We evaluated the effect of the application of nutrients on the growth of Baccharis macrantha and Viburnum triphyllum, which were planted in a pasture located on the edge of an oak forest in Arcabuco (Boyacá, Colombia). The following treatments were established in plots: B. macrantha with nutrients, B. macrantha without nutrients, V. triphyllum with nutrients, and V. triphyllum without nutrients, each one with three repetitions. The phytosanitary condition, greatest and least diameter of the plant canopy, and height were measured for each planted individual. Analysis of planted species survival using the Kaplan-Meier method was performed and rates of relative growth (RGR) of height and coverage were calculated for all individuals, with which ANOVAs were performed to assess differences between treatments. The probability of survival of planted species decreased greatly over time. Significant differences between treatments were found for height and cover. According to field observation and statistical analysis, the application of nutrients considerably improved the growth in height and cover of B. macrantha, a result useful for the implementation of ecological restoration activities in pastures.
