SUMMARY

A series of balanced bipartite row-column designs (BBPRC- designs) in to sets of treatments with v1 = 4t+3 (test treatments) v2 = 2t+2 (Control treatments) with varying replication has been obtained by supplementing a set of v2 = 2t+2 treatments in blank positions of non orthogonal RC design of Agrawal (1966). Such designs find applications in agricultural and industrial experimentation where the investigator wishes to provide unequal replications to two set of treatments or wishes to estimate the two sets with different precaution and at the same time wants to estimate heterogeneity due to two sources. The variances for different types of comparison has also been worked out.

Key Words: BBPRC design. General efficiency balanced designs, non-orthogonal row-column designs.
