(statistics)
An experimental design in which the various treatments are reproduced in each of the blocks and are randomly assigned to the units within the blocks, permitting unbiased estimates of error to be made.

in which q[alpha](i;GLE) is the critical value of the Tukey test at the [alpha] level of error probability ([alpha] = 0.05 in this study), i is the number of treatments, GLE is the number of degrees of freedom for error, i.e., i (r-1) for a completely randomized design and (i-1)(r-1) for a randomized blocks design, QME is the squared mean of the error, r is the number of replications and m is the experiment mean.
Greenhouse pot experiment included 40 tomato accessions grown under optimal irrigation and drought (volumetric soil water content 35.0% and 20.9%), designed in complete randomized blocks. Observations were made at the intensive vegetative growth phase.
For each character evaluated were simulated experimental designs for the designs completely randomized (DCR), in randomized blocks (DRB) and Latin square (DLS), for the scenarios formed by combinations of I treatments (I = 3, 4, ..., 30), r replications (r = 2, 3, ..., 10) end d differences between treatment mean being detected as significant at the 5% probability, express in percent of overall mean of the blank test (d = 5, 10, 15 e 20%).
In this stage, the participants completed 96 trials, consisting of four randomized blocks of 24 randomized trials each.
