Interaction effects terms are indicated by a connecting colon. Degrees of freedom (d.f.) and denominator d.f. (d.d.f.) are given for each term along with F-statistics and P-value.

The whole plot Tank error term was negative, exceeded the residual variance, and was omitted as this made the model nonestimable. Note that in the same model whole plot treatment terms were nonsignificant and therefore also omitted.
