Conteúdo: | The spatial and sequential arrangement of crop plant populations in cropping systems, as a means of increasing food production in the tropics, has been given considerable attention by many investigators. When more than one species of crop plant populations are planted within sufficient spatial proximity to result in interspecific competition, the resulting polyculture cropping system has characteristic properties which can be identified and considered in the design of other polyculture cropping systems. A polyculture cropping system was designed by considering general characteristics of biomass compartmentalization during natural succession. The succession polyculture cropping system was evaluated in experiments at Turrialba, Costa Rica. The experiments were designed to allow an investigation of the characteristic properties of polyculture cropping systems by computer simulation. Beans (Phaseolus vulgaris L.), corn (Zea mays L.), and manioc (Manihot esculenta Crantz) were planted separately in three monoculture cropping systems, and together in three polyculture croppins systems. The polyculture cropping systems consisted of a succession polyculture in which beans, corn, and manioc were all planted at the same time and harvested after 9, 18, and 36 weeks respectively, a reverse polyculture in which manioc was planted alone and then interplanted with corn after 18 weeks and beans after 27 weeks, and all crops harvested after 36 weeks, and an intesive polyculture in which four bean crops, two corn crops, and one...
