Abstract
In this article, nested partially balanced treatment incomplete block (NPBTIB) designs are introduced for making test treatments-control treatment comparisons. Several methods of constructing such designs are presented. These methods of constructions utilize group divisible treatment (GDTD) designs, nested balanced incomplete block (NBIB) designs, and nested partially balanced incomplete block (NPBIB) designs. A catalogue of efficient NPBTIB designs with 2-associate classes for the number of treatments replications of test treatments and replications of control treatment is also included.
