Abstract
This study was conducted at the mushroom Production unit, Dept.of Hort. Univ.of Baghdad in the first of Nov. / 2010.Oyster mushroom P.ostreatus spawn was imported from Jordan . Mushroom spawn at arte of 5% added to sterilized and moist wheat straw and incubated at 25± 2C°, transferred to propagation room after one month at 25 ± 2C° at, RH 80-90 % and light intensity 400 Lux. Two kind of mineral fertilizers were, King Life and Nap nutria.King Life as powder, used at the following concentrations, 0,10,20,40 g/l .The second fertilizer was used at(The concentrations,0,10,20,40ml/l. ) The organic fertilizers Pow humus and Liq humus were used at following concentrations , 0,1,10,20 ml/l .the fertilizer was injected inside each bag. with 50 ml of each concentration using plastic syringe at the end of incubation period .The results showed that there were no significant effects of the mineral fertilizers on the yield and the biological efficiency of mushroom .While the organic fertilizers increased yield and biological efficiency at 20 ml/l to 864g/kg and 135.85 g/kg of substrate and 86.43% , respectively .when Pow humus was used . While Liq humus gave 639.77 gm/kg and 101.90 gm/kg of substrate and 63.90 %, respectively.It was concluded from these results that oyster mushroom has asignificant response to organic fertilizer.Thus we recommend using organic fertilizers when producing this species of mushroom .
