Balanced Incomplete Block Design; Treatment contrast; Confounding; Factorial experiments.Abstract
This article focus on concept of constant block-sum designs through confounded factorial. Confounded factorial designs are shown to provide a rich
class of constant block-sum designs. The approach given by Khattree (2022) provides a direct and straightforward proof of the necessary condition
for existence of constant block-sum designs. Based on this the method of construction of constant block-sum designs through confounded factorial
given by Gupta (2022) is also mentioned. Some designs given by Gupta (2022) are estimated at different values, along with that some more designs
based on various effects confounded in different replications are presented to show existence and non-existence of constant block-sum designs in
different replications.
