The objective of this paper is to show the results of the study on the non-linearity degreee of the Mitscherlich model. Some procedures are presented in a simple way in order to help researchers in their needs in adjusting and in evaluating nonlinear models with a high degree of reliability in their inferences. The Gauss-Newton method has been used in the estimation of parameters. Simulations, diagrams and tests have been used to evaluate the characteristics of the estimators. To achieve the proposed objectives, all needed computational procedures have been executed in the Computer Center of Londrina State University. The data, jrom Perre (1978), have been submitted to StatisticalAnalysis System (SAS).
