Abstract :In West Africa, little attention has been given to the rapid propagation of sweet potato with much dependence on the use of tuber part as seed. This study thus investigated the propagation and establishment of a different number of nodal segments of sweet potato vines in soil and soilless system under the influence of Arbuscular Mycorrhizal Fungi insert ignore into journalissuearticles values(AMF);. Cut vines insert ignore into journalissuearticles values(double and single nodal explants); from growing sweet potato plants were planted in the following substrates; Topsoil, Cocopeat, and Cocopeat + 5 g AMF insert ignore into journalissuearticles values(4 kg each fertigated with 250 g poultry manure);. The experiment was conducted twice insert ignore into journalissuearticles values(March to July and August to December 2021);. The experiment was a 2 insert ignore into journalissuearticles values(nodal explants); x 3 insert ignore into journalissuearticles values(substrates); x 2 insert ignore into journalissuearticles values(periods); factorial arranged in a completely randomized design with three replicates. The agronomic and yield parameters were collected and analysed using Analysis of Variance insert ignore into journalissuearticles values(ANOVA);, and means were separated using Duncan Multiple Range Test insert ignore into journalissuearticles values(DMRT); at 5% level of significance. At 4 Weeks after Planting insert ignore into journalissuearticles values(WAP);, the number of new leaves produced by the nodal explants was insignificant. At 8 WAP, the number of nodes produced differed significantly among substrates and ranged from 17.67±0.42 insert ignore into journalissuearticles values(cocopeat); to 20.17±0.42 insert ignore into journalissuearticles values(cocopeat+5g AMF);. Number of tubers produced differed significantly between planting periods and ranged from 3.28±0.41 insert ignore into journalissuearticles values(March to July); to 5.06±0.41 insert ignore into journalissuearticles values(August to December);. For efficient vine rooting, planting of single node vines of sweetpotato in cocopeat substrate fertigated with poultry manure and AMF between the August to December period of the year is thus recommended.
