The implementation of agroforestry systems in the Amazon can be an alternative to traditional land use and occupation models, as they are based on crops that favor nutrient cycling, based on the association of aerial and underground extracts between forest and agricultural species. Thus, the objective was to evaluate soil chemical conditions under...

The objective of this study was to investigate the behavior of physical attributes and soil carbon stocks in multi-stratified agro forestry system (AFS) compared to different types of land use, including cocoa plantation in agroecological management (CAC), pasture (PAS) and native forest (FLN). The treatments were installed at CEPLAC experimental s...

The minimum harvest period for evaluating cacao cultivars was investigated. 'Maranhão', 'Pará', 'Parazinho' (non-improved local cultivars) and ehte open-pollinated 'ICS 1' and the commercial hybrid mixture (improved cultivars) were evaluated in a 5 x 5 Latin square design containing 196-plant plots, during 10 years (1984-1993). The number of health...

Investigou-se o período mínimo de colheitas sucessivas necessário para avaliação do desempenho de cultivares de cacau. Os cultivares locais não-melhorados 'Maranhão', 'Pará' e 'Parazinho', juntamente com os cultivares melhorados 'ICS 1' polinização livre e híbrido comercial, foram avaliados em quadrado latino 5 x 5 com parcelas de 196 plantas, dura...

Cocoa cultivar performance temporal stability is an important factor for planters. This article proposes an evaluation of yields over ten years, based on a trial of a mixture of recommended hybrids, and one introduced and three local cultivars. Their respective performances and temporal stability were studied depending on various yield components....

UENF). 28013-602, Campos dos Goytacazes, Rio de Janeiro, Brasil. tonygama@uenf.br. RESUMO O estado de Rondônia possui uma agricultura migratória que promove o surgimento de extensas áreas em processo de degradação ambiental.
