Impact of varied substrates on the nutritional and yield aspects of Pleurotus ostreatus (Jacaum, ex. Fr. Kummer)

Pleurotus ostreatus, commonly known as the oyster mushroom, is recognized globally for its nutritional and therapeutic properties.In this study, we aimed to investigate the nutritional and yield aspects of P. ostreatus when cultivated on different substrates.These substrates included rice straw, maize straw, wheat straw, soybean straw, chickpea straw, wood chips, sawdust, and a combination of wheat straw with full spawn inoculation.Among the substrates examined, wheat straw exhibited the highest moisture content (94.20%), surpassing all other substrates.Notably, the combination substrate of maize straw 25% with wheat straw 75% displayed the highest ash content (9.44%).Wood chips 100% exhibited highest flushes whereas Wheat straw 100% showed highest biological efficiency (%) and percentage increase in yield over control.The combination substrate yielded the lowest overall nutritional content compared to the other substrates.Remarkably, P. ostreatus cultivated on 100% rice straw exhibited the highest protein content (25.13%).
