Abstract

Nutrient depletion and accumulation of toxic metabolites in compost are believed to be limiting factors and responsible for decreased yields as a mushroom crop ages. The objective of this study was to determine whether mineral nutrients limited later break yield of Agaricus bisporus in compost supplemented with additional protein-lipid rich supplements. Unsupplemented compost receiving rock phosphate or hypnum peat did not have a significant increase in later break yield. However, rock phosphate, sodium phosphate and hypnum peat added to protein-lipid rich, delayed release supplemented compost at spawning increased yield in later breaks. These results suggest the nutrient requirement satisfied by a protein-lipid rich, delayed release supplement was a prerequisite for supplementary phosphorous or hypnum peat to increase later break yields.
