IMPACT OF SAWDUST USING VARIOUS WOODS FOR EFFECTIVE CULTIVATION OF OYSTER MUSHROOM

Abstract

Sawdust of different woods which included Kikar,Mango,Simbal and Kail used as substrates were investigated for cultivation of Oyster mushroom. The maximum linear mycelial growth after 5, 10 and 15 days respectively were observed on Kikar (Acacia nilotica). The minimum linear mycelial growth after 5, 10 and 15 days respectively were observed on kail (Pinus wallichiana).Pleurotus species artificially cultivated worldwide especially in South East Asia, India, Europe and Africa.Oyster mushroom showed relatively more linear mycelial growth in control treatment of cotton waste as compared to other substrates.The data regarding 25%, 50%, 75%, 100% of spawn running of Pleurotus ostreatus,the significantly effective substrate was sawdust of Kikar followed by the other substrates.It was observed that Pleurotus ostreatus gave the maximum yield in the first flush followed by second and third flush.The maximum yield was obtained on Kikar sawdust 282.2gm followed by Mango sawdust 257.7gm, mixed sawdust 233gm, Simbal sawdust 216.5gm and Kail 200.5gm.Oyster mushroom showed relatively more yield on control treatment of cotton waste as compared to other substrates. The maximum biological efficiency was obtained in kikar sawdust which was 70.56 %. The lowest biological efficiency was obtained in kail sawdust which was 50.12 %. Among all substrates, sawdust of Kikar proved the best substrates for the effective cultivation of Oyster mushroom.
