In this study we analyzed the effects of compost supplementation for Agaricus subrufescens mushroom production. The compost was inoculated with two different strains and supplemented with 0%, 2% and 4% of the commercial product Sylvan with the aim of increasing productivity. On the basis of our findings, we can conclude that both the supplementation and the strain directly affect A. subrufescens productivity, highlighting the importance of the appropriate supplementation of composts for different types of spawn.
