcaju (2030), Pleurotus hybrid Iranian (2041), Pleurotus of wild (2060), on UREA treated WHEAT STRAW (0.0, 1.25, 2.5%) were cultivated. in the second experiment the effects of cultivation of fungi on chemical composition and digestibility of WHEAT STRAW, treated with3% UREA were investigated. The best growth rate and favorite mycellium extension of fungi were seen in the 2060 and 2021 species respectively. UREA supplementation had significant negative effects (p<0.05) on growth rate and saprophytic ability of all species (except 2060 sp). Cultivation of fungi decreased the organic matter and cell wall contents of WHEAT STRAW among of cell wall contents (cellulose, hemicellulose, lignin) the highest reduction was seen in hemicelluloses content (p<0.05). The dry matter and organic matter digestibility of treated WHEAT STRAW increased (p<0.05) following fungies cultivation. The results of this study showed that with higher growth rate are more suitable and effective than the others.
