Comparative Efficiency of Randomized Complete Block Design Vs. Latin Square Design in Wheat Yield Trial

Abstract

The use of proper design in agricultural experimentation is very important for getting precise results. The comparative study of two major designs i.e. Randomized Complete Block Design (R.C.B.D) and Latin Square Design (L.S.D) was conducted through field experiment. The experiment was carried out with wheat variety Pirsabak-2004 during 2013/14 at Agricultural Research Institute Tarnab, Peshawar, Pakistan. The area allocated for RCB design was 0.247 hectare and area for LS design was allocated to be 0.08 hectare. The accuracy of crop designs was examined by judging the degree of variances in error of both designs and by comparing the efficiency of the experiments including the effect of degree of freedom. The relative efficiencies of RCBD and LSD were calculated to be 1.002 and 0.60 respectively. Therefore, based on the present findings it can be concluded that RCB design is appropriate for the experimental designing relative to LS design.
