The effect of some nutrients added to synthetic compost with wheat straw, on mycelium growth, yield and early ripe of Agaricus bitorquis (Quél.) Sacc. were investigated. The compost was prepared by fermentation and chemical disinfection methods. Corn flour, wheat flour, hen grain, soybean meal and sunflower seed hulls were used as additional nutrients. The experiments were made at the temperatüre 20-22°C and 80-90% relative humidity in the yield rooms. The shortest mycelium growth period (average 14 days) were determined in containing 350 g/10 kg and 450 g/10 kg sunflower seed hulls. The maximum production were taken in the sacks of added 450 g/10 kg hen grain (average 2381.7 g) and 450 g/10 kg sunflower seed hulls (average 2308.3 g). The and of experiments, it was determined that the growth period of Agaricus bitorquis (Quél.) Sacc. mycelium was shortened and amount of yield also was increased.
