SummaryIn this study, the agronomic viability of Pleurotus ostreatus (Jacq.: Fr.) P. Kumm. was studied by reusing spent substrates that were previously used for crops of this mushroom. After the physical and chemical characterization of the substrates, we evaluated the quantitative production parameters for one growing season. The experiment used wheat straw (WS) and spent Pleurotus substrate (SPS) as a base material to generate prepared substrates that could be reutilized for mushroom production. These base substrates were supplemented with wheat bran (WB) (two doses, 300 and 600 g/6 kg) and the commercial supplement Calprozime® (120 g/6 kg). We obtained a biological efficiency (BE) between 50 and 63%, a high quantity of mushrooms (between 26 and 39 mushrooms/bag) and an excellent unit weight of the fruiting bodies (between 24.34 and 39.54 g) with the substrates supplemented with a 120 g/6 kg dose of Calprozime®.
