ABSTRACT Field experiment was conducted at the University of Ilorin sugar research field, southern guinea savannah zone during the 2010 cropping season. The study compared the rate of development of banana and plantain using propagated sword sucker of five replicate per treatment. The rate of development was measured as number of leaves per treatment, plant base circumference, length of the leaf and breadth of the leaf. There was a positive relationship between the two treatments but the development observed in banana was faster compared to plantain, whose development was gradual. There was significant difference among the two treatment from the second week of propagation to the twelfth week using plant circumference, leaf length, leaf breadth but the second week of propagation in leaf number is non significant.
