The Effect of Ferrum (FeSO4) on Culture Mushroom: Pleurotus ostreatus (Jacq.) Kumm.

This study was conducted on the growth, ratio of protein and cultivation of Pleurotus ostreatus on local celluosic wastes in different concentrations of the ferrous (Fe++). It was observed that Fe++ had effect on the formation and growth of thebasidiocarps. The shortest and longest period of basidiocarps formation and growth were obtained in 100 ppm and 300 ppm Fe++,respectively. The higher total amount of yield was found for 100 ppm Fe++ when compared with control, 200 and 300 ppm Fe++.Significant (P 0.05) difference was found between the control and 100 ppm Fe++, but the best yield was obtained. Mushroom protein ratio of all concentrations of ferrous (Fe++) were found to be lower than control.
