Avoiding edge effects in agroforestry experiments; the use of neighbour-balanced designs and guard areas

  title={Avoiding edge effects in agroforestry experiments; the use of neighbour-balanced designs and guard areas},
  author={Steve Langton},
  journal={Agroforestry Systems},
A number of different types of edge effects on experimental plots are defined, and it is shown that they are frequently important in agroforestry experiments. Methods of eliminating edge effects, either at the design or the analysis stage, are described. Computer simulations, based on uniformity data, are used to investigate the efficacy of neighbour-balanced designs, with and without neighbour terms, for reducing the problem of neighbour effects between different treatments. It is concluded… CONTINUE READING
