ABSTRACT:

An investigation was carried out on the cultivation of mushroom (Pleurotus ostreatus) using corn cobs and
saw dust as the main substrates. Lignocellulosic wastes such as corn cobs and saw dust were packaged inside heat –
resistant polythene bags and pasteurized before being seeded with 7.5% w/w millet spawn of Pleurotus ostreatus and
incubated at room temperature (250C) for six weeks. Thereafter, they were exposed by incising small stripes on the
bag to give a cold shock to initiate fruiting. The result of this study showed that corn cobs had an average yield of
1,248g per flush and saw dust 526.50g per flush. Thus, indicating that saw dust gave a significantly (p<0.05) higher
yield (70%) than saw dust (30%). Mushroom cultivation in Nigeria (Developing Country) is of great importance
because it converts agricultural and industrial waste (which can pollute the environment) into edible protein; it can
serve as a means of generating employment for the Nigeria populace because it can be grown all year round; if
exported, mushrooms will be an important source of foreign exchange.
