The objective of the present work was to evaluate the effects of different doses of NPK on the dynamics of floristic composition and quality in the native field in the Dom Pedrito, RS. The experimental area consisted of four levels of fertilization appliedto the haul, being: 0 (control), 150, 300 and 450 kg/ha, Floristic surveys, dead biomass contribution,vegetation cover, height and bromatological analyzes were carried out in the area. There was an increase in height as the doses of NPK were increased. In the bromatological analysis, the percentage of crude protein increased in the treatments with fertilization. The percentage of NDF had a reduction of the fibrous material of the pasture, presenting in the treatment0 (71.74%) the highest content and a reduction in the 450 (48.45%). Among the floristic, the fall period obtained more species as well as families.
