Effect of Abiotic Factors on Oyster Mushroom Production (Pleurotus Species)

Abstract

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