§    ABSTRACT: Condition under which the statistical methods for inference about the parameters of a linear regression model can be used as approximations of the Mitscherlich’s second law are indicated. These conditions are set up by observation, mainly of the position of the parameter estimates in respect to the surface of the sum of square. For this purpose, the Mitscherlich’s Second Law is adjusted to tem data group of sugarcane maturation, expressed in pol per cent of cane.

§    KEYWORDS: Non-linear regression; parameter estimation; surface of sum of squares; Mitscherlich’s Second Law.
