WebA CRD requires that each replicate of a treatment is randomly assigned to an experimental unit (a plot within the larger main field in this case), whereas a RCBD requires that treatments are randomized within each block individually. Multiple randomization events occur in an RCBD, but only one randomization occurs in a CRD. It is Web1. Factorial (no split), arranged as a CRD; 2. Split-plot, with main plots arranged as a CRD; and 3. Split-plot, with main plots arranged as an RCBD. 12. 3. 1. Factorial (no split), arranged as a CRD.
