edible mushrooms are appreciated for their taste and nutritional qualities. lignocellulosic wastes are excellent substrates for their production and mycelium propagation (inoculum or spawn). the aim of this work was to evaluate three agricultural residues: rice straw, corncob and peanut husk to produce pleurotus pulmonarius ccb19 spawn. the spawns were inoculated in bags containing 150 g of a mixture of wheat bran:corn husk:peanut husk (5:2:3). the fruit bodies were harvested from the substrate and biological efficiencies, yield and size were calculated. the rice straw spawn produced the highest body fruit, showing a biological efficiency of 43%. however, the least time for fructification was with corncob powder spawn. larger mushrooms were obtained when rice straw was used as spawn. the means of the eb were 28 and 23% in corn cob and peanut husk, respectively.
