Popis: The present work aimed to evaluate the raspberry production with different dosages of the macronutrients N, P, and K in the region of South Brazil. The experiment was implanted in the Serra Gaucha region, South Brazil (Koppen classification Cfb). The raspberry variety ‘Autumn Bliss’ as evaluated, planted with spacing of 2.0 m between lines and 0.3 m between plants, irrigated by dripping. The experimental design was of randomized blocks, constituted by 7 treatments and 4 repetitions. The macronutrient dosages ranged between 0 and 300 kg/ha for N, and from 100 to 200 kg/ha for P and K. The evaluated parameters were fruit yield, soluble solids content, titratable acidity, and ratio value. The nutrient content in soil and leaves were also evaluated. The data underwent analysis of variance and the means were compared by Tukey’s range test at 5% probability. It was observed an increase in fruit yield until N dose of 200 kg/ha. There was no difference among the treatments that ranged P and K doses. The fruit quality parameters have not presented statistical difference among treatments. It was concluded that raspberry responded well to nitrogen fertilization and smaller doses of P and K supplied the plant’s needs.
