The model terms were added sequentially. The columns show the degrees of freedom corresponding to the additional model term, the resulting change in deviance, and the p value when likelihood-ratio chi-squared tests are used to test for significance. Sets 0 and B were grown in one year at one location. Set A was grown in two years at one location
* Applies only to set A. ** Numbers on the left show degrees of freedom in sets 0 and B, while numbers in brackets show degrees of freedom in set A
