In the ZKI trials continued on straw which seemed to be a simple and cheap substrate. To improve yield the N-content of the straw was increased by mixing it with wheat bran, alfalfa flour and ProMycel. Enriching agents were added to the dry heat-treated straw (100 "C) at 1, 2, 3 weight per cent. All the 3 agents increased yield as related to control. The highest yield was obtained with ProMycel.application/pdfAgaricus bisporusdry heat-treatmentenrichmentfruit body yieldfolyóiratcikkOpen Accesshttps://doi.org/10.31421/IJHS/12/4/670International Journal of Horticultural Science412Int. j. hortic. sci.2676-931X
