Abstract
This study was carried out to find a local natural media for growth of two strains of edible mushroom which were recorded the first time in
Iraq-Missan governorate and belonging to the genus oyster mushroom Pleurotus ostreatus and brown Agaricus bisporus. Different natural
media was used for this purpose involved two types of agricultural wastes of apple peel and banana peels s and potato peels, maize peels and
date seeds in addition to the leaves of sugar plant Stevia rebaudiana the second type included animal wastes ,feather of chicken and wool of
sheep and concentrations ranging from 10-40 g /L .Also studied The effect of some physical factors and conditions temperatures and pH on
the growth rates of two species Pleurotus ostreatus and Agaricus bisporus. The results showed that the mean percentages of chicken feathers
and sheep wool achieved the best growth rates for both species of edible mushrooms, the growth rate of two species of edible mushroom on
feather and wool (1.20, 1.18) cm / day, (1.18, 1.17) cm / day then followed the leaves of Stevia rebaudiana (1.00, 0.94) cm/day respectively,
and the rest of the other medium compared to the medium of Potato Dextrose Agar (PDA).The best concentration for the preparation of
these media was 10 and 20 g / L compared with 30 and 40 g / L. The best pH value that could be used to growth of Pleurotus ostreatus and
brown Agaricus bisporus were 6.5which achieved the highest growth rates in all natural culture media for both species of edible mushrooms,
and the best temperature was 30 ºC regardless of the type of medium.
