| Abstract | ||
| Three experiments were conducted in the project of fungi-Medicinal and Aromatic Plants Research Unit-College of Agric./Univ.of Baghdad from 1/11/2010 to15/6/2011. The spawn of white strain of oyster mushroom (Pleurotus ostreatus (Jacq. Fr.) was produced using tissue culture. Three different sources of nitrogen was added to the plastic bag after incubation stage at the following concentrations: Urea concentrations 0 or 500 or 1000 or 2000 or 4000 ppm or poly amino acids solution or water extract of faba bean dry seeds each concentrations following 0 or 0.5% or 1% or 2% or4%. The results showed that the fresh and dry yield , the biological efficiency and dray matter percentage and protein percentage significantly increased with using three different sources of nitrogen than control treatment. Use of 1000 ppm increased fresh yield to 774.0 g/kg of substrate and to 914.0g/kg when used 2% poly amino acids solution and to1020.0 g/kg of substrate when used 2% water extract of faba bean dry seeds compared with used water (control treatment) 406.4g/kg of substrate. The concentration of different sources of nitrogen increased of the biological efficiency and the percentage of the protein significantly in the fruiting bodies of oyster mushroom. Treatments with 2%, 4% urea and 4% water extract of faba bean dry seeds had no significant effects on the percentage of decay after storage. | ||
