Three compost formulations, consisting of two varieties of Cynodom dactylon (L.) Pers. (Coast-cross and Tyfton) and oat (Avena sativa) straw were tested for the cultivation of A. bisporus strains ABI-01/01, ABI-04/02, ABI-05/03, and ABI-06/04. A completely randomized experimental design in a factorial scheme was adopted, with 12 treatments (4 A. bisporus strains × 3 types of compost) and 8 replicates. Each experimental unit corresponded to one box containing 12 – 12.5 kg fresh wet compost. The data were submitted to analysis of variance and the means were compared by Tukey test. According to the results, productivity of mushrooms was influenced by strain and/or compost type. It was also verified that crude protein, ash, and crude fiber contents in the mushroom varied with A. bisporus strain and straw used in the formulation of the compost.
