The relative efficiency of split-plot design (SPD) to randomized complete block design (RCBD) was computed using their error variance, sensitivity analysis and design planning. The result of this work showed that conducting an experiment using split-plot (SPD) without replication is more efficient to randomized complete block design (RCBD) based on comparison of their error variances, sensitivity analysis and design planning consideration.

Keywords: Split-plot Design, Randomized Complete Block Design, Error variance, Sensitivity Analysis and Design planning.
