The determination of green foliage production of Acacia decurrens in the first planting year, was in La Ramada farm, Quindío, located 4° 31' 41'' of latitude north and 75° 32' 41'' longitude west, an average temperature 16 °C. The age for planting was one month, in parallel rows to the slope, pruning to 1,5 m of high and the acacia's browsing was simulated by manual defoliation; The planting densities were high, medium, and low: 1664, 832 and 416 acacias/hectare, respectively; and the periods o frequency of defoliation was to 6, 9 and 12 months of planting. The variables were grams/tree of foliage production and grams/tree/day of foliage increment. All data were analyzed by ANOVA. In this trial, the planting densities were not significantly (P>0.05), however, between periods the grams/tree/day of foliage increment were significantly (P<0.05), because the better production was in the third defoliation period. Acacia foliage production is similar in the first planting year with three different densities, and the foliage production increment improves with the time.
