| description | Some studies focus on the analysis of the effect of mineral fertilization on variables associated with tree growth in productive plantations. They mainly analyze the short-term response to fertilization. The aim of this research is therefore to analyze the long-term response to mineral fertilization, applied fractionally over the first five years of the establishment of a Pinus caribaea plantation in Viñales, Pinar del Río, Cuba. The effect on growth, in diameter and height, was examined using a randomized block design. Seven treatments were established, according to the doses and application regime of NPK, as well as a control, with no fertilizer. These variables were measured at different ages, in 288 trees over 41 years and the growth functions were estimated using a multilevel regression for the entire period and in two separate stages. The analysis of the coefficients for the obtained growing curves showed that, in the period from 2 to 41 years, the diameter and height for individual trees were, on average, superior to those of the control, in treatments of 600 g, 800 g and 1000 g of Nitrogen, Phosphorus and Potassium (NPK) per tree. Treatment with application of a single dose of 300 g of Nitrogen, Phosphorus and Potassium (NPK) tree-1 produced lower values of diameter and height than those of the control. The two-stage study demonstrated that, from 33 to 41 years, homogeneity in height was achieved among treatments, except for the treatment with 300 g of (NPK) tree-1, which presented lower heights relative to those of the control. |

Existen estudios encaminados a analizar el efecto de la fertilización mineral sobre variables dasométricas en plantaciones productivas. En su mayoría, estos analizan la respuesta de la fertilización a corto plazo. Por ello, la presente investigación estudia la respuesta de la fertilización mineral a largo plazo aplicada de forma fraccionada durante los primeros cinco años de establecida una plantación de Pinus caribaea, en el municipio Viñales, Pinar del Río, Cuba. Se investigó la respuesta al crecimiento, en diámetro y altura, a partir de un diseño de bloques al azar. Se establecieron siete tratamientos diferenciados por las dosis de NPK y regímenes de aplicación, más un tratamiento testigo sin fertilización. Se hicieron mediciones en diferentes edades a 288 árboles con seguimiento durante 41 años y se estimaron las funciones de crecimiento mediante regresión multinivel para todo el período, y en dos etapas por separado. Como promedio, en el período de 2 a 41 años, el diámetro en árboles individuales, para las aplicaciones de 600 g árbol-1 en régimen alterno, 800 g árbol-1 y 1000 g árbol-1de (NPK) fueron superiores con respecto al testigo y la altura para las aplicaciones de 800 g árbol-1 y 1000 g árbol-1 de (NPK); el tratamiento de la aplicación de una dosis única de 300 g árbol-1 de (NPK) provocó valores inferiores en diámetro y altura con respecto al testigo. El estudio en dos etapas demostró que de 33 a 41 años se logra homogeneidad en altura entre tratamientos, excepto en el de 300 g árbol-1 de (NPK) que mantiene resultados inferiores al testigo.
