In: Mansoura Unviersity Journal of Agricultural Sciences 2006.v.31(4)Summary: Soil variability affects experimental results and we can minimize this effect by choosing a proper design and the use of optimum number of plots, blocks, samples as well as their sizes. This study aimed to investigate effect of these Interrelationships on experimental and sampling errors, relative efficIency and coefficient of variation (C V) as measures of accuracy for randomized complete block design in sorghum experiments. Two uniformity trail were conducted at Shandweel Agricultural Research Station, Sohag Governorate during 2004 and 2005 seasons Dorado variety was used in both seasons. Total field area was 22875 m' (0.545 feddan ) for each trial that divided into 6 strips consisted of 120 ridges each considering ridge as the basic unit. Samples consisting of 5, 10, 15, 20, and 25 plants and data were assigned in randomized complete block design with different number of plots (k), blocks (b), sample (s) as well as their sizes in the two seasons
