CRD, or Completely Randomized Design, is a fundamental experimental approach where treatments are randomly allocated to experimental units, ensuring an equal chance for each unit to receive any treatment. However, CRD is best suited for situations where the experimental material is uniform or homogeneous. Due to the typically significant variation among experimental plots in field settings, CRD isn't the preferred choice for such experiments. Conversely, in laboratory and greenhouse settings, where experimental conditions can be tightly controlled, achieving homogeneity in experimental materials is more feasible. Therefore, CRD finds its greatest utility in these controlled environments.
