This study was conducted at the sawmill Inversiones R&D E.I.R.L., located in the department of Madre de Dios, in the province and district of Tahuamanu. The main objective of the research was to determine the sawmilling yield of the Apuleia leiocarpa species, considering the diameter classes, the quality of the logs adapted from INRENA-UNALM (2008) and the products obtained. A sample of 60 logs was taken, taking as a reference the INRENA-UNALM (2008) study which establishes a pre-sample to find the variability of the volume. Thirty-seven percent of the logs belonged to quality 2 and 63% to quality 3. Quality 1 was not found because all of the logs evaluated had some type of defect, especially in the shape of the log section. The log volume of quality 2 was 18,535 m3 representing 37% of the total volume and the log volume of quality 3 was 45,442 m3 representing 63% of the total volume. The total roundwood volume was 63,977 m3 and 21,343 m3 of sawn volume was obtained, giving an average total yield of 31%. Within the yield of the products, it was found that the yield of log volume to decking volume was 17%, identifying that 76% of the volume comes from quality 3 logs. The average yield of log volume to recovery volume was 14%, and 71% of the volume was found to come from quality 3 logs. The main log defects affecting yield were oval section, semi-sinuous and sinuous straightness, hollows, splits and cracks. Of these, hollow, splitting and rotting defects occurred mostly in larger diameter classes. The statistical analysis evaluated the equation models considering the categorical variables (log defects) and the predictor variables (diameter and length), finding that there were no notable statistical differences between the two models, opting for the predictor variable equation (diameter and length) because it was simple and practical. Afterwards, the yield tables for the volume of sawn timber and decking volume were prepared.
