The influence of compost on carbohydrates and minerals content in the mushrooms (Agaricus bisporus)

Abstract

A study of the effect of different composts: horse manure and broiler chicken manure and the influence of flushes during the growing cycle on the carbohydrates and mineral composition of mushrooms (<i>Agaricus bisporus</i>) was carried out. In this study the strain Somycel 11 was used. It was found that mannitol, glucose and fructose contents in mushrooms growing on broiler chicken manure were significantly higher than on horse manure. Noticeable differences of macro- and microelement contents were observed, depending on the size of the fruit-body, flushes and type of compost. Phosphorus content in mushroom tissue of the first three flushes growing on horse manure was 2.7 times higher than in those from broiler chicken manure. Boron level in mushrooms in all flushes growing on broiler chicken manure was four times higher as compared with that on horse manure.
