Abstract :

Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms. The selected species for the present study, Pleurotus eous ,commonly known as pink oyster mushroom can be easily identified by the pinkish tints of the pileus and the small narrow spores. The main objective of the present study was to find out the suitability of locally available substances as substrates for the cultivation of Pleurotus eous. Seven different substances were selected and they were paddy straw, spent mushroom substrate, banana pseudostem, saw dust, coir pith compost, sugarcane bagasse and coconut leaf stalk. The biological efficiency of all the seven substrates were also analysed. Pinheads were first produced by the coir pith compost (12 days), and maximum was for saw dust. Maximum number of sporocarps were produced when paddy straw was used as the substrate. Total yield was highest for the substrate banana pseudostem followed by paddy straw. In coconut leaf stalk and sugarcane bagasse dense mycelial growth was observed, but fruiting body formation was absent. Highest biological efficiency was obtained for banana pseudostem (105.8), followed by paddy straw (92.6). In terms of yield banana pseudostem is the best substrate
