Impact of soils and cropping systems on mineral composition of dry cacao beans
In view of its high economic value, cacao (Theobroma cacao L.) scientists are seeking technological innovations that increases production and improve quality of cacao beans. The objective of this study was to characterize the mineral (N, K, P, Ca, Mg, Si, Fe, Mn, Zn, Cu, Cd, Ba) composition of cacao...

Sumario: | In view of its high economic value, cacao (Theobroma cacao L.) scientists are seeking technological innovations that increases production and improve quality of cacao beans. The objective of this study was to characterize the mineral (N, K, P, Ca, Mg, Si, Fe, Mn, Zn, Cu, Cd, Ba) composition of cacao beans of clone PH-16 grown in different soil types (Argisols, Cambisols and Latosols) and cropping systems (Cacao Cabruca, Cacao x Erythrina and Cacao x Rubber). With the exception of nitrogen, K was the mineral element most accumulated by cacao beans of PH-16 clone. Potassium, Ca, P and Mg mineral content of dry cacao beans were positively correlated with each other and showed similarity in clusters of average contents in relationship to the different cropping sites. Silicon content in cacao beans is proportionately close to the content of macronutrients. Variations in the content of Mn, Fe, Zn, Cu, Cd and Ba in cacao beans were related to the cropping sites because these mineral elements did not show any significant correlations with each other. Barium contents observed in this study correspond to levels of other micronutrients. In four sites, Cd content was higher than the limit set by the European Union. |
