RESUMO

The objective of this work was to evaluate the agronomic behaviour of six mixtures of casing, prepared from spent mushroom substrate (SMS), in new production cycles of Agaricus bisporus. The results obtained showed the feasibility of reuse of the SMS in new cultivation cycles when used alone by submitting it to a washing process to remove soluble salts, or mixed with other materials of low conductivity, such as Sphagnum peat or coconut fiber pith. The high values of biological efficiency recorded up to 100 kg kg-1 compost, similar to that of the controls, and the same high values observed in the dry matter content of the mushrooms harvested with some of the new casing layers prepared must be highlighted. The suggested use for SMS is an important alternative to consider, in order to replace soils and other organic substrates typically used as casing, with the added advantages of lowering the production costs and decreasing the environmental impact.
