The influence of minisett size and time of planting on the yield of seed yam (Dioscorea rotundata) in Abuja, Nigeria

The data is from an investigation of the influence of planting different minisett sizes at different periods on yield. The trial was carried out on the experimental field at IITA Abuja Station (9.164694 N, 7.345136 E) during the cropping seasons of 2015 and 2016. It was laid out in a Randomized Complete Block Design (RCBD) with three replications with nine treatment combinations: 30 g minisetts planted early (Early); 30 g minisetts planted 21 days after the early planting (Mid); 30 g minisetts planted 21 days after the mid planting (Late). Similarly, 60 g and 90 g minisetts were planted early, mid and late, respectively. The D. rotundata landrace ‘Meccakusa’ was used.
