| description | The present research studies the slenderness`s answer to fractionated mineral fertilizer application in Pinus caribaea var caribaea Morelet y Golfari plantations on sandy loam soil. The fertilizer formula used was NPK (8-10-10). Seven treatments were established, differenced by fertilizer doses and application regime, alternate and continuous, and an additional witness treatment, without fertilizer. Measures of total height and normal diameter were taken, and the slenderness index was calculated for the 288 analyzed trees at 6 years, 15 years and 35 years of age. At 6 years of age, slenderness mean values were significantly higher with a single doses application of 300 g tree-1 of (NPK); at 35 years of age, the mean was statistically lower than 80 in those treatments with fertilizer doses of 600 g tree-1, 800 g tree-1 or 1000 g tree-1 respectively in alternate regime. These reached the lowest slenderness values. A linear relation between slenderness and diameter at 1,30 m was found in treatments with fertilization and a logarithmic one in the treatment without fertilization. A direct relationship between the proportion of trees with slenderness lower to 80 and the standing trees was found. Individuals with slenderness between 70 and 90 achieved higher wood volume. |

En el presente trabajo se estudia la respuesta de la esbeltez a la fertilización mineral fraccionada en plantaciones de Pinus caribaea var caribaea Morelet y Golfari sobre suelos franco-arenosos en el occidente de Cuba. La fórmula de fertilizante utilizada fue NPK (8-10-10). Se establecieron siete tratamientos diferenciados por las dosis de fertilizante y regímenes de aplicación, alterno o continuo, más un tratamiento testigo sin fertilización. Se tomaron medidas de altura total y diámetro normal y se calculó el índice de esbeltez a los 6 años, 15 años y 35 años de edad a un total de 288 árboles a los que se dio seguimiento. A los 6 años de edad, los valores medios de esbeltez fueron significativamente superiores con la aplicación de una dosis única de 300 g árbol-1 de (NPK); a los 35 años el promedio resultó estadísticamente inferior a 80 en los tratamientos a los que se aplicaron dosis de fertilizantes de 600 g árbol-1, 800 g árbol-1 o 1000 g árbol-1 en régimen alterno, los que alcanzaron los valores más bajos de esbeltez. Se encontró una relación lineal entre esbeltez y diámetro a 1,30 m en tratamientos con fertilización y relación logarítmica en el tratamiento sin fertilización. Se evidenció una relación directa entre las proporciones de árboles con esbeltez inferior a 80 y la de árboles en pie. Los individuos con esbeltez entre 70 y 90 alcanzaron los mayores volúmenes de madera.
