Abstract

The work to investigate the effect of sett sizes on the field performance of white yam (Dioseorea rotundata) was done in Delta State Polytechnic Demonstration farm, Ozoro between March, 2016 and September 2016. Sett sizes classified into six groups/classes (2.0-5.0g), (5.01-10.0g), (10.01-20.0g), (2.01-30.0g), (30.1-40.0g) and (40.01-50.0g) were used in the experiment. The result indicates that no significant difference exist in average tuber size among three different classes: (2-5.0g), (5.01-10.0g) and (20.01-30.0g). thus it is recommended that sett class of 2.0-5.0grams should be used for multiply seed yam production technology under adequate cultural management.
