Resumo: 	ABSTRACT Mineral nutrients have important role in plant metabolism, acting on specific vital metabolic pathways for the cell. Among the nutrients, we highlight silicon (Si), for promoting growth, improving post-harvest quality and plant productivity, as well as being able to induce resistance to pest and disease. In this sense, this study aimed to evaluate the productivity and post-harvest quality of strawberry fruits cultivars Aromas and Albion cultivated in organic system with four doses of foliar applications of SiO2 in pre-harvest (0, 5, 10, 15 g L-1), and refrigerated storage (8 days under refrigeration and 1 day at room temperature). The valuated traits were: mass loss, fruit mass, productivity, fruit firmness, soluble solids, titratable acidity, total phenolics, total anthocyanins, ascorbic acid and soluble solids titratable acidity ratio. The cultivar Aromas presented higher productivity per area (33.05 t ha-1), and more fruits per plot (479.42); however, higher average fruit mass was obtained in cultivar Albion (24.44 g), presenting better-quality fruits for fresh market. Soluble solids content, SS/TA ratio and ascorbic acid content were not influenced by silicon doses, however, refrigeration during 8 days and 1 day at room temperature provided reduction of fruit firmness, titratable acidity and, ascorbic acid content and increased soluble solids content and SS/TA ratio. Refrigeration attenuated significant reductions in anthocyanin content and, in addition, foliar silicon application promoted higher levels of anthocyanins in the fruits of both strawberry cultivars, increasing with the applied dose. The application of silicon was also efficient in maintaining fruit firmness of both cultivars.
