In this paper, the agronomic viability of Pleurotus ostreatus (Jacq.) P. Kumm. is studied by reusing the spent substrates previously used in crops of the same mushrooms. To this substrates are applied commercial nutritional supplements (Calprozime®, Champfood® and Promycel®), to research their potential use as additives together with wheat straw (WS), calcium sulphate and calcium carbonate at different doses. After the physical and chemical characterization of the substrates, we evaluated the qualitative production parameters in one flush. The mixture of wheat straw (WS) (3,000 g) and spent Pleurotus substrate (SPS) (3,000 g) supplemented with 120 g of each of the commercial supplements (Promycel®, and Calprozime® Champfood®) are substrates that promote red-green (a*) and yellow-blue (b*) chromaticity in harvested mushrooms. This manuscript presents the results obtained in an experiment where different supplements were used to enrich substrates composed of wheat straw and spent substrate. Qualitative features of Pleurotus ostreatus mushrooms were evaluated.
