• Abstract:

  The species Rubus rosifolius Smith, known as Red Mulberry, Wild Strawberry or Wild Strawberry, is a plant native to Brazil. Amora occurs spontaneously in the Alto Vale do Itajaí. It can be used for fresh consumption and in the preparation of jellies, sweets, compotes and wine. The project aims to evaluate the agronomic potential of the species, observing the phenology, adaptability in an area cultivated under different fertilizations and evaluating the quality parameters of the fruits, also verifying the phytotherapeutic potential. The experiment was carried out in an experimental orchard with root cuttings obtained in the Alto Vale region, in Ituporanga-SC and at the headquarters of ``Instituto Federal Catarinense``.
  – Campus Rio do Sul. The cultural treatments were the same for all the plants in the orchard, such as mowing and pruning, only differentiating the fertilization treatments. Fertilization treatments consisted of five doses of N (0.0, 7.5, 15.0, 22.5 and 30.0g per plant), applied in maintenance fertilization. The doses, 0.0, 7.5, 15.0, 22.5 and 30.0 g correspond to 0.50, 100, 150 and 200% of the recommended dose (Fertilization and liming manual for the states of Rio Grande do Sul and Santa Catarina, 2004). The maintenance doses of N were divided into three applications: at the beginning of sprouting, with the second and third applications being carried out 15 and 30 days after the first. Maintenance phosphate and potassium fertilizers were carried out in a single application, at the beginning of sprouting. There was no statistical difference between the data, one hypothesis for this is that because they are wild plants, they are able to develop well without the need for the use of additional nitrogen fertilizer.
