THE EFFECTS OF COMPOST ADDED BACTERIA, ORGANIC FERTILIZER AND THEIR MIXTURES ON YIELD AND QUALITY OF MUSHROOM (AGARICUS BISPORUS)

The effects of compost added bacteria, organic fertilizer and their mixtures on yield and quality in Agaricus bisporus were investigated. Standard (ST, Control), ST + B (Bacterial strains; Bacillus subtilis and Bacillus megatorium), ST + OF (Organic fertilizer) and ST + OF + B media were used for mushroom growing. According to the results, while the highest total yield (1167.28 g/8 kg bag, 1084.19 g/8 kg bag) were obtained from ST + OF and ST OF + B media, respectively, the lowest yield (923.82 g/8kg bag) was determined in ST media. The highest value of mushroom weight, cap diameter, length and weight, mushroom stem diameter and weight were reported in ST + OF + B media. There were no statistical differences among the media investigated in terms of mushroom stem length, dry matter (%), pH, ash amount, N and protein in dry matter. Mineral matter contents were different based on the media. While the highest protein ratio (5.63 mg/g) in fresh mushroom was determined in ST + OF media, the lowest (5.37 mg/g) was in ST.
