Abstract

In large field experiments, the precision of randomized complete block (RCB) design is reduced because of the heterogeneity in field condition. Alpha lattice design (ALD) provides better control on experimental variability among the experimental units under field conditions. Each replication is divided into incomplete blocks and that blocks with in replication error will be eliminated from total error, so that the precision will be increased. The data from an experiment conducted in ALD with 22 entries, three replications and each replication divided in to two blocks was used for this study. The results indicated that RCBD should be replaced by alpha lattice when more than 10 treatments were compared.
