RCB REPEATED IN TIME
Field marks: Multiple measurements of the
same experimental subjects are made in time.
Treatments are assigned at random within blocks of adjacent subjects, each treatment once per block.
The number of blocks is the number of replications.

RCB REPEATED AT MORE THAN ONE LOCATIONField marks: Blocks are laid out at more than one location.
Treatments are assigned at random to those blocks as below.
Treatments are assigned at random within blocks of adjacent subjects, each treatment once per block.
The number of blocks is the number of replications.
Any treatment can be adjacent to any other treatment, but not to the same treatment within the block.
