ResumoMesquites make up an important source of income to the peoples within the South American arid and semiarid areas. Black Mesquite Prosopis nigra (Griseb) Hieron, belongs to the Mimosaceae family and grows in the central and north parts of Argentina. In addition to its wood, its sheaths are used for the production of human food and forage while its bark is used as dyes, tanners and for medical purposes. Presently, together with the aforementioned uses, it becomes relevant the contribution this species makes to the environmental enhancement, and to soil and biodiversity conservation due to its ability for fixing carbon. The tree heightdiameter relationship is of marked interest or usefulness since both volume estimations and mass structure organization can be derived out of it. It is worthy of note that measuring only diameters instead of heights of every tree saves much labor. Total height and diameter are two variables that correlate each other through relationships that can be formulated through mathematic functions. To determine the best adjusting function between total height and diameter taken at 1.30 m above ground, 185 individuals of Black Mesquite from a native forest at the INTA Experimental Station in La Maria, Santiago del Estero, Argentina were measured along the period 1995-1996. Twelve lineal, non lineal and intrinsically lineal models were tested using the minimum squares method. The objective of this paper was to find the function that best estimate Black Mesquite total height in terms of its diameter in a given area of Santiago del Estero, Argentina. That introduced by Petterson proved to be the best.
