Abstract

 

A study was performed to correlate the stipe length, pileus width and stipe girth of oyster mushroom (Pleurotus ostreatus) grown in different farm substrates. The experiment was laid out in a completely randomized design with eight treatments and four replications. The farm substrates (treatments) were composed of mixtures of different types of agricultural wastes with lime and water as additives to each substrate. Also single agricultural waste supplemented with lime and water was also used to prepare some farm substrates. Higher mean values of stipe length, pileus width and stipe girth were obtained from mushrooms grown in the substrates composed of two different types of agricultural wastes while lower values were obtained from those grown in the substrate composed of single agricultural waste. Highest coefficient of determination was obtained from the correlation between biological efficiency and pileus width. The changes in the stipe length, pileus width and stipe girth of the mushrooms grown in the different farm substrates depended on the type of agricultural wastes, single or mixtures of two different agricultural wastes used in preparing the farm substrates. Biological efficiency was highest (97.9%) in the substrate made from maize cob and palm kernel cake. Farm substrates that were composed of two different agricultural wastes were recommended. The use of single agricultural waste for farm substrate production is not encouraged.
