Abstract:
SUMMARYIn Côte d'Ivoire, the world's largest cocoa producer, cacao (Theobroma cacaoL.) is usually grown from seed. The genetics consist of a mix of amelonado, trinitario and selected hybrids. This mix of varieties generates high phenotypic variabilities, including variability in tree productivity, within cacao populations in both smallholder and industrial plantations. Tree-to-tree variability in yield has been reported in cacao breeding trials under different environmental conditions. However, it has never been considered a limiting factor for agronomical performance of seedling-based cacao p

L'auteur propose une interprétation de l'économie de plantation ivoirienne depuis sa phase minière ou pionnière jusqu'à sa phase de raréfaction des facteurs de production : terre, foret, travail. Le problème de la reproduction ou de la disparition de l'économie de plantation est pose. L'économie de plantation ivoirienne s'est construite sur la rencontre de la terre et du travail, entre ceux qui détenaient initialement la terre, principalement les "autochtones" et ceux qui contrôlaient le travail, principalement les "allogènes". De cette rencontre, le capital est absent. Il y a bien un paradoxe

This chapter examines the agricultural strategies used in Amazonian cacao and sugar plantations. Cacao is a tree native to the region whose fruit was exported since the colonial period. Producers relied on the river tides for soil fertilization and combined its cultivation with the exploitation of wild groves. Sugar producers adopted a similar approach, using tidal energy as a natural fertilizer and as a source of energy to propel their mills. Amazonia was able to successfully develop a slave economy that produced tropical crops for markets overseas. It also discusses the impact of Cabanagem o
