  Everywhere in the world button mushroom is cultivated on heat-treated horse manure or on a compost mixture of straw, horse manure and chicken manure. In the ZKI trials continued on straw which seemed to be a simple and cheap substrate. To improve yield the N-content of the straw was increased by mixing it with wheat bran, alfalfa flour and ProMycel. Enriching agents were added to the dry heat-treated straw (100 "C) at 1, 2, 3 weight per cent. All the 3 agents increased yield as related to control. The highest yield was obtained with ProMycel.

  In this study I compared the nutritional composition of the commonly consumed fruits and vegetables with three of the most important cultivated mushrooms: white button mushroom (Agaricus bisporus LANGE/IMBACH), oyster mushroom (Pleurotus spp. JACQ. P. KUMM.) and shiitake (Lentinula edodes BERKELY/PEGLER). I compared the energy content and some mineral values (sodium, potassium, calcium, magnesium and selenium), as these play a major role in the nutritional value of mushrooms. The focus was on the vitamin B group and the vitamin D content in mushrooms, which is especially important due to the fact that fruits and vegetables do not contain this vitamin. Nowadays one of the main research and experimental topic is finding possible ways for enhancing the vitamin D content in cultivated mushrooms by UV-light. The Corvinus University of Budapest is running a project in this research area as well. Based on the data presented in this study we can say that mushrooms and therefore the cultivated mushrooms have an honourable place within the group of functional foods.
