This study investigates the performance of different species of oyster mushrooms (Pleurotus spp.) with a focus on two key objectives: the evaluation of morphological parameters and the assessment of seasonal growth patterns across various agro-waste substrates in Eastern Uttar Pradesh. Four species Pleurotus sajor-caju, P. florida, P. djamor, and P. cornucopiaewere examined for distinct morphological traits including pileus diameter, stipe length, and overall fruit body development. Notable interspecies variation was observed; for instance, P. cornucopiae showed the largest pileus, while P. florida displayed the longest stipe, highlighting species-specific growth profiles critical for commercial identification and yield optimization.

In addition, seasonal influence on mushroom productivity was evaluated using wheat straw and paddy straw as substrates. Findings revealed that all species exhibited enhanced yields during the winter season, particularly on wheat straw, suggesting a favorable climatic synergy and substrate compatibility. P. sajor-caju and P. florida consistently outperformed other species under these conditions. The study concludes that both morphological traits and seasonal factors significantly impact the cultivation outcomes of Pleurotus species. These insights are instrumental for selecting suitable species-substrate-season combinations to maximize production, quality, and profitability in mushroom farming, especially in agro-climatic regions similar to Eastern Uttar Pradesh.
