The work was carried out on a Vertisol soil from the Cauto Valley, with the objective of evaluating the effect of different planting frames on the intensive production of living poles of the tree legume Gliricidia sepium. Six treatments were evaluated from the combination of three distances between rows (60, 120 and 180 cm) with two distances between plants (50 and 100 cm), using a 3 x 2 factorial design with four replications. A satisfactory performance was obtained in seed germination, because a population of plants per square meter was achieved two months after planting equivalent to 67,3% germinated seeds, as well as 97% average survival when the number of main shoots per hectare was compared to the number of plants per square meter. Significant interaction (P<0,01) was found among the factors in the number of plants per square meter and the best result was achieved with the 50 x 60 planting frame; this was in turn the treatment with higher total yield of poles in the third year. Stem diameter was significantly affected from the second year by the distance between rows. The lowest planting frame was concluded to provide the highest yield of living poles per hectare, although with a lower diameter than the other treatments, because of the effect of the competition among plants with the lowest distance between rows.
