Abstract : Bananas and plantains are rhizomatous herbs whose terminal bud produces the inflorescence. Each plant produces successively a series of bunches, each from a lateral shoot. The sequence can be repeated for 1 to 50 generations or more (Turner, 1994). Banana cropping systems are based on the succession of these individual plant cycles (production of buds, selection of suckers, initiation of inflorescence, harvest) whose inter-plant synchronism determines field harvest dynamics (number of bunches harvested each week). As a result, harvest dynamics can be characterised by oscillations whose amplitude and frequency vary with time, climate, and practices. The management of these cycles and their prediction are key issues for a sustainable production. The understanding of the long term behaviour of this system and its simulation are necessary to adjust the management of the field to the farmer objectives (concentrate or spread harvest over the year) and conceive sustainable systems.
