Assessment of different casing materials for use as peat alternatives in mushroom cultivation. Evaluation of quantitative and qualitative production parameters

Abstract

In this work, various casing materials (composted pine bark, coconut fibre pith and wood fibre) have been evaluated as alternative to peat (sphagnum blonde peat and black peat) for the cultivation of mushroom. For this, both quantitative (number of mushrooms, yield, unit weight, biological efficiency and earliness) and qualitative (diameter of the sporophore, colour, dry matter, texture, proteins, soluble solids, ash and pH) production parameters were evaluated. The results obtained for the number of mushrooms, unit weight, total production, biological efficiency, diameter of the sporophore, colour, dry matter, protein, soluble solid and ash content, and pH, differed among the three mushroom strains considered. The greatest proportion of harvested mushrooms were of medium size for all strains and casing layers considered. No significant differences were observed in colour and texture among the casing types.
