Design of field experiments in the presence of interference between
treatments

R. A. Bailey

School of Mathematical Sciences, Queen Mary, University of London

In many types of field experiment it is likely that the treatment
applied to one plot will affect neighbouring plots as well as the plot
to which it is applied.  Such an effect is variously called a
neighbour effect, or interference between treatments, or competition
between treatments.   Where such effects exist, we need not only to
model them in the analysis but also to design the experiment with the
neighbour effects in mind.  This talk will give examples from various
different types of treatment, discuss   some of the issues, and give
some recommendations for design, some derived theoretically,
some more ad hoc.
