To compute F, we need to calculate the variation among the means of the three groups compared to the variation within each group. This means that there are two sources of variation: one between groups (among the three fertilizers) and one within groups (within each fertilizer). Therefore, the degrees of freedom (df) in the numerator would be the number of groups minus one, which is 3-1=2. Therefore, the correct answer is C.
