Aiming at verifying the quality of the fruits of strawberries, Fragaria ananassa cv. Camarosa short day, under different kinds of mulching and levels of shading, this experiment was conducted at the Experimental Farm of the State University of the West of Paraná (Unioeste), Campus of Marechal Candido Rondon, Paraná, Brazil. The seedlings were placed in a 30 x 30 cm within three rows in bed of 1.0 m wide, receiving irrigation and cultivation of fertilization and pest management, according to the culture demand. After the fixation of the seedlings, mulch was inserted over the flower beds, and the screen with 50% of shade to 50 cm tall. The experimental design was randomized blocks, factorial double, 4 x 2 (black polyethylene 200 μ m; Tifton grass hay, non-textured fabric, and sifted charcoal x open field and 50% shading), containing three replicates with 12 plants for each repetition. For the open field condition, we observed statistic differences in the percentage of healthy fruit, fruit biomass and the number of fruits/plant, besides the higher levels of soluble solids, favoring the quality of the strawberries fruits. The Tifton mulching mower can be considered as an important coverage construction, since it can be naturally recycled providing plant nutrients and organic material to the soil, instead of generating waste, as the plastic commonly does.
