Abstract:
Oyster mushroom (Pleurotus spp.) is fungal fruiting body. There are several oyster mushroom varieties available. Some of the varieties were commercially cultivating in Tamil Nadu. The seeding material for mushroom is spawn. The spawn will give good yield based on the climatic condition especially temperature and relative humidity (Bugarski, D 2000). A study was undertaken for identifying effect of temperature and relative humidity on oyster spawn production exclusive for Trichtrappalli district. The isolation is made from mushroom. The mushroom isolation was done for pure culturing of mushroom. These isolates were cultured in PDA medium. Sorghum and paddy seeds were used for spawn production. The spawn production mainly depends upon temperature and relative humidity, however the temperature and relative humidity of December and January months are more favorable for spawn growth compared to March and April. The high yield was recorded in December and January compared to February while during the project period. The results showed that temperature and relative humidity are the main climatic factors that alter the spawn growth.
