Abstract: The development of mushroom growing in Bulgaria coincides in time with the enlargement and mechanization of the Cooperative and State farms, i.e. with the decrease in the number of working horses. The shortage of good horse manure is aggravated because the horses are fed on forage unsuitable for mushroom growing. The Complex Experimental Station Negovan, near Sofia, has published some formulae for semi-synthetic composts for Bulgarian mushroom growers. Wheat straw, crushed corn cobs, lavender straw, and poultry manure are the basic materials. The percentage of horse manure is 0–50% of the dry matter. We try to exclude fodder from mushroom composts, except for wheat or rye straw. The paper details some of the methods used in carrying out the experiments, and gives formulae and results obtained in primitive mushroom houses, i.e. without peak heating and air conditioning.
