King oyster (Pleurotus eryngii) mushroom is a palatable mushroom with high commercial potential due to relative ease of its growing technology, less cost of production and better yield potential, making it popular throughout the world. Therefore, an experiment was set up to assess the efficacy of different agro-wastes [cotton waste (CW) and fenugreek straw (FS)] on the morphology, yield and nutritional components of two strains (Pleurotus eryngii P9 strain and Pleurotus eryngii P10 strain) of Pleurotus eryngii. Studied indicators regarding time for pinhead formation, fruiting body development, biological efficiency and yield of both strains were significantly affected by different formulations of substrates. Substrates with 100 % CW exhibited maximum number of pinheads, yield and biological efficiency for both strains of king oyster as compared to other substrates alone or in mixture. This experiment indicates the possibility of Pleurotus eryngii cultivation on cotton waste and fenugreek straw in controlled conditions for enhanced growth and yield.
