description | The main objective of this work was to develop a height estimation method of Prosopis alba based on the diameter at breast height (DBH) of populations with superior characteristics selected through a progeny trial located in the INTA Experimental Agricultural Station, Province of Santiago del Estero, Argentina. The progeny trial was established in 2008 and consists of 3,671 individuals (202 families). The registered variables were DBH and total height (TH) of 123 individuals, taken at random from the three blocks that make up the trial. Linear regressions were performed to develop the model that best fits height estimation with all the sampled individuals (AI model) and, also using the data of 7 individuals - the three trees of greater diameter, the three of smaller diameter and an individual of intermediate diameter-, called the reduced height estimation model (RHEM model). AI model and RHEM model were satisfactory to estimate height of the trees based on their DBH in the trial of progenies in Santiago del Estero. However, the RHEM model offers an important saving of time and effort, simplifying the field activity. |

El objetivo del trabajo fue desarrollar un método de estimación de la altura de los árboles en función de su diámetro a la altura de pecho (DAP) de poblaciones selectas de Prosopis alba seleccionadas por características superiores, en un ensayo de progenie ubicado en la Estación Experimental Agropecuaria de la provincia de Santiago del Estero. El ensayo de progenie fue establecido en el año 2008 y está conformado por 3671 individuos (202 familias). Las variables registradas fueron el DAP y altura total de 123 individuos, tomados al azar de los tres bloques que conforman el ensayo. Se realizaron regresiones lineales para determinar el modelo que mejor ajusta a la determinación de la altura con todos los ejemplares muestreados (modelo TI) y, también utilizando los datos de siete ejemplares –los tres árboles de mayor diámetro, los tres de menor diámetro y un individuo de diámetro intermedio–, denominado modelo de estimación reducido de altura (modelo MERA). Tanto el modelo TI como el MERA fueron satisfactorios para estimar la altura en función del DAP. Sin embargo, el modelo MERA ofrece un importante ahorro de tiempo y esfuerzo en las mediciones.
