Item Cacao Yield in Different Planting Densities(2009) Carlos Alberto Spaggiari Souza; Luiz Antonio dos Santos Dias; Marco Antonio Galeas; Sabrina Sonegheti; Jeferson Oliveira; Jorge Luiz Andrade CostaThe effect of six planting densities on cacao yield of a commercial hybrid mixture as well as the interaction of planting densities with the years were investigated. Crop data collected over a 14-year period (1977-1990) showed that it was possible to optimise the regional cacao yields by implementing high planting densities (2500 and 1736 trees ha-1). This was however only true for the first half of the crop period. In the second half, low planting density (1059 trees ha-1) attained the best yields. This change in the ranking of planting densities over the years confirmed the presence of density-year interaction. Alternatives to achieve high productivity in high planting density systems were presented and discussedItem Favorability, distribution and prevalence of witches‘broom disease of cacao in the State of Espirito Santo, Brazil(2018) Sanlai Santos Lima; Carlos Alberto Spaggiari Souza; Nara Geórgia Ribeiro Braz Patrocínio; Rangeline Azevedo da Silva; Renato Souza Gonzaga dos Santos; Karina P.
