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 the pH averages (%) of the compost during the cultivation phases of Agaricus bisporus. There is no statistically significant difference between averages with similar capital letters within each cultivation phase and lowercase letters within each compost (Tukey, 5%). The end of cultivation phases I and II refer to the end of composting phases and the end of phase III at the end of the production cycle (spent compost).

Mentions: The pH averages obtained in the oat-based compost did not exhibit significant differences in the cultivation phases (Figure 7). There was a significant pH reduction for the compost based on brachiaria at the end of phase II in relation to phases I and III. According to Chang and Miles (1989), that reduction possibly occurs due to the production of metabolites.
