The aim of this study is to compare the efficiency of split plot design relative to completely randomized design, randomized complete block design and Latin square design using their error variances. The data collected on the soil variability and methods of soil preparation were analysed using SPSS software. The results from the analyses showed that split plot design was more efficient than completely randomized design, randomized completely block design and Latin square design for split-plot comparison and less efficient than completely randomized design and randomized completely block design but more efficient than Latin square design for whole-plot comparison. It was therefore concluded that for maximum leave area of African yam bean, the experiment should be performed using split-plot design instead of completely randomized design, randomized completely block design or Latin square design by assigning the levels of poultry manure to the split-plot and the levels of phosphorus application to the whole-plot.
