The estimation of the growth and the yield of timber forest species is a decisive activity in the sustainable planning and projection of the forest harvest. The purpose of the present study was to adjust four regression models to estimate the diameter, basimetric area, height and volume growth of Pinus leiophylla, Pinus lumholtzii and Pinus strobiformis in Guadalupe y Calvo, Chihuahua, Mexico. Through selective sampling, 26 Pinus lumholtzii trees, 26 P. strobiformis trees, and 30 P. leiophylla trees were collected in order to generate 219, 249 and 385 profiles, respectively, of each of these species. The adjusted models utilized were those of Chapman-Richards, Schumacher, Hossfeld I and Weibull. The criteria for selecting the best-adjusted models were the coefficient of determination, the root mean square error, the significance of the estimated parameters, and the growth tendency curves. All the models were well adjusted; however, when the growth and yield projection curves were considered, the models that best represented the biological growth trend of the tree species were those of Chapman-Richards, Hossfeld I and Schumacher. Considering the age of maximum growth and the rotation age, the studied species exhibit a low growth.
