| description | Dominant height curves and site index were defined and validated, which allowed inferring the qualities of the forest site of the white carob tree and characterizing the most influential site factors on the growth of the species in the irrigated area in the province of Santiago del Estero, Argentina. Based on the Gompertz model, an average function was adjusted for the dominant heightage by the guide curve method, from which the family of curves was derived by the principle of constant proportionality. The trend shows that the growth in height culminates close to 20 years. A first approximation in the estimation of the productive capacity of the sites for Prosopis alba Griseb. is expressed from the family of anamorphic curves at the base age of 15 years that describe three qualities: I (high), II (medium) and III (low). In relation to site factors, the chemical properties evaluated in soils were decisive in growth, negatively conditioned by electrical conductivity and other characteristic parameters of salinity conditions. The validation process determined an error between 5 and 10 %. |

Se definieron y validaron curvas de altura dominante e índice de sitio que permitieron inferir las calidades del sitio forestal del algarrobo blanco y caracterizar los factores del sitio que tengan mayor influencia en el crecimiento de la especie en el área de riego de la provincia de Santiago del Estero, Argentina. A partir del modelo Gompertz se ajustó una función promedio para la altura dominante-edad mediante el método de la curva guía, de la cual se derivó la familia de curvas por el principio de proporcionalidad constante. La tendencia muestra que el crecimiento en altura culmina próximo a los 20 años. Una primera aproximación en la estimación de la capacidad productiva de los sitios para Prosopis alba Griseb. se expresa a partir de la familia de curvas anamórficas a la edad base de 15 años que describen tres calidades: I (buena), II (regular) y III (mala). Con relación a los factores del sitio, las propiedades químicas evaluadas en suelos fueron determinantes en el crecimiento, condicionado negativamente por la conductividad eléctrica y demás parámetros característicos de las condiciones de salinidad. El proceso de validación determinó un error entre 5 y 10 %.
