Mineral composition of substrates based on banana waste during the Pleurotus ostreatus cultivation

The objective of this study was to evaluate the mineral composition (macro e micronutrients) of the substrates [initial and residual (postharvest)] based on different combinations of waste (leaf, pseudo-stem and pseudo-stem + leaf) and banana cultivars - Musa spp. (Thap Maeo, Prata Anã, Pelipita and Caipira) during 49 days for the cultivation of POS 09/100 strain of P. ostreatus. It was verified that all of the substrates based on different combinations of waste and banana cultivars presented satisfactory amounts of nutrients for the cultivation of P. ostreatus, both in the initial phase of cultivation and in the end.
