A least-squares method using Marquardt's algorithm is used to fit crop growth data to a non-linear growth model. This non-linear model is expressed as a differential equation which cannot be integrated analytically. For comparison purposes, two other non-linear models based on the logistic and Gompertz equation are fitted to the same data. © 1984.
