- Abstract
Prosopis alba is one of the most widely used native forest species for sawmilling in Argentina. The forestry development law N° 27.487/19 considers the plantation of this specie taking into account densities and suitable practices for quality wood achievement. Coupled with good management right selection of the origin of the genetic material is a strategy that contributes to obtain good yields. In order to evaluate the behavior of P. alba three provenances plants were established in Corrientes and Chaco to assess their performance in these environments. It was worked with seedlings compound by seeds from the provenance of Santiago, Chaco and North Salta. As established on field, net response rate and four dasometric variables (total height, diameter at neck height, standing tree volume and annual current increase) were evaluated. Effect of plants' geographical origin over survival was not detected. In consideration of dasometric studied parameters, North Salta provenance was higher than the ones from Chaco and Santiago. In Sáenz Peña (Chaco) for this provenance all the evaluated dasometric variables were statistically greater, whereas in Corrientes they only were the diameter at neck height and total height. It has been proved that North Salta provenance stands out as the one with the best behavior in both tested locations. Therefore, it is concluded that the geographic origin of P. alba germplasm influences its productive behavior.
