Abstract

An experiment was established in Paranaguá, located in the costal region of the State of Paraná, in southern Brasil, in order to evaluate commercial yield of hearth-of-palm produced by Peach-Palm (Bactris gasipaes) established under the following four different initial spacings: T1 2x1m (5000 seedlings/ha); T2 3x1m (3333 seedlings/ha); T3 1,5x1x1m (8000 seedlings/ha); and T4 2x1x1m (6666 seedlings/ha). Mineral fertilizers (NPK) were applied at planting as well as subsequently. Results obtained by the time of the first cutting, 24 months after planting, allowed the following conclusions: a) the quantities of the NPK fertilizer used promoted changes in the chemical soil characteristics; b) commercial yield of hearth-of-palm improved as a function of stand density; and c) each kg of hearth-of-palm yielded 3.3 pots of the final commercial product.
