Relative Efficiency of Latin Square Design with <I>Eucalyptus</I> in Shiwalik Hills

Abstract

The efficiency of various Latin Square Designs (LSD) relative to the Complete Randomised Designs (CRD) and Randomised Complete Block Design (RCBD) for various sizes and shapes of plots with height and diameter at breast height (D.B.H.) of Eucalyptus in Shiwalik hills were worked out. The relative efficiency (percentage) of 3 × 3, 4 × 4,5 × 5 and 6 × 6 LSD for different plot sizes and shapes compared with CRD and RCBD when rows are treated as blocks (ignoring columns) and when columns are treated as blocks (ignoring rows) have been computed. The number of units required in CRD and RCBD taking rows as blocks or columns as blocks for obtaining the relative efficiency equivalent to that of3 × 3 to 6 × 6 LSD were also evaluated and it was found that LSD was more efficient than CRD and RCBD for experimentation with Eucalyptus trees height and D.B.H. in Shiwalik hills.
