de Andrade MC, de Jesus JP, Vieira FR, Viana SR, Spoto MH, de Almeida Minhoni MT - Braz. J. Microbiol. (2014)

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.

f1-bmj-44-4-1139: Comparison of humidity averages (%) of the compost during the cultivation phases of Agaricus bisporus.

Mentions: The average humidity content of the compost exhibited progressive reduction with time, with the highest average being observed at the end of phase I (75.3%), followed by phases II and II (69.3 and 63.7%, respectively) (Figure 1). This reduction occurred due to the different management phases during the preparation of the compost (Table 2), when straws are initially much more irrigated in pre-composting than in the subsequent phases. These results are satisfactory within a standard composting, where the humidity content of approximately 70% is recommended at the end of phase II of composting (Andrade et al., 2008).
