Designs for one-sided neighbour effects

In agriculture and allied subjects, the treatment applied to one experimental plot may affect the response on neighbouring plots as well as response on the plot to which it is applied. The tall varieties may affect other crops grown on neighbouring plots by their shades. These effects are variously called neighbour effects or competition effects or interface effects. This paper is concerned with the study of one sided neighbour effect only. The merits and demerits of the designs are also discussed. Table and methods of applications for different designs are also presented
