The feasibility of the cultivation of a Pleurotus ostreatus strain was evaluated on
wastes of two plant species cultivated in north–west Argentina: Simmondsia chinensis and
Jatropha macrocarpa. The mycelial growth of P. ostreatus was analysed on Petri dishes
containing different proportions of both plant species wastes. The combination 4:1 of J.
macrocarpa/S. chinensis resulted as the most effective on the vegetative growth of P. ostreatus.
Subsequently it was carried out the experimental culture under controlled conditions of light,
temperature and humidity. Six treatments were done with different combinations of wheat
straw and the plant wastes. J. macrocarpa and S. chinensis combination resulted as the most
effective, with a biological efficiency of 89.7% and a production rate of 1.74%. Both
substrates are a feasible alternative for the commercial production of Pleurotus genus in
regions where no cereals crops are cultivated, like in the Province of La Rioja, Argentina.
