Physiologic response of Agaricus subrufescens using different casing materials and practices applied in the cultivation of Agaricus bisporus

Abstract

Casing materials and practices used in the cultivation of Agaricus bisporus were evaluated in the cultivation of Agaricus subrufescens, using the best techniques for optimization of production, including the possibility of re-casing of the compost for the production of a second crop of mushroom. Casing based on peat moss, loam soil or coir was compared to casing material mixed with or without spawn-run compost. Based on the results, we conclude that the casing layer used in the cultivation of A. subrufescens should not necessarily be the same as that used in the cultivation of A. bisporus. For the tested strain cultivated with loam soil as casing layer, the ruffling technique is highly superior to CACing and should be pursued in further research. The re-casing of compost in new cycles showed good results suggesting that the currently used compost could be improved.
