Strawberry quality is affected by climatic changes and production system conditions, these characteristics have an impact on commercial quality. Therefore, the objective of this study was to evaluate the effect of different production systems on the physicochemical and sensory quality of strawberry fruits, considering each system as a treatment: 1) Open field - white mulch (CAB), 2) Open field - black mulch (CAN), 3) Shadow mesh - white mulch (MAB), 4) Shadow mesh - black mulch (MAN). The evaluations were carried out at 225 days after transplantation (DDT) using five fruits (repetitions) per treatment evaluating the color, firmness, total soluble solids (SST), titratable acidity as physicochemical quality and sensory evaluation of strawberries considering their smell, sweetness, acidity, texture and overall appearance using a hedonic 9-point test, conducted by 25 untrained judges; the data was analyzed in a completely randomized experimental design, the means comparison tests were evaluated with the Fisher LSD test (p≤0.05). The systems with shade mesh and black padding presented the firmer fruits (2.43N), and intense red color (°h = 2.25) opaque (C = 33.81), while the white padded one presented the strawberries with higher values of solids Total soluble (10.82 °Brix). There were significant differences between the general appearance of the MAN (7.20) with respect to the MAB (6.16) as well as the smell in the MAN (7.28) with respect to the CAB (6.44), the global acceptance was greater than six in all treatments, which indicates a good sensory evaluation and acceptance by consumers. The use of shade mesh and black quilting is recommended for strawberry development by producers as it preserves the physicochemical quality attributes of the fruits.
