The Effect of Calcium Chloride and Calcium Lactate on the Yielding of Agaricus bisporus (Lange) Imbach

Abstract

Abstract The aim of the research was to assess the influence of calcium chloride and calcium lactate irrigation on the yield volume and dry matter content in two champignon strains, ie Amycel 2200 and Italspawn F59. When both strains were irrigated with calcium lactate, there was a significant decrease observed in the yield when the concentration of the solution was 0.6%. On the other hand, when calcium chloride was applied to the Italspawn F59 strain, there was a significant decrease in the yield when the concentration was as low as 0.4%, whereas the yield of the Amycel 2200 strain dropped when the concentration of calcium chloride was 0.6%. The irrigation with calcium chloride and calcium lactate had influence on the content of dry matter in the champignon carpophores. When the solutions under investigation were applied at concentrations of 0.4 and 0.6%, there was a significant increase observed in the content of dry matter in both strains.
