The influence of flushes on some constituents of mushrooms (Agaricus bisporus) cultivated on different composts

Abstract

The effect of two different composts: horse manure and broiler chicken manure and the influence of flushes during the growing cycle on some chemical components contained in the mushroom (<i>Agaricus bisporus</i>) was studied. The strain Somycel 11 was analyzed. The following determinations were made: dry matter, total nitrogen and crude protein, nitrates, nitrites and amino acids composition. It has been noted that the crude protein from. combined flushes III to VI of mushrooms cultivated on horse manure was about 24% higher than in those grown on broiler chicken manure. Some changes in amino acids composition, especially lysine, histidine, arginine, aspartic acid, serine, methionine, glutamic acid and alanine were observed, depending on the size of the fruit-body, flushes and type of compost.
