Bottom Line: The experimental design was a 2 × 3 factorial scheme (composts × strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost).The chemical characterization of the compost (humidity, organic matter, carbon, nitrogen, pH, raw protein, ethereal extract, fibers, ash, cellulose, hemicellulose, and lignin) before and after the cultivation of A. bisporus and the production (basidiomata mass, productivity, and biological efficiency) were evaluated.Data were submitted to variance analysis, and averages were compared by means of the Tukey's test.

ABSTRACT
Two compost formulations based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) were tested for the cultivation of three Agaricus bisporus strains (ABI-07/06, ABI-05/03, and PB-1). The experimental design was a 2 × 3 factorial scheme (composts × strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost). The chemical characterization of the compost (humidity, organic matter, carbon, nitrogen, pH, raw protein, ethereal extract, fibers, ash, cellulose, hemicellulose, and lignin) before and after the cultivation of A. bisporus and the production (basidiomata mass, productivity, and biological efficiency) were evaluated. Data were submitted to variance analysis, and averages were compared by means of the Tukey's test. According to the results obtained, the chemical and production characteristics showed that the best performances for the cultivation of A. bisporus were presented by the compost based on oat and the strain ABI-07/06.

Comparison of neutral detergent fiber averages present in the cultivation composts of Agaricus bisporus, in function of the period (before and after cultivation) and the types of composts. There is a statistically significant difference between averages followed by different capital letters within each type of compost and lowercase letters within each period (Tukey, 5%).

f11-bmj-44-4-1139: Comparison of neutral detergent fiber averages present in the cultivation composts of Agaricus bisporus, in function of the period (before and after cultivation) and the types of composts. There is a statistically significant difference between averages followed by different capital letters within each type of compost and lowercase letters within each period (Tukey, 5%).

Mentions: We verified a reduction in NDF and ADF contents of the final compost in relation to the initial compost during the cultivation period (Figures 11 and 12). According to Castro (2003), reductions in NDF and ADF contents in the final (residual) substrate are expected, because fungi have an enzymatic ability to degrade components of the cellular wall that are present in the raw material of vegetable origin. These results agree with several other works that also reported reductions in NDF and ADF fractions in substrates treated by fungi (Belewu and Belewu, 2005; Gonçalves et al., 2010).
