Augmented BIB Design-An Alternative Statistical Design in Germplasm Evaluation Trials

Randomized Block Design (RBD) is commonly employed to evaluate a set of germplasm accessions (test treatments) along with local checks. In such a trial, if the test treatments under evaluation are more in number and the availability of the seeds is limited, then an alternate experimental design has...
