ABSTRACT
In agricultural experiments in which a number of independent variables or factors often have an impact on one another, it is not appropriate to use single-factor experiments (discussed in the previous chapter.) This chapter deals with the experimental designs that permit the experimenter to study a number of independent variables within the same experiment. Such experiments that consist of two or more combinations of different factors are referred to as factorial experiments. Another way of looking at factorial experiments is that they are ones in which all, or nearly all, factor combinations are of interest to the researcher.
